About Sol

Sol is an agentic HR system built for how work is changing. We're replacing the traditional HRIS with an AI-native foundation. We are built for change, designed to scale, and reimagined with AI from the ground up, so HR leaders get a clear view of their workforce instead of a system everyone works around.

At Sol, we're guided by three things: people: we hire driven, humble people and build to amplify their potential and our customers'; imagination: we challenge assumptions about our industry and how software gets built, then move fast once we've decided; and durability: we sweat the details to build a company that is meant to last. Day to day, that shows up as a bias toward writing things down over meetings, async communication by default, and flexible hours that respect how differently everyone works. We try new things, kill what isn't working, and hold a high bar without the politics or ego that slow good decisions down.

Sol was founded by leaders who spent decades building the modern HR category, and is backed by Sutter Hill Ventures and NEA. Our first customers go live in early 2027 and we need you to make them wildly successful.
