Paychex
Paychex is a Rochester, New York-based provider of payroll, human resources, retirement and insurance services for small and medium-sized businesses. Founded in 1971 by Tom Golisano with $3,000, it has grown into a Fortune 500 company that pays roughly 1 in 11 U.S. private-sector workers and now embeds AI across its platforms following its 2025 acquisition of Paycor.
Cascade AI
Cascade AI is a Bellevue/Seattle-based startup building an agentic AI platform for HR and IT operations. Its AI teammates sit across systems of record like Workday, ADP, UKG and ServiceNow to answer employee questions and resolve requests across benefits, leave, compensation, policy and IT - executing workflows in real time rather than just surfacing information. Founded in 2022 by former Microsoft engineers Ana-Maria Constantin and Pulak Goyal, the company raised a $3.75M seed round led by Gradient, Google's AI-focused venture fund, and says customers see roughly a 50% drop in HR ticket volume after deployment.
Warp
Warp is an AI-native payroll, compliance, and benefits platform built for high-growth startups. It automates the back-office grind - multi-state tax registrations, filings, benefits enrollment, global contractor payments, and compliance-notice resolution - so founders can hire, onboard, and pay teams anywhere in the US and 150+ countries without the manual admin. Backed by Y Combinator and Sound Ventures, Warp has raised about $24-25M to build what it calls an autonomous back office.
Gusto
Gusto is a cloud-based payroll, benefits, and HR platform built for small and medium-sized businesses. Founded in 2011 as ZenPayroll by Josh Reeves, Tomer London, and Edward Kim, the company has grown to serve over 500,000 businesses and recently crossed $1 billion in annual revenue. Gusto handles everything from payroll runs and tax filings to health insurance, 401(k) plans, and employee onboarding - replacing what used to require a patchwork of accountants, brokers, and spreadsheets with a single platform. The company also offers Gusto Embedded, a payroll API that lets other software platforms build payroll directly into their products. Valued at roughly $9.5 billion, Gusto remains private and is widely considered a leading IPO candidate in the HR tech space.
