Every European influencer marketing tool reviewed
Tallinn, Estonia
Essentials USD 199 per month, Performance USD 499 per month, Enterprise from USD 14,700 a year
14-day free trial, no card; no permanent free tier
Best for: Small teams that want self-serve creator search with a real price
Modash is the tool most buyers meet first because the price and the product are both visible before any conversation.
Three tiers are published: Essentials at USD 199 a month for two team members, 300 opened profiles and 100 tracked creators, Performance at USD 499 with creator payments and affiliate links, and Enterprise from USD 14,700 a year. A 14-day trial needs no card. That combination of visible prices and a cancel-any-month stance is rare among platforms of this size, and it is the main reason small brands and freelance marketers start here rather than with a quote-only suite.
The company is Modash OU, registered in Tallinn, with an additional office in Toronto. Discovery covers a large creator index with audience demographics, a shared inbox for outreach, post and story tracking and a Shopify integration.
Payments and affiliate-link management carry a 0% platform fee up to USD 10,000 a year in volume on Performance. Enterprise raises the payment and affiliate fee-free thresholds to USD 100,000 a year and makes every limit customisable, so a programme that outgrows the second tier has a published next step rather than a blank quote.
What it does not do is run the whole campaign. Contracting, briefing templates and a full workflow live in a spreadsheet or another tool once a programme passes a handful of collaborations a quarter.
Plan limits are consumed by opened profiles and unlocked emails, so a team that browses without a shortlist burns a month quickly. No ISO 27001 or SOC 2 is stated on the vendor’s site. Even so, for a team that mainly needs to find creators, verify audiences and track what they post, the scope is deliberately narrow and the price reflects that focus rather than hiding it behind a demo.
What Modash does well
- Published, self-serve pricing from USD 199 a month with no sales call
- Estonian company registered in Tallinn, so EU jurisdiction
- 0% fee on creator payments and affiliate links up to USD 10,000 a year on Performance
- 14-day free trial with no credit card
- Shopify integration and shared outreach inbox
Where Modash falls short
- No contracting, briefing or full campaign workflow
- Plan limits are used up by opened profiles and unlocked emails
- No permanent free tier, and the trial caps at 20 profile views
- No named third-party security certification on the vendor’s site
Standout feature. Fee-free creator payments and affiliate tracking up to a real volume threshold, inside the same published-price plan as discovery.
Loiu, Biscay, Spain
Free plan; Starter USD 69 per month, Plus USD 149, Advanced USD 229, all billed annually
Permanent free plan with 500 monthly search results, no card
Best for: Brands testing influencer search before paying anything
Heepsy is the only tool in this list with a permanent free plan rather than a trial: 500 monthly search results, 10 advanced profiles a month and one project, with AI, lookalike and text search, more than 30 filters and a basic creator CRM, no card required.
It is operated by Gemssy Technologies S.L., registered in Loiu in Spain’s Basque Country. For a brand that has never run an influencer programme this removes the usual first obstacle, a sales call and an annual contract, and lets a marketer see real filters and real results before any budget is requested.
Paid tiers are published. Starter is USD 69 a month billed annually (USD 89 monthly) and adds 5,000 monthly results, 100 advanced profiles, 300 outreach emails and a marketplace listing. Plus at USD 149 adds AI-composed outreach, sequences, creator payments and project analytics.
Advanced at USD 229 raises every limit and adds creator detection and priority support. Custom plans exist for larger teams, and the paid tiers all sit well below the entry price of the agency-grade suites, so the step from free to paid stays small enough for a single marketer to approve alone.
The product is search-first, with strong filters on country, follower band, engagement rate and fake-follower signals. Campaign management, contracting and reporting are lighter than in the dedicated suites, which is the trade for a free entry point.
Its fake-follower and engagement scores are indicators, not audits, and no ISO or SOC certificate is stated by the vendor. A buyer who outgrows it will usually move to a suite with contracting and reporting, but many small teams never need to, and the free plan is a fair way to find out which camp you are in.
What Heepsy does well
- Permanent free plan with 500 monthly search results and no card
- Published pricing at every paid tier, from USD 69 a month
- Spanish S.L. registered in the Basque Country
- Fake-follower and engagement signals available even on the free plan
- Creator payments and sequences arrive at the USD 149 tier
Where Heepsy falls short
- Campaign management and reporting are lighter than in the suites
- Fake-follower scoring is an indicator rather than an audit
- Higher limits sit behind the USD 229 Advanced plan
- No named security certification stated by the vendor
Standout feature. A real free plan with 500 monthly search results, which no other European tool in this category offers.
