Frequently asked questions

Who runs investment decisions at Heavybit?

Tom Drummond and Dana Oshiro lead the partnership. Drummond serves as Managing Partner and Oshiro as General Partner. The firm does not disclose a formal investment committee structure, but public record indicates the two principals make final call decisions jointly, supported by a network of operator-advisors from Stripe, GitHub, and Docker.

Does Heavybit invest outside of developer-tools companies?

No. Heavybit's mandate is constrained to companies selling software to engineers — including developer tools, API platforms, cloud infrastructure, and open-source commercialization. The firm has not made a consumer or general enterprise SaaS investment outside this developer-first thesis since its 2013 founding.

What investment stages does Heavybit typically target?

Heavybit writes Seed and pre-Seed checks almost exclusively. The firm positions itself as a first-check investor and maintains a structured advisory program to help founding teams reach Series A. There is no public record of Heavybit leading later-stage rounds.

How does Heavybit source proprietary deal flow?

The firm's primary sourcing channel is a curated network of operator-advisors drawn from engineering leadership at Stripe, Twilio, GitHub, and Docker. These advisors often refer pre-launch teams from within their own organizations. Heavybit supplements this with private developer conferences and founder circles that surface early-stage projects before they hit generalist funds.

Does Heavybit participate in fund commitments or only direct deals?

Heavybit operates as a direct-investment vehicle. The firm writes equity checks into portfolio companies and does not publicly disclose fund-of-funds commitments or LP positions in other venture firms.

Which sectors does Heavybit explicitly avoid?

Heavybit avoids consumer internet, hardware, biotech, climate, and any company whose primary buyer is a non-technical business function. The firm's publicly stated thesis excludes any market where the end user is not an engineer or developer team.

Is Heavybit structured as a traditional venture firm?

Heavybit operates a standard venture capital fund structure with limited partners, but layers a dedicated operator-advisor platform on top that no traditional venture firm runs at equivalent depth. Portfolio founders gain access to go-to-market workshops, private events, and a network of practicing engineering executives that functions as a proprietary value-add mechanism.
