Honesty before signup
Who this is for, and who it isn't
Most cofounder relationships form through existing networks and in-person events. The directory exists for the founders that gap does not serve.
For you if
International founders in Finland without a built-in Finnish network.
Post-program founders still searching after Startup Express, Oyster, or Founders Corner.
Founders chasing a specific archetype their existing network can't supply.
Anyone testing collaboration before committing to cofounder framing.
Probably not for you if
Teams that already formed inside a class, cohort, or shared workplace. Proximity wins; no platform improves that.
Founders looking for a paid hire. This is a cofounder directory, not a job board.
Anyone expecting commercial outreach. There is none. The platform is hosting-cost-only.
From the Blog
Everything you need to know
We pull real signals from your LinkedIn, GitHub, startup website, and public work, then use AI to build a deep capability model. Instead of matching on keywords or self-reported skills, our engine scores complementarity: a business founder sees technical cofounders who fill their gaps, and a developer sees founders who need their engineering. We even surface gaps neither side has articulated.
Yes, completely free. Create a profile, browse potential cofounders, and start conversations at no cost. We are focused on helping you find the right cofounder for your startup.
LinkedIn is a generalist network where you post 'looking for cofounder' and hope someone sees it. Cofounder forums are self-reported profiles with no verification. TrustedCofounder pulls real work evidence, matches on complementary capability gaps (not keyword similarity), and requires mutual interest before any conversation starts. No cold outreach, no spam, no guesswork.
Sign up as a Founder and connect your LinkedIn or startup website. Our AI analyzes your background and what you are building, then surfaces the capability gaps your startup needs filled. You get a ranked shortlist of cofounders whose verified strengths fill exactly those gaps.
Sign up as a Cofounder. Connect your LinkedIn or GitHub so we can verify your skills. We match you with founders whose startups need exactly what you bring, whether that is engineering, operations, marketing, finance, or something else entirely.
Most platforms and networks take months of searching. Our AI gives you a ranked shortlist of genuinely complementary people from day one. Each match is scored across multiple dimensions so you can focus on the best fits first.
