Founder, Scale AI
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.
Ryan Hoover
Founder, Product Hunt
Seriously, do this today. These credits expire and once they're gone, they're gone.
Moshe Lifschitz
GP, Basement Fund
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.
Andreas Klinger
CTO, On Deck
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.
Elizabeth Weil
General Partner, Scribble Ventures
No deal with the devil, no gotcha. Dealing with the government is opaque and annoying, MainStreet makes it so companies don’t have to deal with it themselves.
Packy McCormick
Owner, Not Boring
MainStreet's relentless dedication to saving founders money – like, actual money – makes this a no-brainer for startups & us.
