Payroll API for embedded SaaS and HR platforms

Software Development New York, NY 51–200 employees Founded 2019 Privately Held

Check builds a payroll-as-a-service API designed to be embedded into vertical SaaS, HR, and time-tracking platforms. The stack is Python + Django + React on AWS with PostgreSQL, suggesting a monolithic, operator-friendly architecture. Project list reveals heavy investment in tax compliance (systemic tax notice fixes, trend analysis, SOP refinement) and platform reliability (architecture simplification, CI/CD improvements, infrastructure scaling), while pain-point clustering around 'broken payroll team' and 'complex payroll workflows' indicates the company is stabilizing core product and operational maturity rather than exploring adjacent markets.
