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.
The Actual OpportunityWe'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.
You Probably…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.
P.S.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.

What We Do
Sauna is an AI agent designed to learn how individuals and teams work, remembering critical information and acting on their behalf. By connecting to tools like email, calendar, and messaging, it helps manage tasks and workflows automatically, allowing work to move forward even when the user is offline. It effectively serves as an AI-powered workspace and coworkers' assistant.
