Banking for what you're building.

Mercury is a banking platform built for startups who need the basics to business banking. With our partnership, Firstbase founders can now set up banking, corporate cards, payroll, benefits, and more before receiving their Employee Identification Number (EIN).

Banking is the backbone of every business, so we’re excited to help more founders launch at scale by enabling them to open a bank account on their terms.

Thank you for getting the company set up super fast. I think it happened efficiently. The team is there to email if you have questions too. The dashboard accurately displays what is completed and what to expect.

Incredible Service. This was a fast, easy, hassle-free experience, I won't say it matched my expectations, NO, It exceeded my expectations and amazed me. They're the best of the best. So happy that I chose Firstbase and confident I'll make another round for another venture.

Wow, @tryfirstbase is really fantastic. Set up the corp, EIN, registered agent, bank account through/via them and 1.5 months later I'm way more organized than I ever was.
