Get a ranked shortlist from day one
No browsing hundreds of profiles. Our matching engine scores every candidate across 4 dimensions and ranks them by fit.

Get matched to the right opportunity

Social Proof
“
“I needed a technical cofounder but had no way to verify if someone could actually build what we needed. TrustedCofounder showed me exactly what each person has shipped.”
Krista K., Operations, 15+ years
“
“Every cofounder matching site is just another form to fill out. This one actually read my GitHub and understood what I bring. The matches made sense from day one.”
Aleksi E., Full-Stack Developer
“
“As a student, I thought I would have to cold-message founders on LinkedIn for months. I signed up, connected my work, and had three relevant matches the same day.”

AI Cofounder Intelligence
We analyze cofounder compatibility at a depth no human network, LinkedIn search, or forum post can achieve.
01
Real Signal Enrichment
LinkedIn experience, GitHub repos, startup websites, and writing are pulled automatically. Verifiable evidence of actual capability, not self-reported claims.
Essential for: Non-technical founders evaluating technical talent
02
Complementary Matching
Our AI matches on what your startup is missing, not keyword overlap. An operations expert sees technical founders who need their skills. A developer sees founders who need their engineering.
Essential for: Everyone. The core of what we do.
03
Blind Spot Discovery
AI surfaces capability gaps neither side has articulated. You discover what your founding team actually needs, not just what you thought you were looking for.
Essential for: First-time founders who do not know what they need
04
Both Sides Profiled
Both founder and cofounder are deeply analyzed from real work. Two-sided intelligence means both sides have confidence before the first conversation.
Essential for: Cofounders who want to know the founder is real too
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.
Connect your LinkedIn and let our AI find the technical cofounder your startup needs.
