We are Stellar
Where cutting-edge technology meets influencer marketing passion.
Welcome to Stellar Tech.
Founded by Cathy Pill and Sarah Levin Weinberg—two determined entrepreneurs committed to the Women In Tech movement—Stellar was born from a shared vision: to make influencer marketing more effective, transparent, and accessible to all.
With offices in Paris, Brussels, and Copenhagen, and a presence in over 35 countries, Stellar Tech has established itself as a leading European scale-up while staying true to its roots. We firmly believe that success in influencer marketing is built on three pillars: trust, authenticity, and innovation. That’s why we developed Stellar, a platform that combines the power of artificial intelligence with human expertise to help brands identify and collaborate with the most relevant content creators while promoting responsible and sustainable practices.
In 2024, Stellar Tech expanded its SaaS portfolio by acquiring the Creatorz marketplace, renowned in the Benelux region for effectively connecting brands and content creators. This acquisition strengthens our leadership position by offering increasingly comprehensive and market-adapted solutions.
In 2025, Stellar Tech has further extended its European leadership by acquiring IROIN®, the leading influencer marketing platform in Germany. This strategic acquisition strengthens our presence across the DACH region while combining IROIN®’s innovative regional expertise with our advanced AI capabilities. As part of this exciting new chapter, we welcome Mathis Betz (IROIN®’s CEO) as our Chief Commercial Officer and André Kilz (IROIN®’s CTO) as Chief Product Officer to our leadership team.
Our mission
At Stellar Tech, our mission is to democratize influencer marketing by making it more efficient and accessible for businesses of all sizes and levels of experience.
How? By developing smart, user-friendly technological solutions and educating our industry and clients through training sessions and regular publications on trends and best practices.
This allows our clients and partners to navigate the complex Creator Economy confidently, identify influencers who align with their values and goals, and precisely track their campaign performance.

#RESPONSIBILITY: Promoting ethical influencer marketing is a top priority for us. By collaborating with industry-leading organizations like ARPP and IMH and integrating key features into our platform, we actively contribute to the positive and responsible evolution of our industry.
