Sales gets the celebration. Marketing gets the budget. But in most B2B businesses, the largest single revenue lever sits in the 12 months after the deal closes — renewals, expansions, cross-sells, references.
We routinely find clients where a 5-point lift in net retention is worth more than doubling new-logo spend, and costs a fraction to deliver. The work is unglamorous: onboarding redesign, usage telemetry, executive sponsorship rhythms, expansion playbooks.
The companies that win the next decade in B2B will be the ones who treat post-sales as a growth engine, not a service cost. The data is overwhelming, and the runway is open.
