Half the American workforce works at a small business, and most of those businesses cant afford a real HR team When they hit an HR decision they dont have the expertise for — a termination, a comp change, setting a time-off policy for the first time — they either pay for expensive outside help or guess, even though the right answer depends on rules that vary across 50 states and hundreds of localities

HR Experience is building that expertise directly into Gusto: compliant HR guidance and documentation, built natively for both the employer creating it and the employee receiving it, in a domain where the compliance bar is real — "mostly right" isnt good enough.

Youll also help drive the other half of HR Experiences mission: using AI to make Gustos human HR Partners faster and more effective, so more small businesses can get real HR support without needing to hire their own HR team.
