AskLeo
Built by a VC. For founders.

The VC feedback most founders never get.

AskLeo helps you stress-test your idea and pitch deck before you talk to investors.

  • Private by default — your data is never shared with third parties
  • Built on a VC framework — years of investing experience
  • Deep-tech focused — science, AI, hard tech

AskLeo is an AI tool built on Leo's investment framework. It is not a substitute for direct VC feedback.

Most first-time founders get feedback too late — after they've already pitched and been rejected. By then, the market sizing was wrong, the competition slide missed the point, and the team story didn't land. AskLeo asks the hard questions before you pitch.

Leo Cui, PhD, CFA
GP at FoundersX Ventures

I have a PhD in Bioengineering from Harvard and did my postdoc at MIT Broad Institute. I'm a General Partner at FoundersX Ventures, an AI and deep-tech VC fund, with 10 papers, 6 patents, two research projects that led to startups, and one technology licensed to Quanterix (NASDAQ: QTRX). I'm a founding leadership member of Nucleate.

A lot of first-time founders and students have reached out asking for feedback on their ideas. I can't always respond to everyone — so I built this instead. Still a work in progress.
