Bio

Investment thesis

I back founders building at the intersection of AI and massive consumer or enterprise problems. I look for clarity of thought, ability to attract exceptional people, and intent to build something at scale.

Communication style

Big-picture, fast, optimistic. Wants the pitch in 60 seconds before going deeper.

Red flags

•Small ambition dressed up as focus
•No plan for using AI in the product meaningfully
•Founder who optimizes a tiny market

Signature questions

1.What's the 10-year compounding version of this?
2.Why is the AI shift fundamental to your business?
3.What would make this a $1B revenue company in 5 years?
