• The Segal Group: The Segal Group is one of the largest independent actuarial and benefits consulting firms serving multiemployer (Taft-Hartley) plans, with deep specialism in retirement and health & welfare consulting — Horizon's closest direct competitor in the multiemployer niche.

Broad incumbents

• Mercer: Mercer is a global consulting firm with a large actuarial and benefits practice serving single-employer and multiemployer plans; Horizon's co-founders previously worked at Watson Wyatt (now part of WTW/merged with Mercer in some areas), and Mercer competes for the same multiemployer RFPs from a much broader platform.

• Aon: Aon is a global professional services firm with a sizable actuarial and retirement consulting practice (including a health practice Horizon's Justin Muir previously led at Aon); competes with Horizon in the multiemployer retirement and health & welfare space from a much larger resource base.
• Buck Global (now Buck): Buck is an integrated HR and benefits consulting firm with a long-standing actuarial practice serving multiemployer plans; Mary Ann Dunleavy at Horizon began her career at Buck Consultants, indicating strong cultural overlap and competitive positioning.

Others

• Groom Law Group: Groom Law Group is a Washington, DC-based law firm specializing in multiemployer benefit plan regulation and compliance; not a direct competitor but a frequent collaborator and thought leader in the same multiemployer ecosystem Horizon serves.

Emerging players
