Justworks is a technology platform providing payroll, benefits administration, and compliance infrastructure to small businesses through PEO and EOR solutions across all 50 U.S. states.
Justworks builds the payroll, benefits, and compliance infrastructure that small businesses would otherwise need enterprise resources to obtain. Founded in 2012 by Isaac Oates after he encountered the complexity of HR administration firsthand, the company operates a technology platform spanning payroll technology, compliance automation, and benefits administration, delivered through Professional Employer Organization (PEO) and Employer of Record (EOR) models.
The engineering work is substantial in scope. The platform handles payroll taxes and compliance requirements across all 50 U.S. states, where regulation varies by jurisdiction and error carries real consequences for employers and their staff. Thousands of small businesses rely on it. The technical domains at play include payroll technology, compliance automation, benefits administration technology, and the HR platform systems underpinning PEO and EOR delivery.
Products include a PEO solution granting small businesses access to enterprise-grade payroll, benefits, and compliance infrastructure; an EOR solution handling payroll taxes, compliance requirements, and benefits administration; and the underlying payroll and compliance technology platform itself. The company's stated aim is to make starting, running, and joining a business accessible regardless of size or resources, and to level the playing field between small businesses and larger competitors.
