Investing in AI, defense, hardware and manufacturing.

I invest in early-stage technology companies focused on national security.

I was a Partner at Buckley Ventures from 2021-2025 and led the firm's investments in AI, defense, and hardware. During my tenure, the firm scaled assets from $62M to $1.5B as a two-person investment team.

Before investing, I worked on data centers & networking at Meta, small satellite avionics at NASA, AI research at SPC and software engineering at three exited startups.
