In the crowded fintech landscape, Check isn't building another payroll app—it's building the infrastructure that powers payroll inside the apps you already use. By turning SaaS platforms into payroll providers, Check is solving the 'last mile' problem of the $60B payroll industry.

"Check isn't competing with ADP—they're making ADP obsolete by turning every vertical SaaS platform into a payroll processor."

The competitive moat isn't just technology—it's compliance. Payroll involves tax filings, benefits, and regulatory complexity across all 50 states. Check handles this complexity so platforms can focus on their core product. Their tech stack (jQuery, Tailwind, Vite) suggests a mature but pragmatic engineering culture, prioritizing reliability over bleeding-edge frameworks.

• API-first architecture lets platforms embed payroll in 3-6 months, not 3 years
• Revenue share model aligns incentives: platforms earn while Check handles infrastructure
• Direct traffic (59%) indicates strong brand recognition among technical buyers
• Top keywords include 'check console' (70 monthly)—showing active developer engagement
