Investment Thesis

Heavybit is the leading early-stage investor in enterprise infrastructure, with an unrivaled track record of helping technical founders achieve breakout success since 2013. The firm believes in backing unique founders with transformative visions who are redefining how teams build, deploy, secure, and scale enterprise software. They invest from Day 0 with high conviction, committing to founders before the broader market recognizes their potential.
