People & revenue continuity — post-close pillars 1 & 2.

The first two post-close integration pillars protect the deal's revenue line. People continuity (the producers who service the book) and revenue continuity (the clients whose business the producers service) together determine whether the modeled economics actually persist post-close. Both pillars run in parallel through the first 100 days; both are engineered, not assumed.

Compensation, communication, sequencing.

Producer attrition runs 25–40% above baseline in the first year post-close at agencies that don't actively engineer retention. Disciplined integration holds that to 5–10% above baseline. The 20–30 percentage-point gap is the buyer's controllable variable.

The five retention-engineering levers:

• Compensation continuity. Producers don't change compensation for at least 12–18 months post-close. Mid-year comp changes are deferred to natural review cycles. Any changes are individually negotiated, not bulk-implemented.
• Role clarity. Producers know who they report to, what's expected, and what changes in the first 30 days. Ambiguity creates attrition. Written role definitions distributed within the first week.
• Communication discipline. Direct communication from the buyer's leadership to producers in week 1. Structured check-ins through week 13. Transition-team availability for issue resolution. Producers who feel unheard leave.
• Integration sequencing. Technology migrations, comp-grid changes, reporting-structure changes are sequenced — not bunched. Producers absorb one change at a time; multiple simultaneous changes drive attrition.
• Retention bonuses. For top producers, explicit 12–18 month retention bonuses with vesting that aligns producer interest with buyer interest. Not for everyone — surgical use.

Communication, carriers, AMS, renewals.

Attrition in the first 90 days runs 2–3× the steady-state attrition rate. The work is to compress that spike — through deliberate client communication, carrier-relationship preservation, AMS continuity, and renewal-cycle protection.

Four workstreams structure the client-continuity work.

Renewal-cycle protection is the fourth client-continuity workstream. The post-close renewal calendar determines workload spikes and client-facing-friction risk. Renewal calendars clustered in the first 60–90 days post-close need explicit capacity planning; renewal calendars later in the integration window have more room for normal-cadence handling.

Both pillars run in parallel.

The two pillars run in parallel because they're operationally interdependent. Producers service clients; producer-retention success enables client-retention success. Client-relationship preservation requires producer continuity; producer retention is supported by client-relationship work that gives producers stable accounts to manage.

Failed coordination produces predictable patterns. Producers leaving in week 4 means top-account orphaning; orphaned accounts attrit at 40–60% rates instead of 5–10%. Client attrition signals declining commission income; producer earnings drop; producer-retention pressure compounds. The negative spiral can dismantle a year of pro-forma in 90 days.

The integration-team structure matters. A dedicated post-close integration team that owns both pillars produces coordinated execution; pillar-by-pillar handoffs between functional teams (HR for producers, sales for clients) produces gaps.

People and revenue continuity are pillars 1 and 2 of seven. The risk-and-capital cluster covers pillars 3 and 4 (E&O coverage continuity, working-capital and capital-stack management). The operational-asset-continuity cluster covers pillars 5, 6, and 7 (technology, brand, governance). The Pillar — Seven Operational Pillars for Buyers — covers the full framework.
