What We’re Looking For

Must-haves

• 0→1 product experience at a high-growth B2B company
• Proven track record shipping AI-native products where AI is core to the experience
• Deep fluency in AI and LLMs — understands how to build and ship with them

Nice-to-haves

• Familiarity with AI evaluation systems
• Technical fluency — coding not required, but comfort building with AI agents matters

This is for you if…

You’ve helped scale a B2B product from Series A to Series C and want to do it again. You thrive taking ambiguous problems from zero to a working product in users’ hands. You want direct ownership over a commercial product with real revenue implications.

This is not for you if…

You prefer a defined roadmap over building one from scratch. You’re not comfortable working closely with AI tools and systems as core product components. You need clear separation between PM work and commercial strategy
