Prasanna Sankar was a director of engineering at Zenefits. When Parker Conrad resigned in February 2016, Sankar reached out to him, and the two founded Rippling that year.
Before Zenefits he was co-founder and CTO of LikeALittle, a social app that reached two million users in six weeks. He is also a former competitive programmer, ranked first in India on TopCoder.
The company spent two years in stealth, working from Conrad's San Francisco home. In March 2023 it raised about $500M after the Silicon Valley Bank failure froze customer payrolls.
Rippling reached a $16.8B valuation in May 2025 with a $450M Series G.
