Salsa, a leading provider of embedded payroll infrastructure, has raised $20 million in a Series A funding round led by Altos Ventures, further accelerating its mission to simplify payroll integration for software platforms.

The funding round also saw participation from prominent investors including Greycroft, SemperVirens, Definition, and Better Tomorrow Ventures, bringing Salsa’s total funding to $30 million to date.

Salsa’s platform empowers software companies to swiftly build, launch, and manage fully integrated payroll solutions within weeks. By managing complex processes such as worker onboarding, compliance reporting, and tax filings, Salsa eliminates the need for businesses to maintain in-house payroll expertise or invest heavily in operational resources.

The company’s growth trajectory has been remarkable — expanding more than tenfold in 2024 and doubling again in the early months of 2025. Salsa now supports payroll operations across all 50 U.S. states and Canada, marking a significant milestone in its expansion efforts.

“We built Salsa to keep the operational burden off our partners’ shoulders, so they can focus on what they do best,” said John Kramer, CEO of Salsa. “This funding lets us double down on automation, flexibility, and deep support in industries where payroll is hardest to get right.”

The investment will be channeled into enhancing Salsa’s compliance automation, regulatory reporting, and governance capabilities — critical components in today’s rapidly evolving regulatory environment. As businesses face increasing regulatory requirements surrounding payroll management, solutions like Salsa offer a compelling value proposition, combining embedded finance with robust compliance management and operational efficiency.

With its focus on automating complex payroll workflows and providing scalable solutions, Salsa continues to set a benchmark in the RegTech and fintech sectors, particularly in areas like regulatory technology solutions, compliance software, and risk mitigation strategies.
