From 80% Vibe Coded Prototype to 100% Launch-Ready Product
Code and learn the last 20% alongside a seasoned builder at the Pirin.ai Founder Builder Studio. Cross the finish line with confidence, ownership, and deep understanding of your product. Don't get stuck searching for a technical co-founder (the good ones are busy building)—launch independently now and find the right long-term match on your own terms.
Why We Exist
Solving the technical co-founder problem for ambitious founders
One of the most common questions in Founder Institute mentor hours: "Where do I find a technical co-founder?" The painful truth? The good ones are already building their own startups.
This leaves ambitious founders with two bad options: hire agencies incentivized by billing hours (not your success), or build alone with AI tools. While AI has made 80% prototypes possible, that final 20% to ship a solid product still requires real technical depth.
Pirin.ai is a Founder Builder Studio that aims to bridge this gap. We help you push through the final 20%, launch with confidence, and control your destiny. Stop waiting for the perfect co-founder. Start building.
To be clear, AI doesn't replace technical experts—it makes them superhuman. But you're better off in-market learning and iterating than sitting on the sidelines. Launch now. Find the right co-founder/CTO later, on your own terms.
