Gusto has acquired Mosey, an AI-powered business compliance platform, in a bid to bring end-to-end compliance management directly into its existing platform.
The acquisition is aimed at addressing one of the most persistent barriers to small business growth: regulatory compliance. No deal value was disclosed. With Mosey integrated into its platform, Gusto will offer more than 400,000 small businesses state and local registration, filing, renewal and ongoing compliance management in a single location — eliminating the need for separate tools or third-party integrations.
Gusto’s platform is designed to help small businesses manage payroll, benefits and HR in one place. The company serves more than 400,000 small businesses across the United States, helping them hire and pay their teams while navigating the administrative complexity that comes with building a workforce.
Mosey is an AI-powered compliance platform built specifically for small businesses. It was founded by Alex Kehayias after he experienced firsthand the compliance pitfalls that face new business owners — from hiring without the correct legal setup and incorrect payroll configuration to missed tax deadlines. The platform was built to answer the question every new business owner faces after incorporation: “What do I do next?”
The acquisition comes as compliance costs continue to mount for small businesses. Businesses with fewer than 50 employees face roughly $14,700 per employee per year in compliance costs — approximately 20% more than large enterprises with dedicated legal teams. Fifty-one percent of small business owners say compliance negatively affects their growth.
The compliance burden compounds quickly. Each new hire in a new state can trigger unemployment insurance registrations, workers’ compensation requirements, paid family leave filings, corporate and franchise tax obligations, and Secretary of State registration requirements — often across multiple agencies. Mandatory benefits and state-specific policies continue to expand: California already requires employers to offer retirement plans, and Maryland added a similar requirement in 2026. Roughly 15,000 new laws are passed across all levels of government every year, with notifications often sent to physical addresses businesses no longer staff.
With Mosey’s technology and team now integrated into Gusto, the combined platform will expand beyond HR and payroll to include state and local business registrations, entity management, ongoing filings and renewals, resolution of agency mail, and real-time surfacing of new compliance obligations as businesses grow or expand into new states.
The new offering, to be called Gusto Business Compliance, is expected to launch later this year. It will use AI to automate compliance complexity in the background, requiring no separate tool, no integration to maintain and no compliance expertise from the business owner.
Gusto co-founder and chief product officer Tomer London said, “Building a business is hard enough without compliance getting in the way. With Mosey now part of Gusto, we can do what Gusto has always done: take complexity off the plate of small business owners so they can focus on what they actually started their business to do. This is a natural extension of our vision to be the platform that helps small businesses start, hire, and grow.”
Mosey founder Alex Kehayias said, “I started Mosey because I’d made every compliance mistake myself, and then I watched thousands of other businesses make the same ones. The problem isn’t that small business owners don’t care about compliance, it’s that they shouldn’t have to become experts in it. Joining Gusto means we can bring that vision to the millions of small businesses that need it most.”
