Acadia HR

What Acadia HR does

Acadia HR is a privately held Professional Employer Organization (PEO) founded in 1989 by Jim Belliveau in Red Hook, New York, providing outsourced human resources, payroll, benefits administration, compliance, and time management services to small and medium-sized businesses across the United States. The company operates as a co-employer, taking on administrative employer responsibilities while clients retain operational control of their workforce. Its core technology is the proprietary Acadia Online platform, a secure cloud-based portal providing 24/7 access to payroll invoices, employee pay, benefits history, W-2s, HRIS data, time and attendance records, and custom reports, with an integrated web-based Time Management System (TMS) that exports hours directly into payroll processing.

The company was originally built to serve building trade sub-contractors in the Hudson Valley region and has since expanded into a full-scale national PEO serving clients across industries including nonprofits. Acadia HR's product portfolio comprises five integrated service lines — Payroll & Time Management, Human Resources Management, Benefits Administration, Compliance Services, and the overarching PEO offering — all delivered through the Acadia Online platform. The company maintains retained counsel from Jackson Lewis, P.C. (a major employer-side labor law firm) and has built multi-redundant business continuity infrastructure with offsite data storage.

Acadia HR is family-owned and bootstrapped, with CEO Anna Belliveau and founder/President Jim Belliveau at the helm alongside a small internal team of approximately 1-10 employees (per firmographic data). The company generates revenue primarily through recurring service fees bundled with payroll processing, supplemented by professional services for HR management and managed services for benefits administration. Pricing is quote-based and not publicly disclosed. Go-to-market is sales-led and relationship-driven, combining direct website inquiry, toll-free and regional phone outreach, and personalized consultation, with content marketing via a senior HR consultant's blog as a top-of-funnel thought leadership channel. The company operates from three offices (Red Hook NY, Austin TX, Nashville TN) and serves clients nationally with a concentration in the Hudson Valley.

• Vensure Employer Services: Privately held national PEO/HR outsourcing firm offering co-employment, payroll and benefits administration to SMBs—directly comparable operating model and customer segment.
• Gusto: Full-service payroll, benefits and HR platform built for small businesses with bundled PEO capabilities—overlaps with Acadia's payroll, benefits and HR outsourcing offering for the same SMB buyer.
• BBSI: Public PEO with a notable construction, light-industrial and trade vertical focus and co-employment model—highly comparable given Acadia's roots serving building-trade sub-contractors and similar worker-classification and workers' comp complexity.
• Stratishr (formerly Sequoia One): National PEO providing co-employment, payroll, benefits and HR technology to growing businesses—closely comparable size, model and SMB focus to Acadia HR.
• Justworks: Venture-backed PEO offering payroll, benefits, HR and compliance via a tech-forward platform to SMBs—comparable co-employment model and customer segment, opposite end of the tech/scale spectrum.
• TriNet: National PEO providing co-employment HR, payroll, benefits and compliance to SMB and mid-market employers; closest publicly traded analog to Acadia's SMB PEO positioning.

Broad incumbents

• ADP TotalSource: PEO division of ADP, the largest U.S. payroll and HR services provider; competes head-on for SMB/mid-market PEO clients while leveraging ADP's broader payroll and HCM portfolio.
• Paychex PEO / HR Outsourcing: Paychex's PEO and HR outsourcing arm bundles payroll, benefits and HR services for SMBs as part of Paychex's broader payroll/HCM stack—an incumbent comparable given Acadia's SMB focus.

Emerging players
