Discover the real tech risk that's not in the pitch deck.

I help investors and founders in AI and quantum see what the technology can really do, how defensible it is, and where it creates real value for customers.

How to start

An exploratory call

Whether it's a single expert call or a full review, it starts the same way.

  1. A 20-minute call You tell me about the deal or the company and the question behind it.
  2. Scope and proposal We agree on what helps: an expert call, a full review, ongoing advisory, or a talk. You get scope and timeline up front.
  3. Findings and debrief You get my findings in the format we agreed, and we go through them with your team.

What you get is my judgment on a company's technology, team and technical risk. It is not financial or investment advice, I don't recommend buying or selling any investment, and every investment decision stays with you.

Why I stay calm when a deal gets messy: I race Ironman and Xtreme triathlon.
