THE PLAYBOOK — Portfolio, Not the Pipeline

Broker – MGA Compounding Growth Opportunity: the largest unclaimed pool of specialty premium is already written — it sits inside broker books that cannot be fixed and cannot be released

Every large retail broker carries a book it would rather not discuss: small-commercial E&S — thousands of policies, average premium in the low thousands, serviced by handlers whose time is priced against programmes a hundred times larger. On a representative book — 15,000 policies, $108m GWP — commission at 12% earns $12.96m; cost to serve at $1,050 a policy consumes $15.75m. The book loses $186 on every policy — yet it cannot be released without endangering the anchor relationship. That is precisely why it is an opportunity rather than a problem. MGAs have spent a decade renting growth one submission at a time while this portfolio sits already written, already renewing, with a counterparty who has a financial reason to move.

The Four Rungs — Four Businesses, Not Four Price Points

A unified ladder across book transfer and consolidation — each rung is a different business with its own economics, risk and liability
2 / 3 · THE MODEL
1

Service only / Migration factory

Fee income under the broker's brand. Fastest to stand up, lowest resistance — a contract, not an asset.
2

Service + place / Migrate & run the queue

Bind on own paper where appetite fits; fee discounted against commission. Alignment that shows up in the numbers — the natural entry point.
3

Full transfer / Own the back office

Broker of record moves; renewal economics in perpetuity. The only rung that creates enterprise value.
4

Hybrid by segment

Where most arrangements land — and the most commonly mispriced. A third operating model, not a midpoint.
⚠ THE JUMP — between Rung 2 and Rung 3 the duty of care moves in one step: price it, insure it, be the supplier not the defendant

Three hard truths

1 · The deciding number is the share you would genuinely underwrite — measured on the broker's in-force book as a distribution, never an average. Below break-even, service it; above it, owning the renewals beats five years of servicing profit.
2 · Rung 3 always earns less than Rung 2 in year one. Licences, onshore advisory, PI cover and client consent are paid up front while renewal income builds. You do Rung 3 because you end up owning the business.
3 · Liability does not creep — it jumps. The moment you become the client's broker you stand in the advice chain. Charge for the jump and buy cover for it.

Very few MGAs are equipped to take a book — not because the underwriting is difficult, but because taking a book is a servicing, licensing and liability act. The deal is won on four dimensions: capability, genuine underwriting share, duty of care, and broker economics. Price is the last of the four, not the first.

The Move — and What It Is Worth

Blueprint all four rungs · enter at Rung 2 · escalate to Rung 3 · let intelligence compound every acquired book
3 / 3 · THE VALUE

The move

Blueprint all four.
Design every rung before you enter one — the segmentation gate (underwrite / new vehicle / Lloyd's–London · migrate / absorb / retire) is close to non-retrofittable later.
Enter at Rung 2.
Supply the capacity the broker cannot free up — service + place, fee discounted against commission. Best year-one economics of any rung.
Escalate to Rung 3.
Contractually pre-agreed, priced for the liability jump. Renewal economics in perpetuity — the only rung that creates enterprise value.
Layer intelligence on top.
Broker IQ reads every acquired book from day one — every point of cross-sell lift compounds across every book the group buys next.

The value — modelled on one representative book

Broker's pain removed
+$2.79m / yr
MGA premium acquired
$76–86m GWP
Cross-sell compounding
+20–30% / book
Enterprise value
Renewals in perpetuity

Ten weeks of diagnostic on one real book replaces a year of conviction. The brokers cannot fix these books and cannot let them go; the consolidators cannot absorb what they keep buying. One bridge serves both — and the counterparty on each side already has a financial reason to move. That is the entire opportunity — and it will not stay unclaimed for long.

THE VALUE: the broker converts a $2.79m annual loss into a clean exit with the client relationship intact; the MGA converts servicing fees into an owned, renewing portfolio with +20–30% cross-sell compounding on every book thereafter — growth owned, not rented.