Saint-Mande, Paris area, France
Core from USD 159 per month, Pro from USD 239 per month on annual billing; Enterprise custom
7-day free trial; no permanent free tier
Best for: Teams that care about authenticity scoring built into discovery
Favikon is a French creator intelligence platform operated by MOOJITO SAS from the Paris area.
It scores more than 10 million creators across nine social networks on authenticity, authority and audience quality, and runs free public leaderboards, Favikon Rankings, across more than 600 niches alongside the paid product. Search works by description prompt, by content or by lookalike. The leaderboards are open to anyone, which makes Favikon unusually easy to sanity-check: a marketer can look up a niche and see how the vendor ranks creators before deciding whether the paid product is worth testing.
Pricing is published. Core starts at USD 159 a month billed annually (EUR 179, or USD 199 monthly) for 500 credits, 3,000 contacts, one active campaign and 100 tracked creators.
Pro starts at USD 239 and adds a Radar module, sponsored-post filtering, job-title filters, DMs alongside email, GA4 and an MCP integration. Enterprise adds API access and SEPA or wire payment. Prices are shown in US dollars with a euro equivalent, which is a small point but a useful one for a European buyer, since most of the category quotes in dollars only and leaves currency conversion to the invoice.
Vetting sits inside discovery: bot, engagement-pod and audience-mismatch detection, plus demographics by age, gender, geography and language. The limit is the operational side. Payments and contracts are marked coming soon, so a programme that needs payouts handled in the platform still needs another tool.
There is a 7-day trial and no permanent free tier. For a team that wants vetting rather than workflow, that is a fair trade today, and the roadmap items are worth confirming at contract time instead of assuming they ship on the date implied.
What Favikon does well
- Authenticity, authority and audience scoring built into search
- Published pricing from USD 159 a month with a EUR price shown
- Free public Favikon Rankings for a quick check before buying
- French SAS, so EU jurisdiction
- Pro tier includes an MCP integration for AI assistants
Where Favikon falls short
- Creator payments and contracts are not shipped yet
- Only a 7-day trial, no permanent free plan
- Core plan caps at 500 credits and one active campaign
- No named third-party security certification
Standout feature. Bot, engagement-pod and audience-mismatch detection is part of the same search instead of a separate audit product.
Madrid, Spain
Tiered, pay for what you need; exact tier figures are not published in a static table
7-day free trial on all plans
Best for: Agencies that need a persistent creator CRM and client reports
Influencity is a Madrid influencer marketing platform covering discovery, a built-in creator CRM, campaign tracking and reporting designed to be shown to a brand client.
The vendor sells on a pay-for-what-you-need model rather than one flat tier, with a 7-day free trial on every plan so a team can test discovery volume and reporting. For agencies that report to several brand clients the shared creator database is the part worth testing, because it changes the economics of every pitch after the first one a team has built a shortlist for.
Discovery covers audience-demographic filters and estimated engagement across the main platforms, and results feed a shared database a team builds over time, so nothing found in one search is lost for the next brief.
That persistence is the point: an agency’s shortlist and relationship history compound across briefs rather than restarting with each search. Reports are formatted to be forwarded to the brand client rather than only read internally, which is a practical difference from tools that export raw tables and leave the agency to build the slide deck.
The costs are specific. No simple price table is published, so a buyer has to configure a plan to see a number. Limits are consumed by profiles analysed rather than by campaigns, so undisciplined browsing exhausts an allowance.
Demographics are modelled estimates, not audited figures, and creator payments happen outside the platform in a separate finance process. No third-party certification is stated. None of that makes it a poor choice, but it does mean the buyer should ask for a configured quote early, run the trial with a real shortlist and agree in writing how analysed-profile limits are counted.
What Influencity does well
- Creator CRM that persists across campaigns
- Client-presentable reporting built for agencies
- 7-day free trial on every plan
- Spanish company in Madrid, so EU jurisdiction
- Modular pay-for-what-you-need pricing
Where Influencity falls short
- Current tier figures are not published in a plain table
- Allowance is consumed by analysed profiles
- Audience demographics are modelled estimates
- Creator payments are not handled in the platform
Standout feature. A creator CRM that compounds across campaigns, so an agency’s shortlist is an asset rather than a per-brief search.
