We build things worth finishing.

Greenfox Ventures LLC is a Connecticut-based studio. Small team, deliberate craft, no venture runway to burn — just software we'd want to use ourselves.

Founder

Alex Furer has spent nearly two decades in finance leadership roles at technology companies, working closely with product and engineering teams to turn complex systems into businesses that scale. Greenfox Ventures is a return to building directly — less strategy deck, more shipped software.

Cavernum started from a familiar itch: playing puzzle games that were too easy to stay interesting, and wanting to see how hard the genre could actually get without losing what makes it satisfying.
