European influencer marketing technology leader Stellar Tech has acquired Join, the Netherlands’ top creator platform, merging it with its existing marketplace, Creatorz, to create the Benelux’s most comprehensive hub connecting brands with content creators.

This marks Stellar Tech’s third strategic acquisition following Influo (July 2024) and IROIN® (March 2025), reflecting its ambition to consolidate Europe’s fragmented influencer market by combining local expertise with innovative technology.

Join’s AI-powered platform brings scale, technology, and a network of thousands of vetted creators and top brands in the Netherlands. When integrated with Creatorz, which dominates Belgium, the combined platform will connect tens of thousands of creators across the Benelux, giving brands access to a single, robust marketplace for flexible and premium collaborations.

Two Pillars, One Vision
Stellar Tech’s growth strategy is built on two pillars:

• Analytics: Stellar and IROIN® unify into a single analytics solution for creator discovery, management, and performance measurement.

• Marketplace: Creatorz, now strengthened by Join, enables instant collaborations across micro-influencers and UGC creators.

Cathy Pill, CEO & Co-founder of Stellar Tech, said: “The creator economy is evolving rapidly. With Join and Creatorz together, and Paolo and Edwin at the helm, we are creating the benchmark marketplace for micro and UGC creators in the Benelux. This move isn’t just about growth—it’s about shaping the future of influence, where collaborations are more diverse and accessible.”

Leadership and Vision
Join’s founders will take key roles within the merged platform:

• Paolo Martorino, former CEO of Join, becomes Creatorz Managing Director.

• Edwin Knip, former CTO of Join, becomes Tech & Product Lead.

Martorino added: “We founded Join to make collaborations between brands and creators simple and rewarding. By joining forces with Creatorz, we can expand this promise to a larger community, broadening the definition of the creator economy—from influencers to UGC specialists, from paid briefs to gifting—while giving brands a reliable partner for speed and authenticity.”

With this acquisition, Stellar Tech not only strengthens its market position in the Benelux but also signals its intent to be Europe’s leader in influencer analytics and marketplace platforms, combining advanced AI technology with deep local expertise.