Paris, France
Founded 2018
Annual licence quoted per organisation; no published self-serve pricing
No free tier; demo on request
Best for: European brands whose legal team wants disclosure rules built in
Kolsquare is a Paris platform registered as Kolsquare SAS at 124 rue Reaumur, founded in 2018 by its own account and a registered benefit corporation, a societe a mission, since 2020.
It builds around European regulation: GDPR-aligned creator data handling, contract templates and disclosure requirements that track the French influencer law on retouched images and permitted product sectors. That legal posture is the product’s clearest difference from search-first tools, and the reason a brand with in-house counsel or a compliance review should put it on a shortlist before comparing prices.
The product covers discovery and vetting, campaign and contract management, and reporting formats for agencies presenting to brands. Coverage is strongest in France, Spain and Italy; a buyer whose creators sit in the Nordics or Central Europe should test the index depth in a trial.
Kolsquare also took over the Italian platform Inflead, which now serves from the Kolsquare site. For Italian buyers the Inflead change is worth a question during procurement: which datasets, contracts and support arrangements now sit under the Kolsquare entity, and which are still handled by the former team.
There is no published price. Every deal is an annual licence quoted per organisation, so a small team cannot compare a number without a sales call.
For a company whose legal department wants disclosure and data handling inside the tool, that conversation is the cost of fit. No third-party security certificate is stated, and there is no free tier. A trial is possible through a demo, and a buyer should bring a real list of creators from their own markets to see how deep the coverage actually is before committing to a year.
What Kolsquare does well
- Disclosure tooling built for French influencer law and GDPR
- Registered benefit corporation since 2020, per the vendor
- Strong index depth in France, Spain and Italy
- Contract management and agency-style reporting
- French SAS with a named Paris address
Where Kolsquare falls short
- No published pricing, every deal needs a sales call
- Thinner creator coverage in the Nordics and Central Europe
- No free tier, demo only
- No named third-party security certification
Standout feature. Disclosure and data-handling features built specifically for French and EU influencer rules, which most competitors leave to the buyer.
Linz, Austria
Annual licence quoted per organisation; no published self-serve pricing
No free tier; demo on request
Best for: Established DACH brands that want creators who already mention them
Storyclash is an Austrian platform operated by Storyclash GmbH at Energiestrasse 1 in Linz.
Its starting point differs from most of the category: instead of a static profile database it monitors content to surface creators already posting about a brand, a competitor or a category, so the shortlist is people who have shown interest rather than a demographic filter match. Brands that already have a visible community, a product people photograph or a retail footprint tend to see the most value, since the platform has a lot of organic material to surface and rank.
For an established brand that is a warmer start than cold discovery, and coverage of Germany, Austria and Switzerland is a particular strength given the Austrian base. The product covers monitoring, discovery from organic mentions and campaign tracking.
It does not extend into contracting or creator payments, which happen elsewhere. It works best as the front end of a programme, finding the creators worth approaching, with the contract, briefing and payment steps handled by an agency, a spreadsheet or a separate finance process.
Pricing is not published: every deal is an annual licence quoted per organisation, normally a year’s commitment before a number appears. The approach also has a built-in limit.
A brand entering a category where nobody yet mentions it gives the platform nothing organic to find, so it is weak at the very start of a market launch. No free tier or certification is stated. A buyer comparing it with search-first tools should treat the licence as a monitoring subscription first and a discovery database second, and should ask what historical data comes with it on day one.
What Storyclash does well
- Surfaces creators already posting about your brand or rivals
- Strong coverage of the DACH region
- Brand monitoring, discovery and tracking in one product
- Austrian GmbH with a named Linz address
- Warm shortlist rather than demographic guesswork
Where Storyclash falls short
- No published pricing, annual licence by quote
- No contracting or creator payments
- Weak when nobody yet mentions the brand
- No free tier or stated security certification
Standout feature. Organic-mention monitoring is the discovery mechanism, so creators are found because they already talk about you.
