Brokerage acquirers stop revenue leakage by having an account-level joint go-to-market plan finished before close, not started after it. McKinsey found the average merging company loses 2 to 5% of its combined customers. In brokerage, revenue sits with producers. A plan built in a clean team gives every account an owner and a next step on Day 1.
Brokerage deal flow in 2026 is large, small and constant
Private capital-backed buyers accounted for more than 70% of announced US brokerage transactions in the first half of 2026, according to MarshBerry. (MarshBerry) The deals run from $17 billion down to regional agencies whose prices are not disclosed.
| Deal | Announced | Size | Detail |
|---|---|---|---|
| Aon acquires USI from KKR | Aug 31, 2026 | $17.0 billion | USI is the 10th-largest US broker, about $3 billion in revenue. Close expected Q4 2026. (Aon) |
| Sequence Holdings and DFO Management take Baldwin private | Sep 14, 2026 | $7.7 billion | Close expected Q1 2027. (Business Wire) |
| Gallagher completes AssuredPartners | Aug 2025 | $13.45 billion | (Insurance Journal) |
| Brown & Brown acquires Accession (Risk Strategies, One80) | Jun 2025 | $9.8 billion | (Insurance Journal) |
| NFP, an Aon company, acquires Moores Insurance Management | Sep 14, 2026 | Not disclosed | Minneapolis. (Aon) |
| EPIC acquires Korotkin Insurance Group | Sep 17, 2026 | Not disclosed | Michigan. (Insurance Journal) |
| World Insurance acquires TE Freuler | Sep 16, 2026 | Not disclosed | Somerset, NJ. (Insurance Journal) |
| Equal Parts acquires ProSource | Sep 18, 2026 | Not disclosed | Plano, TX trucking specialist. (Insurance Journal) |
| Gallagher's RPS acquires Med James | Jul 10, 2026 | Not disclosed | Six-state MGA and wholesaler, days after RPS bought Wilson M. Beck. (Insurance Business) |
Two things stand out. USI itself made more than 90 acquisitions under KKR ownership. (PLANADVISER) And two weeks after signing USI, Aon's NFP announced another acquisition. Large brokers integrate continuously, often several deals at once.
Where revenue leaks in a brokerage acquisition
A brokerage buys books of business held by people. The leakage shows up in 3 places.
- Clients leave. The average merging company loses 2 to 5% of its combined customers, based on McKinsey's analysis of 124 mergers. (McKinsey)
- Acquired books do not fully renew. Insurance Journal's guide to agency acquisition math uses 85% retention as the common assumption and 90% for strong performers. (Insurance Journal)
- Cross-sell never arrives. Almost 70% of mergers in McKinsey's database failed to achieve their expected revenue synergies. (McKinsey) In a separate survey of 200 M&A executives, the average gap between revenue synergy goal and result was 23%, and revenue synergies took about 5 years to realize against about 2 for cost synergies. (McKinsey)
Apply McKinsey's 2 to 5% band to a broker the size of USI and the exposure is $60 million to $150 million of annual revenue. That is benchmark arithmetic on public figures, not a forecast for any deal.
Why planning on Day 1 is already late
Until close, the buyer and the target must operate as independent businesses. The FTC states that "right up until consummation, the merger parties are still independent businesses and they must continue to operate independently," and that pre-merger information sharing can contribute to unlawful gun jumping under the HSR Act. (FTC) Aon and USI will continue to operate independently until closing. (Coverager)
Without a clean team, commercial planning cannot start until close. That puts planning in the same months that clients and producers decide whether to stay.
The legal route to an earlier start is a clean team. The FTC's guidance is that clean teams should exclude anyone responsible for competitive planning, pricing or strategy, and that reports leaving the clean team should contain only blinded, aggregated data. EY-Parthenon reported a clean room engagement in which synergy initiatives were identified 6 months ahead of the standard timeline. (EY) BCG puts a number on time: accelerating $600 million of run-rate synergies by 1 month is worth $50 million of profit. (BCG)
What a Day 1 joint go-to-market plan contains
A Day 1 plan is not a slide on synergy targets. It is a working plan at account level:
- A combined revenue map by client, line of coverage and product, across both firms.
- An overlap census. Shared clients, conflicted accounts and producers competing for the same relationship.
- A key-person register. Which revenue depends on which producer or account executive.
- Stakeholder maps for every account on both sides.
- White space per account. Cross-sell and upsell by line, product and segment.
- Coverage design. One owner per account, with conflicts routed to a human decision.
- A retention priority list ranked by revenue held and key-person concentration.
- The first 100 days by account, with Day 1 contact sequencing.
With that plan in hand, producers sell the combined book on Day 1 instead of spending the first months of the integration mapping it.
