We are a modern, embedded payroll provider that helps empower companies to build their own unique payroll service. On top of our easy-to-use payroll API, we are pioneering an all-inclusive tax engine to democratize a broken and cumbersome process providing accessibility to small, medium, and large businesses and helping Americans get paid.

Backed by over $14 million in funding by top investors such as Y Combinator, Spark Capital (Marqeta, Coinbase, Affirm), and Robinhood's Founder; Vlad Tenev we are projected to be a forerunner in embedded payroll with an industry amassing billions of dollars in untapped revenue.

Our mission is to empower companies to become their own fin-tech company using our simple, seamless, and forward-thinking payroll technology and we'd love to learn more about you and how you could be a fit for our growing team!
