About

The Holding

Rex Machina is a personal investment holding company investing directly into startups—no fund structure, no LPs, no committees. Just fast decisions and full alignment with founders.

We only invest in founders we already know. No pitches, no cold outreach. Our best investments come from relationships built over years of working together in the trenches.

Currently closed for new investments. With 2026 shaping up well, we may consider new opportunities in 2027.
