Inspiration
I kept seeing people with great ideas but no one to build with. Cofounder mismatch is a top reason startups fail, and finding the right partner still comes down to luck or networking events. I wanted to use AI to make that process smarter.
What it does
Cofounder Connections matches aspiring founders based on skills, interests, and what they're looking for in a cofounder. Users create a profile and the platform surfaces complementary matches they can connect with directly.
How we built it
I built the frontend with Next.js and Tailwind CSS, and used Supabase for auth, database, and file storage. The matching logic is tag-based. For search, I set up a ReAct multi-agent architecture using Claude Haiku for fast retrieval and Sonnet for deeper reasoning.
Challenges we ran into
Getting the matching to feel useful and not just surface-level keyword overlap took a lot of iteration. I also spent time making sure the multi-agent search pipeline didn't hallucinate or return bad results. Keeping the UI consistent while building fast was another constant battle.
Accomplishments that we're proud of
I shipped a working MVP with real AI-powered matching, not just a concept. The multi-agent search works end to end. I built a clean profile system with photo uploads. The project is also backed by the 49er Foundry CoLab program at UNC Charlotte which gave it real validation early on.
What I learned
Prompting-only architectures can do a lot when you design them carefully. I also got way better at understanding how multi-agent coordination works in practice. On the product side, I learned that you need to define what compatibility actually means before you write any matching logic.
What's next for Cofounder_Connection
I want to add personality and behavior-based signals to the matching. I also want to add an education layer to help founders who struggle to find the right resources, that will also help me get organic traction on my account. The educational layer is meant to make founders understand the importance of right communication that is needed to stay aligned with people.
