About This Launch
Collabios is a marketplace where international brands book European content creators directly. It also offers free tools that need no signup, including rate and engagement-rate calculators, an invoice generator, and contract and ad-disclosure generators for creators and brands. Built in Estonia.
Why I Built This
Collabios was founded in 2025 in Estonia and is bootstrapped. The free tools work without an account, so creators and brands can use them before deciding whether to sign up.
