Check Technologies (Check) is a Stripe-incubated embedded-payroll infrastructure company whose API lets vertical SaaS, HR, and time-tracking platforms embed full-service payroll directly into their own products. The Check API handles the hard parts of running payroll — worker onboarding, pay schedules, earnings and deductions, tax calculation, filing and remittance across federal, state, and local jurisdictions, contractor payments, and money movement — behind a white-labeled, developer-first surface. Platforms integrate through the REST API, embeddable white-labeled React Components (Company Onboard, Run Payroll, W-4 / tax setup, bank connection via Plaid, filing authorization), webhooks, a Model Context Protocol server for AI agents, and a Python CLI. Check is backed by Stripe, Index Ventures, Thrive Capital, Bedrock Capital, and Battery Ventures, and powers payroll for platforms including Homebase.
