The O'Connor Group

What The O'Connor Group does

The O'Connor Group is a privately held HR outsourcing and professional services firm founded in 2007 by Marcia Zaruba O'Connor, headquartered in King of Prussia, Pennsylvania. The company operates a three-pillar service model: (1) Human Resources Consulting Services delivered on a fractional, interim, or project basis with flexible on-site, virtual, or hybrid engagement; (2) Recruitment-as-a-Service (RaaS), structured as a data-powered talent acquisition solution offered in four tiered packages (Tier 1 sourcing-only, Tier 2 for small businesses up to 50 employees, Tier 3 for mid-sized businesses of 50-500 employees, and Tier 4 for enterprises of 500+ employees); and (3) 57th Street Partners Executive Search, a dedicated division for retained and contingent executive placements concentrated in life sciences and healthcare. Underlying technology is described as a 'data-powered' platform with advanced sourcing and recruitment software, dedicated project managers, weekly or quarterly progress reports with analytics, and tiered access to candidate lists and compensation analysis, though no proprietary AI/ML models are disclosed.

The firm generates revenue through professional services billing on hourly or fixed-fee terms, with engagements scaled from part-time (fractional services starting at 4 hours per week) to all-inclusive support, plus productized offerings such as the 'Essentials of People Management' Leadership Development Program ($2,500 per participant) and paid Executive Summit registration. Go-to-market is consultative and sales-led, with more than 90% of new client relationships originating from referrals; the firm supplements this with thought leadership content (HR After Dark podcast, The Connector newsletter, TOC Services Videos), signature events (annual Executive Summit targeting CEOs), and active regional association membership. The customer base spans Life Sciences, Healthcare, Pharmaceutical, Manufacturing, Professional Services, Information Technology, and Nonprofit sectors, with named enterprise clients including Aclaris Therapeutics, AmeriHealth Caritas, Hamilton Lane, Trinseo, and Blommer Chocolate. A nationwide network of 55+ professionals supports delivery beyond the Pennsylvania headquarters.

Ownership is founder-controlled with no external private equity or venture capital involvement indicated; Meghan Popoleo was promoted to President in 2026 alongside Marcia Zaruba O'Connor as CEO. The firm is WBENC-certified as a Women's Business Enterprise and is recognized on regional and national lists including Inc. 5000, Philadelphia Business Journal Best Places to Work, Soaring 76, and Philly 100. The company is actively operating with no public listing, no disclosed funding rounds, and no parent entity.

Scale indicators3 records

Recent moves7 records

Expansion highlights6 records

Direct peers

• AmplifyHR: Fractional and outsourced HR services firm serving small and mid-sized U.S. companies. Direct peer to TOC's HR Consulting practice in business model, target customer (SMB/mid-market), and fractional HR delivery approach.
• Cielo: Global Recruitment Process Outsourcing (RPO) and talent acquisition partner serving mid-market and enterprise clients. Comparable to TOC's RaaS practice in end-to-end recruiting delivery and analytics-driven approach, but at larger enterprise scale.

Emerging players

• Bambee: Tech-enabled HR outsourcing service providing dedicated HR managers to small businesses. Comparable to TOC's fractional SMB offering and Tier 2 RaaS, though with a stronger software-platform delivery layer.

Broad incumbents

• Insperity: Large-scale PEO providing HR outsourcing, benefits, payroll, and recruiting to SMB and mid-market employers. Comparable to TOC across all three service lines, but at significantly greater scale and as a co-employment PEO rather than a consulting model.
• TriNet: PEO offering HR solutions, benefits, payroll, and recruiting support primarily to SMB clients. Direct overlap with TOC's SMB and Tier 2 RaaS positioning; broader, more standardized, and more capital-intensive delivery.
• Justworks: PEO/HR platform serving SMBs with payroll, benefits, compliance, and HR advisory. Comparable customer segment to TOC's Tier 1–2 SMB base, with a stronger technology-led delivery model.
• Korn Ferry: Global executive search and organizational consulting firm. Directly comparable to TOC's 57th Street Partners Executive Search division in retained C-suite search, with additional RPO and consulting practices.
• Heidrick & Struggles: Global executive search and leadership advisory firm. Closest large-cap public peer to TOC's 57th Street Partners executive search practice, particularly in Life Sciences and Healthcare leadership placements.
• Robert Half: Specialized staffing and talent solutions firm with both temporary placement and direct-hire practices. Comparable to TOC's RaaS and executive search offerings at significantly larger scale and broader geographic footprint.

Others

• Paylocity: Cloud-based HRIS, payroll, and talent management software vendor with a strategic partnership with TOC. Adjacent rather than directly competitive, but its expanding native recruiting features are a competitive threat to TOC's RaaS tiers over time.