Paris, France
Annual licence quoted per organisation; no published self-serve pricing
No free tier; demo on request
Best for: Fashion, beauty and lifestyle houses running gifting and events
Lefty is a Paris-headquartered platform with additional offices in New York and Shanghai, built for the rhythm of fashion, beauty and lifestyle: send product, host an event, see who posted and report the result per market and per house.
Gifting workflows and event-coverage attribution are handled more fully here than in most general-purpose platforms, which is why luxury groups choose it. The workflow follows the send, host and report sequence of fashion and beauty marketing, with product shipments and event coverage as first-class objects, rather than the performance-marketing logic of most platforms.
The headline reporting metric is earned media value, which converts impressions and engagement into a currency figure with a multiplier the vendor sets.
That number is not audited and is not comparable between platforms, so it belongs next to reach, engagement and traffic, not alone in a finance report. Brands that want to compare agencies or markets on a single number tend to find the metric useful internally and harder to defend externally, which is why it is best read as one line among several.
There is no published pricing; every deal is a quoted annual licence, a fit for agencies and houses running continuous programmes and a barrier for smaller teams.
Outside fashion, beauty and lifestyle the feature set, built around gifting and events, is narrower than a general-purpose campaign platform. No free tier or third-party certification is stated by the vendor. Smaller teams in other sectors will usually find a general-purpose suite or a search-first tool a better fit, and a trial should test the gifting module against a real seasonal campaign.
What Lefty does well
- Gifting and event-coverage tracking built for fashion and beauty
- Reporting per market and per house for multi-brand groups
- Established in the luxury and beauty influencer space
- French company headquartered in Paris
- Workflow matches how product seeding actually runs
Where Lefty falls short
- Earned media value is vendor-defined and not comparable
- No published pricing, annual licence by quote
- Narrow fit outside fashion, beauty and lifestyle
- No free tier or stated security certification
Standout feature. Gifting and event-coverage tracking designed around fashion and beauty campaigns, a workflow general platforms handle thinly.
Marseille, France
Annual subscription plus campaign packages, quoted per organisation
No free tier; demo on request
Best for: Consumer brands buying volume product-seeding content
Skeepers is a French platform headquartered in Marseille, with offices across Europe and the Americas, and it runs product-seeding campaigns at volume through a pool of small and micro-influencers.
The output is best read as content supply rather than reach: many creators receive product in exchange for content, and the cost per asset is low. For a consumer brand that wants many pieces of content rather than a few large placements, a large pool of small creators is the logic of the product, and the cost per asset is the number to compare.
The product covers campaign setup, product-gifting logistics, content collection and usage-rights management across a large pool, positioned for consumer brands that want a high volume of authentic content rather than a few high-reach placements.
Reporting focuses on content volume and usage-rights coverage more than on the reach of any single creator. Because usage-rights management is part of the offer, the platform fits brands that want assets for product pages and paid social as much as they want reach, and the usage terms deserve a close read.
A compliance point is specific to this model: a free product counts as payment under most disclosure rules, so every gifted post needs proper disclosure, and enforcing that across hundreds of micro-creators is a task the buyer carries, not the platform.
Quality is uneven across a pool that size. Pricing is an annual subscription plus campaign packages, quoted per organisation. Teams that want a small number of high-impact placements with named creators and negotiated deliverables will usually be better served by a search-first or suite product than by volume seeding.
What Skeepers does well
- Runs product-seeding campaigns at volume
- Usage-rights management built for gifted content
- Low cost per content asset compared with paid reach
- French company headquartered in Marseille
- Logistics for gifting handled in the platform
Where Skeepers falls short
- Content quality varies across a large micro-creator pool
- Disclosure compliance across gifted posts is the buyer’s risk
- No published pricing, subscription plus packages by quote
- No free tier or stated security certification
Standout feature. Volume seeding and usage-rights management across a large micro-influencer pool, built for content supply rather than reach.
Paris, France
Discovery EUR 540 per month, Project.AI EUR 1,080 plus EUR 490 onboarding, Marketplace EUR 1,350 plus EUR 490 onboarding, Pack Full Influence EUR 1,790 plus EUR 490 onboarding; local influence offer EUR 199 per month; UGC video ads from EUR 190 per video; all excluding VAT on a 12-month term
5-day free trial on Discovery; 30-day cancellation window on the larger packs
Best for: Brands that want search, marketplace and payouts at published prices
Influence4You is a Paris platform operated by Influence4You SAS at 229 rue Saint Honore, registered in the French company register since 2005, and it publishes module prices rather than hiding them.
