PracticeThree ways I work

Advise, build, invest.

All three come out of a career in security.

AI strategy and transformation

A senior partner for your AI plans, without the hype.

I work out where AI fits in your business, what to do first, and how to roll it out safely. I also work as a fractional CTO, and help teams show how their AI is used and who controls it.

Build to production

Built the way a security team would build it.

Secure cloud architecture and backends come first. AI agents and private search over your own data come next, when the job needs them. I built challenge labs and red-team environments for a cybersecurity company, and I treat every client build as a security problem from day one.

Invest as an operator

A few careful bets on software and infrastructure.

I back early-stage companies where the build still matters, and I stay hands-on in the build.
