WHO WE ARE

We are building the next generation of staffing software. Our platform makes it faster, easier, and better for staffing companies to onboard, pay, and bill. Traditional staffing companies and tech-forward labor marketplaces use our automated, flexible, and integrated platform to reduce costs, improve worker satisfaction, and unlock new revenue streams. We onboard thousands of workers every week and orchestrate the processing of tens of thousands of paychecks per week, positioning us as critical infrastructure for workers and employers. We help our customers maintain compliance in a complex and shifting regulatory environment, and have the immense responsibility of ensuring accurate and timely payments to hard-working Americans.

Zeal is a Series B company, backed by top investors such as Y Combinator, Spark Capital (Plaid, Marqeta, Coinbase, Anthropic), and Portage. Our aim is to pioneer a new generation of software that revolutionizes the way staffing companies manage their operations and deliver world-class experiences for their employees.
