What Mosey does

Mosey is a US-based SaaS company that automates state and local business compliance for companies operating across multiple jurisdictions. Founded in 2021 by Alex Kehayias (formerly of Stripe), the platform consolidates registration, filing, renewal, and ongoing compliance management across all 50 states and 1,000+ localities, covering payroll tax registration (withholding, unemployment insurance, paid family medical leave), entity management and registered agent services, HR compliance (labor law posters, policy generator, employee handbooks), tax nexus detection, and digital mailroom for state agency notices. The platform maintains a proprietary database of 5,000+ compliance rules with real-time legislative monitoring and integrates with 80+ payroll providers including Gusto, ADP, and Paychex.

Mosey sells through a tiered subscription model — Essential ($399/month, ≤50 employees, up to 15 states), Standard ($999/month, 50–200 employees, up to 30 states), and Advanced ($1,999/month, 200–500 employees, unlimited) — with annual prepay discounts and additional fees for registration, foreign qualification, and annual reports. Go-to-market combines a product-led self-serve motion (minutes to onboard) with customer success support for complex implementations. Customer segments span early-stage startups (Jonas Harnau, Jaques LeHot, Kenny Mendes) through enterprise (Chime, Grow Therapy, Headspace), targeting primarily multi-state and remote-first businesses with 50–200 employees.

Mosey was venture-backed by Canaan Partners, Gusto, SemperVirens, and Charge Ventures, raising approximately $21 million total (a $3M seed in March 2021 and an $18M Series A in August 2022). On April 9, 2026, the company was acquired by Gusto and is being integrated into Gusto's payroll and HR platform as 'Gusto Business Compliance,' expected to launch later in 2026 and extend compliance automation to Gusto's 400,000+ small business customer base.

Direct peers

• Harbor Compliance: Harbor Compliance is a direct competitor offering state and local compliance services including registered agent, entity management, annual reports, and business licensing across all 50 states. It targets the same mid-market and growth-stage customers as Mosey with a similar software-plus-services model.
• CSC (Corporation Service Company): CSC is a leading provider of registered agent, entity compliance, and governance services for businesses globally. It competes directly with Mosey on Secretary of State compliance, foreign qualification, and annual reporting, particularly for larger enterprises.
• Mineral (formerly ThinkHR): Mineral provides HR compliance content, policy libraries, and tooling to help employers navigate federal and state labor laws. It overlaps with Mosey's HR compliance module (policy generator, labor law posters, handbook updates) and serves similar HR and people-ops buyers.

Broad incumbents

• Rippling: Rippling is a broad HR, payroll, and IT platform that increasingly bundles state and local compliance features for multi-state employers. It targets similar multi-state SMB and mid-market customers but offers compliance as part of a much wider HRIS suite rather than as a focused compliance product.
• Deel: Deel is a global EOR and payroll platform that handles international and US employment compliance. While primarily focused on international hiring, its US compliance capabilities compete for multi-state employer wallet share that overlaps with Mosey's target use cases.
• Trinet (TriNet): TriNet is a PEO that bundles payroll, benefits, and HR compliance for SMBs. It competes directly with Mosey's value proposition of outsourcing compliance complexity, and is explicitly referenced in Mosey's own PEO Transition Guide content.
• Insperity: Insperity is a PEO providing co-employment, HR administration, and benefits management. It is a comparable substitute for Mosey at the mid-market tier, bundling many compliance functions inside its PEO relationship.
• Avalara: Avalara is a leading tax compliance automation platform covering sales tax, VAT, and corporate income tax nexus. It overlaps with Mosey's tax compliance and nexus detection modules and competes for the tax-side of multi-state compliance spend.
• ADP: ADP is the largest US payroll and HR services provider, offering multi-state payroll tax registration, compliance services, and HR administration. It is both a Mosey integration partner and a potential bundling competitor for compliance automation.

Emerging players

• Multiplier: Multiplier is an EOR platform expanding into US state-level compliance and entity management for employers hiring across states. It targets similar multi-state employers but is primarily an EOR first, with compliance automation as an adjacent capability.
