About
OnPay is a bootstrapped-to-institutional software success story — an SMB payroll and HR platform that grew for 13 years without external capital before raising its first institutional round of $100 million+ in January 2025, including a $63 million Series B led by Carrick Capital Partners. The company targets the 6 million+ US small businesses that are systematically underserved by ADP and Paychex (whose platforms are designed for larger companies) and under-supported by consumer-grade tools like Gusto.
