The company is a wholly owned subsidiary of Harbour Benefit Holdings, Inc., which also owns Pacific Federal LLC, Associated Administrators LLC, Benefits Administration LLC, and A.W. Rehn and Associates. Zenith serves approximately 300 clients representing over 700 funds and more than 2 million union plan participants across the United States, delivered through a national footprint of 35+ regional offices.

Zenith operates an integrated proprietary technology platform anchored by four role-based "Edge" portals (Participant Edge, Employer Edge, Provider Edge, and Trustee Edge) plus Zenith Flex for consumer-driven reimbursement accounts (FSA/HRA/HSA/HCRA/MRP), with mobile apps on iOS and Android. The platform supports contribution accounting, health claims adjudication, pension/retirement processing, COBRA administration, and financial reporting on a single adjudication backbone, backed by SOC 1 Type II and SOC 2 Type II attestations (August 2024–July 2025 review period). Product solutions overlay the core platform including claims cost containment (with claimed ROI up to 72% on out-of-network claims), J-Code drug rebates, dependent eligibility audits, specialty drug advocacy, MSK navigation, subrogation recoveries, and telemedicine via MD Live and Teladoc integrations.

Revenue is generated through negotiated per-client subscription/managed-services fees structured by plan type (Health & Welfare, Retirement/Pension, or combined) and participant count tiers (Under 250 to 5,000+), under multi-year contracts initiated via a customized RFP process. Go-to-market is sales-led, supported by a dedicated sales team, regional presidents, plan-professional referral networks (consultants, attorneys, auditors), and active participation in industry events (IFEBP, NABTU, IBEW, NLMC). The company reports a 2025 Net Promoter Score of 42 (vs. U.S. industry average of +23) and 87% Client Services Manager satisfaction, supported by an upgraded telephony system that achieved a 4.4/5 customer satisfaction score.
