We owe our success to the strength of our team, and our benefits reflect that.

In-Home “Office” Perks

We’re a remote-first company, fully distributed across 30+ states and Canada. And we just opened our first in-person office in San Jose!

Company Outings

We come together at least once a year to celebrate our wins, build in-person relationships, and look to what’s next.

Our Values

Company culture requires commitment.

We work every day to live up to what we value most.

We won’t stop until we’ve helped every small business.

We come to work because we believe that we can fundamentally reshape America’s economic landscape. We pursue big bets in service of our customers, and when we hit headwinds we find a path forward.

We’re a backyard BBQ kind of company.

Our team spans 30+ states and Canada. We’re an ecosystem of entrepreneurs working to promote a strong community and produce great work.

We are responsible for the team’s success.

Integrity, respect, and trust form the bottom line – we know that we can’t succeed if we don’t do what is right every. single. time. We’re humble as individuals so that we can accomplish great things together.

We trust you to do you.

We work hard, but not at the expense of everything else in life. We’re each trusted to do what’s best for us, our team, and for MainStreet. We prioritize relentlessly and support each other’s boundaries so we can all do our best work sustainably.

We move as fast as our customers do.

We set “impossible” goals, test new ideas, and support our people to take smart risks. We deliver results quickly, invite feedback, and continuously iterate to co-create the best version of everything we build.
