Detailed Review

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.
