Best for: DTC brands where referral is the main loyalty lever
Mention Me is a London company that sells referral and word-of-mouth marketing only, with no points ladder or tiers. Its About page says it has delivered revenue for more than 500 brands since 2013, and it identifies customers likely to recommend a brand, runs the referral programme and reports what it earned. The pricing page asks for annual online revenue in bands from £0 to £7M up to £500M+ and then gives a custom quote.
The privacy policy names Mention Me Limited, registered in England and Wales under number 08382730, with its registered office at 20-22 Wenlock Road in London. Integrations on the About page include SAP, Emarsys and Trustpilot, and the home page describes a Meta advertising connection. No amounts or data location are published, so ask for both.

The terms of sale name AURA CORP., a simplified joint-stock company registered in Nantes under number 889 463 519 with capital of 18,000 euros, and the site lists offices in Paris and London.

Demo on request
Best for: Developer teams combining discounts and loyalty in one engine
Voucherify began as a coupon tool and now describes itself as an incentive optimisation engine, with referral campaigns defined as rules in the same engine as coupons, gift cards, loyalty and promotions. Because every incentive sits in one rule set, a referral reward is less likely to stack with a loyalty discount or a campaign code.
The privacy policy names Voucherify PSA, Porcelanowa 23, Katowice, as controller. The company says it serves more than 350 brands, is ISO 27001 certified and belongs to the MACH Alliance. Business costs €600 a month with 25,000 API calls and Organization €1200 with 50,000, and a 60-day trial is offered. The footer also shows a New York address, so confirm the contracting entity in the order form.
What Voucherify does well
- Coupons, loyalty and referrals in one engine
- Plan prices published in euros
- 60-day free trial
- ISO 27001 certified, per the vendor
- Polish company with a stated Katowice base
Where Voucherify falls short
- Starts at €600 a month
- Needs developer integration
- API call limits per plan
- Less suited to a simple points app
Standout feature. Voucherify manages referral rewards, coupons and loyalty in one rule engine and bills by API capacity in euros.
Amsterdam, Netherlands
Launch $89/month, Scale $179/month, Enterprise custom — published tiers, no override
Demo on request
Best for: Merchants running commission programmes who want flat, published monthly prices
Tapfiliate is an Amsterdam affiliate tracking platform whose referral module serves merchants that run their own programme. It does not supply publishers, so every affiliate is recruited by the brand, and it is sold as software rather than as a network.
Launch costs $89 a month for one programme, 50 affiliates and 5,000 clicks, and Scale costs $179 a month with no programme or affiliate cap and limits of 100,000 clicks and 10,000 conversions. Overage runs $1.50 per 1,000 extra clicks on Launch and $1.00 on Scale. Integrations number more than 30, including Shopify and Stripe, and every tier has a free trial of 7 to 30 days.
What Tapfiliate does well
- Published, predictable tiered pricing from $89/month with no percentage override on sales, unlike a network model
- No cap on programmes or affiliates from the Scale tier up ($179/month)
- 30+ integrations including Shopify and Stripe, plus server-side tracking and recurring-commission support
- Free trial on every tier, from 7 days on Launch up to 30 days on Enterprise
Where Tapfiliate falls short
- You recruit every affiliate yourself — Tapfiliate is software, not a publisher network like Awin or TradeTracker
- Overage fees apply once a tier's click allowance is exceeded ($1.00–$1.50 per extra 1,000 clicks)
- No third-party security certification (e.g. ISO 27001) stated on the vendor's public pages
Standout feature. Tapfiliate prices by clicks on flat monthly tiers, so a growing programme does not pay a share of each sale.

Best for: Brands running multi-channel loyalty programs
Antavo is a loyalty and membership platform that lists referrals as one feature next to tiers, rewards, challenges, clubs and a separate promotions and incentives module. A referral reward can therefore feed a points ladder or a time-limited challenge, at the price of more programme design before launch.
The privacy notice names Antavo Limited, registered in London under company number 08046168, and lists Antavo Kft. as an internal processor. It lists Google Cloud in the Netherlands and AWS storage in Ireland next to regions in Asia Pacific and North America. Pricing is quoted after a call.
What Antavo does well

- Separate promotions and incentives module
- Large listed partner network for integrations
- Quarterly product releases published by the vendor

Open Loyalty is an API-first loyalty engine from Wroclaw with multi-tier referral mechanics next to points, badges, coupons, leaderboards and games such as spin the wheel. A campaign builder and an admin interface sit on top, and the brand connects the engine to its own app or point of sale.
The privacy policy names Open Loyalty sp. z o.o. (KRS 0000929571), part of the OEX SA group, and the pricing page says it is not open source.

Demo on request
Best for: Merchants wanting detailed commission rules on published tiers
Post Affiliate Pro is affiliate software with a referral tracking edition, built by Quality Unit, s.r.o. in Bratislava since 2004. Its commission configuration includes multi-level commissions, multiple merchant accounts and Smartlinks on the top tier.
Starter costs $89 a month for 10,000 tracking requests, Pro $139 for 1 million with 220-plus integrations, Ultimate $269 for 6 million and Network $649 for 20 million. Overage is charged per 10,000 extra requests. The group also runs a Czech entity and a Delaware subsidiary, which matters for a buyer with a strict single-jurisdiction rule.
What Post Affiliate Pro does well
- Operating since 2004, one of the longer track records among the self-run software tools in this category
- Fully published pricing across four tiers ($89–$649/month), scaled by tracking-request volume
- Unusually deep commission configuration: multi-level/MLM-style commissions, multiple merchant accounts and Smartlinks on the top Network tier
- 220+ integrations from the Pro tier up, with full setup/integration assistance included
Where Post Affiliate Pro falls short
- Pricing scales by raw tracking-request volume, a less intuitive metric to estimate in advance than affiliate count or click volume
- Overage fees ($0.20–$5 per extra 10,000 tracking requests) apply once a tier's allowance is exceeded
- Primary legal entity is Slovak, but the group also runs a Delaware-registered US subsidiary (Quality Unit, LLC), worth noting for a buyer with a strict single-jurisdiction requirement
