Gusto

Gusto is the payroll, HR, and benefits software company discussed in Gusto Co-Founders: Josh Reeves, Edward Kim & Tomer London through its co-founders Josh Reeves, Eddie Kim / Edward Kim, and Tomer London. The company began as ZenPayroll after the founders moved away from a weaker marketplace-services idea during the Y Combinator process and focused on making small-business payroll easier, more reliable, and more human.

The source makes Gusto a case in Payroll Infrastructure Trust. Payroll is mandatory, sensitive, and hard to beta casually because employees, taxes, filings, and benefits depend on correctness. Gusto’s first wedge was deliberately narrow through Regulated Workflow Wedge, then expanded from salaried California payroll into hourly workers, contractors, more states, benefits, time tracking, tax credits, international hiring, and a broader Entrepreneurship Infrastructure ambition.

Gusto also matters as a founder-team case. The three founders kept explicit roles, with Josh as CEO, Eddie as CTO, and Tomer as chief product officer, then used recurring feedback walks and values-driven hiring to maintain Co-Founder Relationship Maintenance as the company grew.
