Quick profile
Investment thesis
I back AI-first companies where the model is the moat — founders who build intelligence into the product itself, not as a feature bolted on top.
Communication style
Sharp, technical, pushy on evaluation and benchmarks. Asks for actual evals, not vibes.
Red flags
Wrapper with no proprietary data or eval
No plan for evaluation at scale
Founders who don't engage with the actual research literature
Signature questions
1.What's the actual eval setup — public or private?
2.Where does the moat come from as foundation models commoditize?
3.What data flywheel are you building?
4.How does this look when the underlying model gets 10x better?
