What I do now

201 Ventures

I'm the General Partner of 201 Ventures, an early stage venture capital firm. We back founders that are advancing freedom and autonomy in Europe.

European Defense Investor Network

A network to organize, educate, and motivate investors in Europe to invest more in defense, intelligence, and dual-use technologies. The network also supports founders in their earliest stages of starting defense tech companies here: questions, introductions, hiring, etc.


I write about technology, investing in the national interest, and public service.

What I did before

Europe + deep tech investing

Invested at Mundi Ventures and briefly at In-Q-Tel, mostly in European and national security technology companies, respectively.

Co-founded HFDC

A non-profit emergency engineering company to re-engineer and quickly manufacture difficult-to-source PPE in California.

Engineering for national security

I built and used technology to advance US national security and foreign policy goals.


I work with my hands to design and build new products. Still do this, offline.
