Ex-YC Founder

• This is a full-time, in-person role based in San Francisco (Presidio) - we work from the office 5 days a week.

• You must be based in the Bay Area or willing to relocate before starting.

• We require US work authorisation, but are open to O-1 or J-1 visa sponsorship for exceptional candidates.
  

Something didn't work out. We get it. Some YC companies don't end the way the founders pictured, but the people who come out of that experience are some of the sharpest operators we know. We're looking for founders who still have the fire and want to plug into something that's past zero-to-one but still wide open.

We're 15 people defining a new category: our main product, Sauna, is the first multiplayer AI brain. You'd be one of the first people showing the world what Sauna can do in a team where your work actually moves the company.

• Ran a YC company

• Know exactly what worked and what didn't

• Still want to build something massive rather than settle into a comfortable role

• Wear multiple hats

• Are genuinely excited about AI agents, not just resume-excited

Shape is flexible. We've hired past founders into engineering, product, and growth roles. Tell us where you're strongest and we'll build the scope around you.

We're backed by Spark Capital, Felicis, Y Combinator, Day One Ventures, and angels including Paul Graham, Vlad Magdalin (Webflow), Mathilde Collin (Front), and Paul Daugherty (Accenture). We raised $30M and we still work like a seed startup.
