Supporting builders at the AI + software frontier, and collecting hobbies on the side.

Where I share projects, notes, and the occasional half-baked idea — as I learn, build, and challenge myself.

about

Alex Tran

Investing in AI infra, software, and physical AI

I invest in early- and growth-stage companies building the infrastructure behind software and the physical world.

Before CapitalG, I advised technology companies and investors at McKinsey, with earlier stops at Snackpass, Lucid Motors, Cisco, and Morgan Stanley. I studied Business Administration and Economics at UC Berkeley.

Outside work, I collect hobbies — currently basketball, cycling, and writing The Sixth Source.

I also have nearly 100 first cousins. Growing up in a large Vietnamese immigrant family taught me that community is built by showing up for people, and that trust compounds over decades. That lesson shapes how I invest and build relationships.
