What is a Managing General Agent (MGA) and how is it different from an insurance broker?

A Managing General Agent (MGA) is an insurance entity that has delegated underwriting authority from one or more carriers — it can bind coverage on the carrier's paper without referring each submission back. Brokers, by contrast, place coverage with carriers but cannot bind without carrier approval. MGAs typically earn 20–35% of premium as a fronting fee; brokers earn 10–20% as commission. MGAs are responsible for their own underwriting, claims handling (or outsourced TPA), and regulatory compliance on the binding authority granted by the carrier.

An MGA is the delegated-authority operator that sits between the broker market and the carrier's balance sheet. Understanding the MGA model is essential for anyone selling AI underwriting tools — the MGA is the single highest-velocity buyer because they own the bind decision.

The legal structure

An MGA holds a written binding authority agreement from one or more carriers. The agreement specifies:

  • Lines of business the MGA may bind (e.g. commercial property under $25M TSI in TX, FL, GA)
  • Underwriting guidelines the MGA must follow
  • Pricing rules the MGA must apply
  • Loss ratio target the MGA is held to
  • Claim-handling authority (some MGAs handle claims; many delegate to a TPA)
  • Audit rights the carrier has over the MGA's book

The carrier remains the legal "insurer" — its name is on the policy, its capital backs the losses, its NAIC filings include the book. The MGA operates the underwriting desk on the carrier's behalf.

MGA vs broker

| | MGA | Broker | |---|---|---| | Can bind coverage | Yes | No (must refer to carrier) | | Holds underwriting authority | Yes | No | | Earns | 20–35% fronting fee | 10–20% commission | | Risks carried | None (carrier's paper) | None | | Regulatory licensing | Producer + MGA license per state | Producer license per state | | Carrier appointments | Few, deep | Many, transactional | | Claims handling | Sometimes (or via TPA) | No |

Why MGAs are the hot ICP for AI underwriting platforms

  • They own the bind decision. Selling AI to a carrier means selling to procurement, IT, actuarial, legal, and the CUO. Selling to an MGA means selling to the founder.
  • Speed is the product. MGAs compete on submission-to-quote time. AI underwriting drops that from 24 hours to 30 seconds — a direct competitive advantage.
  • Loss-ratio incentive alignment. MGAs are held to a loss-ratio target by their carriers. AI tools that move loss ratio 2–5 points directly improve MGA renewals + economics.
  • Smaller IT footprint. MGAs typically have lean engineering teams. They prefer SaaS over building in-house.

The 2025–2026 MGA market

  • 2,000+ MGAs in the US writing across commercial property, specialty liability, cyber, marine, professional lines.
  • Top quartile by GWP: Hippo, At-Bay, Coterie, Cowbell, Vouch, Next Insurance, Pie, Branch (some of these have evolved to full carriers).
  • Lloyd's coverholders (the UK equivalent of MGAs operating on Lloyd's syndicate paper) — ~3,000 globally.

What MGAs need from an AI platform

  • Multi-line support (most MGAs write 2–4 lines)
  • Carrier-specific appetite filters (each carrier the MGA fronts for has its own appetite)
  • Audit trail per carrier (carriers audit MGAs annually; the MGA needs to produce the trail per carrier)
  • Treaty cession tracking (MGAs cede into the front carrier's treaty, not directly)
  • STP rules per carrier-line combination
  • Claims handoff workflow (TPA integration when claims are outsourced)
