Company background: CoAdvantage.
CoAdvantage was founded in 1997 and grew as a Florida-based PEO with a Southeast core, serving roughly 110,000 worksite employees. In June 2025 it merged with PrimePay, the payroll and HCM provider, under Aquiline Capital. The combined company brings CoAdvantage's PEO operation together with PrimePay's HCM technology.
The platform story is the point of the merger. CoAdQuantum, CoAdvantage's proprietary system, is now paired with PrimePay's HCM stack, which should mean a stronger technology offer than a regional PEO usually fields. Should is the operative word in 2026: integrations take time, and the roadmap an employer is sold today may not be the one delivered next year.
CoAdvantage holds IRS CPEO certification and ESAC accreditation, which puts it in the compliance-sensitive bracket alongside the national PEOs. That is worth noting for a regional PEO; many of its size carry one or neither.
