What TandemHR does
Tandem HR is an IRS-certified Professional Employer Organization (PEO) that provides bundled human resource outsourcing services to small and mid-sized businesses across the United States. Founded in 1997/1998 by Chicago-based benefits consultant Bruce Leon, the company operates a co-employment model in which Tandem HR becomes the employer of record for payroll, tax, and benefits purposes while client companies retain control over day-to-day operations. Headquartered in the Chicago area, Tandem HR is recognized as the largest privately held PEO in the Midwest and serves hundreds of thousands of worksite employees nationwide. Since 2024, Tandem HR has operated as part of the Vensure Employer Solutions platform following its acquisition.
Tandem HR's product portfolio is organized around six integrated service modules delivered under a single co-employment relationship: Comprehensive HR Solutions (the umbrella PEO service), Payroll Administration, Human Resources support, Benefits administration, Risk Management (including workers' compensation and safety), and the PeopleHub HR technology platform. PeopleHub is a proprietary 24/7 web portal that gives managers and employees self-service access to employee handbooks, benefits details, payroll information, and time tracking data. The platform-plus-services bundle is positioned as a "best-in-class" HR infrastructure accessible to SMBs at costs typically reserved for larger employers.
Tandem HR generates revenue through recurring per-employee-per-month (PEPM) fees bundled within its PEO co-employment contracts, leveraging pooled buying power across its worksite employee base to offer Fortune 500-level benefits at SMB price points. The company pursues a sales-led go-to-market combining inbound content marketing (HR blog, webinars, social), inside sales via web-form and phone CTAs, and a broker/partner referral channel targeting HR and benefits consultants. The customer base is concentrated in the SMB segment with select mid-market engagements, particularly during M&A-driven growth or benefit transition events. Tandem HR holds IRS CPEO certification, NAPEO membership, and an A+ BBB rating as core credibility assets supporting its white-glove service positioning.
