Ryan Hoover
Founder, Product Hunt
MainStreet is a no-brainer for any startup. Free cash is certainly a strong value prop, there's no reason not to onboard and let them save you money.
Lucy Guo
Founder, Scale AI 🦄
Any founder I meet, the first thing I tell them: sign up for MainStreet. It's the easiest money you'll ever find.
Lukas Wagner
VP of Finance, Pipe
Government incentives are complex. Working with MainStreet is not. Flawless customer experience, they even did all of the paperwork for us to claim our credits.
Elizabeth Weil
Founder, Scribble VC
I wish we'd had MainStreet at Twitter in the early days. We barely had the time to think, let alone learn about tax codes.
Andreas Klinger
Advisor, On Deck
Between Product Hunt, AngelList, On Deck, and Remote First Capital, I've met with thousands of founders. It's shocking how few are claiming these credits.

We've saved startups millions.