Discovery is EUR 540 a month, Project.AI EUR 1,080, Marketplace EUR 1,350 and the full pack EUR 1,790, each excluding VAT on a 12-month term, with a EUR 490 onboarding fee on the larger packs. The company has been trading since 2005 according to the French register, which makes it one of the older European platforms in this list, though the vendor’s own pages describe eleven years of influencer-marketing experience.
The product spans a profile index the vendor puts at 275 million profiles in 160 countries, a marketplace where creators apply to campaigns, and campaign management with contracts, product shipments, budget tracking and payments.
Reporting covers views, earned media value, engagement and Shopify sales. AI features are described as powered by Mistral AI, a French provider. A competitive-monitoring module shows what brands in a sector are doing, and separate offers cover agencies managing several clients and UGC video ads priced per video from EUR 190.
Entry cost is the limit. At EUR 540 a month for discovery alone it is priced above the self-serve search tools, and the commitment is a year, with a five-day trial on Discovery and a 30-day cancellation window on the larger packs.
A local influence offer at EUR 199 a month targets shops and restaurants. No security certification is stated on the pages checked. Freelancers, start-ups, associations and NGOs can ask for a 50% reduction on the standard price, and longer commitments of 6, 12 and 24 months carry discounts, which softens the entry cost for smaller buyers.
What Influence4You does well
- Module prices published in euros, with a clear 12-month term
- Marketplace, contracts, shipments and payments in one product
- Shopify sales reporting alongside EMV and engagement
- French SAS registered in Paris
- EUR 199 local offer for small businesses
Where Influence4You falls short
- EUR 540 a month for discovery alone, above self-serve rivals
- Twelve-month commitment on standard terms
- EUR 490 onboarding on larger packs
- No third-party security certification stated
Standout feature. It is the only platform here that publishes full module prices in euros and bundles marketplace, contracts and payouts under them.
Brussels, Belgium
Founded 2018
Discovery Radar from EUR 299 per month, Campaign Manager from EUR 899 per month, Enterprise+ on request; every plan includes 3 users, billed annually by default with monthly available
Demo on request; no free tier stated
Best for: Agencies and in-house teams that need a CRM and reporting suite
Stellar is the Brussels platform of HeavenTech SA, a Belgian public limited company at Louizalaan 54, founded in 2018 by Cathy Pill and Sarah Levin Weinberg.
The same group, Stellar Tech, acquired the Benelux marketplace Creatorz in 2024 and the German IROIN platform in 2025, so one price list now covers three brands. IROIN is still sold under its own name by CrowdArchitects GmbH in Erfurt. In practice that means one European group now sells three brands in Belgium, the Netherlands and Germany, and a buyer should ask which entity signs the contract and which brand’s support team answers.
Prices are published from EUR 299 a month for Discovery Radar, which covers a 440 million creator index, AI search by image or content, audience authenticity, lookalikes, brand safety and competitor benchmarking.
Campaign Manager starts at EUR 899 and adds campaign automation, a customisable creator CRM, ROI and sentiment analysis and automated client reports. Every plan includes three users. The discovery tier also includes social listening and an MCP connection that lets an AI assistant query the creator data, which is a recent addition most competitors do not yet list on a pricing page.
Enterprise+ is quoted and adds API access, single sign-on and implementation support. Billing is annual by default with monthly available. The cost of the suite is in the step: EUR 299 buys search only, and the CRM and campaigns sit at three times that.
Payments are not listed among the features, and no ISO 27001 or SOC 2 is stated on the pricing page. Support is offered in four languages five days a week, and the group runs community events in Belgium, France, the Netherlands and Germany, which tells a buyer where the company’s own centre of gravity sits.
What Stellar does well
- Published entry prices of EUR 299 and EUR 899 a month
- Creator CRM, automation and client reports in the Campaign Manager tier
- Belgian SA verifiable in the Crossroads Bank for Enterprises
- Three users included on every plan
- MCP connection to ChatGPT, Claude and Gemini on the Discovery plan
Where Stellar falls short
- EUR 299 covers search only, campaigns start at EUR 899
- Payments are not listed as a feature
- Overlaps with IROIN and Creatorz, which are separate brands in the same group
- No third-party security certification stated
Standout feature. A published two-step price list for a 440 million creator index and a full CRM suite, from a company verifiable in the Belgian register.
