I'm Ghassen, founder of Collabios. Collabios is an influencer marketplace where brands find and book creators for collaborations. Brands are international, including the US, and the creators are European. Founded in 2025 by Lustrace Digital OÜ in Estonia, bootstrapped, and active across 30+ markets. Alongside the marketplace there are 16 free tools that need no signup, including Instagram and TikTok follower counters. Building it in public, and feedback from other makers is very welcome.
