Early-Stage Investor

Backing founders
before the world
knows their name.

Where conviction
meets capital.

Ark Reactor is an early-stage investment vehicle focused on transformative technology — specifically the intersection of artificial intelligence, spatial computing, and immersive media.

We look for founders with deep technical conviction and a clear sense of who their technology is for. We move fast, stay hands-on when it helps, and back ideas that most investors aren't ready to touch yet.
