Salsa, a startup delivering embedded payroll infrastructure, has raised $20 million in a Series A round led by Altos Ventures. The latest round also saw participation from Greycroft, SemperVirens, Definition, and Better Tomorrow Ventures, bringing the company’s total funding to $30 million.
Salsa’s platform allows software companies to rapidly build and launch fully integrated payroll offerings—without needing internal payroll expertise or large back-office teams. From onboarding and payments to tax filings, Salsa manages the entire backend, allowing clients to focus on user experience and growth.
The company experienced explosive growth in 2024, increasing revenue more than tenfold and doubling again in early 2025. Its infrastructure now powers payroll products across all 50 US states and in Canada, supporting a range of vertical SaaS and platform-based businesses.
John Kramer, CEO of Salsa, stated: “We built Salsa to keep the operational burden off our partners’ shoulders, so they can focus on what they do best. This funding lets us double down on automation, flexibility, and deep support in industries where payroll is hardest to get right.”
With fresh capital in hand, Salsa aims to further automate the complex workflows involved in payroll and deepen its product offering in underserved and highly regulated industries.
