The Engineer with an Idea
You've built systems at scale but never built a company. You have the technical chops — what you need is someone who speaks customers, fundraising, and go-to-market.
You'll recognize this if…
- 01Side projects that never found users
- 02Strong opinions on architecture, weaker on distribution
- 03Ready to go full-time once the right partner appears
You've built systems at scale but never built a company. You have the technical chops — what you need is someone who speaks customers, fundraising, and go-to-market.
Signals
- 01Side projects that never found users
- 02Strong opinions on architecture, weaker on distribution
- 03Ready to go full-time once the right partner appears
You've run teams, closed deals, or scaled operations. You see market gaps everywhere but need a technical co-founder to turn vision into product.
Signals
- 01Validated an idea but can't build the MVP
- 02Deep domain network waiting to be activated
- 03Fundraising-ready with a deck but no prototype
Years in healthcare, fintech, logistics, or another vertical gave you insights outsiders can't Google. You know exactly what's broken — you need a builder.
Signals
- 01"Why hasn't anyone fixed this?" is your catchphrase
- 02Rolodex of future design partners and first customers
- 03Regulatory and compliance knowledge that takes years to earn
You've done this before — maybe exited, maybe failed, definitely learned. This time you want to start with the right co-founder instead of settling.
Signals
- 01Previous startup experience, successful or not
- 02Clear thesis on what went wrong last time
- 03Moving fast and filtering for complementary strengths
No startup on your resume yet, but the ambition is real. You're learning fast, building in public, and looking for someone equally hungry to take the leap.
Signals
- 01Consuming every podcast, blog, and Y Combinator video
- 02Experimenting with ideas nights and weekends
- 03Looking for an accountability partner as much as a co-founder
Optimized for job seekers, not co-founders.
EVENTS
One evening, one city, surface-level conversations.

Great for takes. Terrible for finding who's actually building.
ACCELERATORS
Require a team to apply. Chicken-and-egg problem.
