Gusto crosses $1B in trailing revenue, eyes IPO and new products for solo founders

Gusto crossed $1 billion in trailing twelve-month revenue a few months ago, a figure Joshua Reeves is deliberately precise about. Trailing revenue, not ARR extrapolated from a recent quarter — a distinction that signals the business is generating that run rate across the full year, not projecting forward from a peak month.

Reeves says the company has been free cash flow positive for several years and reinvests that cash into product rather than burning it to grow. The addressable market he points to is 6 million employers in America, roughly two thirds of which have fewer than five employees.

IPO

An IPO is coming, but not soon. Reeves says he would not expect Gusto to stay private "in the near term," stopping short of any timeline, and says the process hasn't started. He frames the current focus as execution through an AI transition rather than market timing.

“We passed, actually a few months back, a billion dollars of trailing revenue... I would not expect Gusto to be private in the near term... We acquired Mozy to help with expanding our work around business compliance. Things that we maybe thought of as the next two to three years, I now think of as the next three to six months.”

Solo founders and new products

Gusto's expansion into pre-employer businesses is the more forward-looking piece. A product called Gusto Solo targets founders who need to pay themselves before they hire anyone, covering the specific tax treatment and compliance requirements that apply to one-person companies. Gusto also acquired Mozy to extend its compliance capabilities for that segment. Reeves says several additional products aimed at businesses before they become employers are coming in the next few months, and he explicitly pulls forward what he previously thought of as a two-to-three-year product roadmap into a three-to-six-month window.

Labor market read

On hiring, Reeves describes small business hiring across Gusto's customer base as "more depressed" over the last few years relative to the prior decade, which he partly attributes to AI's effect on company growth rates. New business formation is moving the other way — accelerating, showing up in both Gusto's internal data and third-party sources. His read is that AI is pulling more people toward starting businesses rather than staying in employment, which he calls the "happy path."

AI inside Gusto

Reeves draws a clear internal line between where LLMs are useful and where they aren't. Most of Gusto's ongoing back-end systems, including payroll processing, run on deterministic logic where accuracy requirements make large language models a poor fit. LLMs become more useful where judgment calls are involved — risk assessment, ambiguous inputs, edge cases. On the build side, he says AI is compressing development timelines dramatically, letting smaller teams iterate faster across both new features and existing product surface area. The constraint he flags is that rebuilding an existing codebase while running it at scale is inherently more complex than greenfield development — "rebuilding the train, running the train, accelerating the train, laying the tracks, all in parallel."

Word-of-mouth, including from employees who were paid through Gusto at a previous job and then chose it when starting their own company, remains the primary growth driver.
