About Check

Payroll is broken. It's still running on decades-old infrastructure. We're rebuilding it.

We don't run payroll ourselves — we power the businesses that do. As the inventors of embedded payroll, we're redefining how people get paid and making it easier for those businesses to launch, grow, and thrive.

On our team, you'll use creative problem-solving, critical thinking, and grit to simplify the complexity of payroll for thousands of employers of every size, across all industries. We ignore conventional role boundaries in favor of the unique strengths and values each builder brings to our mission: make paying people simple . Check out our origin story!

Check is far more than just API infrastructure. We’re a springboard for building and scaling payroll businesses. See how it works for our partners.