Dublin, Ireland
Not published; quoted after a call for both the SaaS platform and the agency services
No free tier or trial stated; a call is the entry point
Best for: Teams that want a SaaS platform with an agency behind it
indaHash sells influencer marketing both as a SaaS platform and as agency services, and the contracting party in its Creator Discovery and Self-Serve terms is IDH MEDIA LTD, an Irish company at 22 Northumberland Road in Dublin, company number 563441.
The site claims more than 600 brands as clients and offers a regional selector that lists Poland and the United Kingdom among its options. The contracting entity named in its current terms is the Irish company, which is what governs a European buyer’s contract, whatever country the team behind the product works from.
The SaaS platform leads with AI: a campaign brief is turned into contextual creator search, with structured, AI-generated reasoning for each creator inside the workflow.
Campaign management covers briefing, a creator CRM, content approvals and moderation, with mass mailing, coupon integrations, payments and a Google Sheets API. Reporting includes one-click reports, real-time sales tracking and AI sentiment analysis. Self-serve and creator discovery have separate terms of service, and both name the same entity, which is a good sign for a buyer who wants to see exactly what governs the account.
What is missing is a price. Nothing is published, and the route in is a call, so a buyer cannot compare it with Modash or Stellar without engaging sales.
The hybrid with an agency can help a team without in-house capacity, and it can blur whether you are buying software or a managed service. No certification is stated on the pages checked. A buyer should ask early how fees are split between the platform and any managed services, what creator payments cost and which parts of a campaign remain with the agency team.
What indaHash does well
- AI search that starts from a campaign brief
- Creator CRM, approvals, payments and coupon tracking in one workflow
- Irish company with a named registered office and company number
- Agency services available alongside the software
- Google Sheets API for reporting
Where indaHash falls short
- No published prices or trial
- Hybrid of agency and software can blur what you are buying
- Service routes depend on the region you select
- No third-party security certification stated
Standout feature. It starts from the campaign brief rather than a filter set, and lets a team lean on an agency without leaving the platform.
Madrid, Spain
Founded 2018
No subscription tiers; each sponsored mention is priced per influencer account by an algorithm, and campaigns are paid in advance
Free registration; demo available
Best for: Brands that want to buy sponsored posts from a creator marketplace
SocialPubli is a Madrid marketplace run by SOCIALPUBLI S.L., incorporated before a Madrid notary on 25 September 2018 and registered in the Madrid company register.
Advertisers contract campaigns of sponsored mentions on Instagram, TikTok, YouTube, X, LinkedIn, Facebook, Twitch, WhatsApp and blogs, and influencers link their accounts to the platform directly or through an account manager. That makes it closer to an advertising exchange than to a CRM, and because the price per post is set by the platform rather than negotiated, procurement stays simple and the cost is known before a campaign starts.
The pricing model is different from the subscription tools. The platform generates a price for each sponsored mention for each influencer account through an algorithm that weighs followers, posting frequency and follower activity, and advertisers pay at the start of a campaign, before the mentions are made.
Influencers are paid after publication, as indicated on the platform. The terms also describe an arrangement where influencers can be represented by an account manager, which matters for creators who work through a talent agency and want the platform to deal with a single contact.
Around the marketplace there is a toolset: Discover for search, Analyzer for profile analysis, Brand Detector and a Boost and Advocacy offer.
There is no published plan table and no fee schedule on the pages checked, and the product is weaker for a named creator with a negotiated rate. No third-party security certification is stated. A buyer who needs contracts, usage rights or a CRM for repeat collaborations should treat it as a source of reach and test whether a separate suite is needed alongside it.
What SocialPubli does well
- Marketplace covering Instagram, TikTok, YouTube, LinkedIn and blogs
- No subscription, pay per campaign
- Discover, Analyzer and Brand Detector tools on the same account
- Spanish S.L. with a registered Madrid office
- Influencers are paid only after the mention is made, per its terms
Where SocialPubli falls short
- Prices are algorithmic per account, not a published table
- Weak for negotiating a specific creator’s rate
- No fee schedule on the pages checked
- No third-party security certification stated
Standout feature. A pay-per-campaign marketplace with algorithmic mention prices and payment collected before publication, with no subscription to maintain.
