James Lindenbaum
AcceleratorFounding Partner, Heavybit
Heroku co-founder, dev-tools fund pioneer
Background
James Lindenbaum co-founded Heroku, the pioneering cloud platform-as-a-service, and after its acquisition by Salesforce he founded Heavybit in 2013 to fill a gap he experienced firsthand: helping developer-tool companies navigate go-to-market challenges. Heavybit is the only fund focused exclusively on developer-company GTM, investing in pre-seed and seed stage infrastructure and developer-tools startups globally. He champions a bottoms-up enterprise adoption model where tools sell through developers rather than to CIOs. Notable Heavybit portfolio companies include Snyk, LaunchDarkly, Netlify, CircleCI, and Tailscale.
