About

Angel investor and advisor backing early-stage startups in developer tools, infrastructure, and fintech. Currently leading business development at a global technology company. Based in Chicago.

What I Do

Investing

Angel checks into early-stage startups building developer tools, infrastructure, and fintech products.

Advising

Helping founders navigate go-to-market, partnerships, and enterprise sales from zero to one.

Operating

Building and scaling business development at the intersection of technology and global markets.

Investment Thesis

I back pre-seed and seed founders building the infrastructure layer -- developer tools, API platforms, and fintech plumbing that other companies build on top of. I look for technical founders solving real problems with clear distribution advantages, not hype cycles.