How MAIQ builds the plan before close
MergerAcquisitionIQ (MAIQ) is SAIQ's M&A deal intelligence engine. It runs two engines against one deal thesis:
- Organizational intelligence reads the target's organization from public workforce evidence and SAIQ's workforce perception dataset. It needs no access to the target, so it can run at screening. It produces category scores against peers and a register of integration barriers.
- Commercial intelligence reads read-only extracts from both firms inside a clean room and produces the combined revenue map, overlap, white space, stakeholder maps, coverage design and first 100 days.
Delivery runs in stages: diligence, pre-close planning, then post-close integration. A program takes 6 to 12 weeks depending on deal size and complexity, and stage 1 needs to begin 8 to 12 weeks before close for the plan to be complete on Day 1. At close, MAIQ converts to SAIQ, so the plan becomes the system producers work in rather than a report that ages.
No CRM integration, no CRM change
MAIQ does not require either firm to change or integrate its CRM or agency management system. It works from read-only extracts, with no schema change, no migration and no cutover, across any CRM or several on either side. Systems consolidation stays off the critical path. If the combined firm consolidates systems later, the mapped book carries across.
For a roll-up running several agency management systems from past deals, this is the difference between selling now and selling after the systems project.
How MAIQ reduces diligence and integration consulting fees
Integration spending is rising. PwC found that 59% of companies spent 6% or more of deal value on integration in 2022, up from 38% previously. (PwC)
Much of that spend is manual analysis billed by the hour: customer overlap, account white space, coverage design and organizational assessment. It is also sampled. BCG states that its clean teams "may look at the top 100 customers of the target company," but "won't look at all 500 customers." (BCG)
MAIQ replaces that manual analysis with a fixed program fee, quoted by tier before stage 1 begins, and reads the full client base rather than a sample. Program governance, legal counsel and senior judgment stay where they are. The fee stops tracking the length of the process, and the output stays in use after close instead of leaving with the advisory team.
How the options compare
| Approach | Strength | Limit | Plan ready at close | Stays after close |
|---|---|---|---|---|
| Strategy firm or Big 4 integration office | Governance, cadence, senior judgment | Manual, segment-level analysis billed by the hour | Partial | No |
| Advisory clean team | Compliant pre-close synergy analysis | Sample-based by design; aggregated report | Aggregated only | No |
| Human capital diligence advisers | Leadership and retention judgment | Needs management access, so it starts late | Organization only | No |
| CRM consolidation first | One system of record long term | Commercial plan waits for the systems project | No | Yes, after migration |
| MAIQ | Per-account plan and barrier register built pre-close, no CRM change | Does not replace governance, counsel or senior judgment; needs to start 8 to 12 weeks before close | Yes | Yes, converts to SAIQ |
Why speed matters most in PE-backed roll-ups
A roll-up's return depends on growing the combined book inside a fixed hold period. Each acquisition restarts the same clock: clients and producers decide in the months after close, and a plan that arrives later misses them.
Serial acquisition also multiplies the problem. A platform that closes a deal a month is always integrating. If every integration waits for a systems project and a consulting engagement, the backlog grows with the deal count. A repeatable Day 1 plan, built the same way on every deal, is what lets integration keep pace with acquisition.
Proof from brokerage
SAIQ has been deployed for close to a year at one of the 3 largest global insurance brokerages, a multi-CRM, multi-line business. Four of the top five global brokers run SAIQ.
Frequently asked questions
What is revenue leakage in an insurance brokerage acquisition?
Revenue leakage is revenue lost between signing and full integration: clients who move, acquired books that do not renew, and cross-sell that never happens. McKinsey puts typical customer loss in mergers at 2 to 5% of the combined base.
Can brokerage acquirers plan go-to-market before close without gun jumping?
Yes, inside a clean team structured with counsel. The FTC's guidance is that clean teams exclude anyone responsible for competitive planning, pricing or strategy, and that only blinded, aggregated output leaves the team. MAIQ runs inside that structure.
How long does MAIQ take?
A MAIQ program takes 6 to 12 weeks depending on deal size and complexity. Stage 1 should begin 8 to 12 weeks before close for the plan to be complete on Day 1.
Does MAIQ require changing or integrating CRMs?
No. MAIQ works from read-only extracts of each firm's existing systems, with no migration or cutover. After close it converts to SAIQ, which is CRM-agnostic and connects to any CRM through MCP.
How does MAIQ reduce due diligence and consulting fees?
MAIQ replaces manual customer overlap, white space, coverage design and organizational assessment work with a fixed program fee quoted before work begins. Governance, counsel and senior judgment remain with the deal team and its advisers.
Sell the combined book on Day 1
Every brokerage deal is priced on the combined book growing. The acquirers who capture that growth are the ones whose producers know, on Day 1, which clients they own, who else is calling them and what to sell next.
