Why Revenue Breaks After Growth - Pricing, CPQ, and Billing Failures with Mark Walker (Nue)

Revenue does not usually fail at the close. It fails quietly after growth has already happened.In this episode of GTM Vault, Rick Koleta sits down with Mark Walker, CEO of Nue, to explain why revenue breaks when pricing models outgrow the systems running them.Most teams assume stalled revenue means a sales problem or an execution gap. In reality, the failure is structural. Pricing uncertainty creeps into late-stage deals. Usage and committed spend models introduce complexity legacy billing cannot absorb. Revenue leakage begins long before dashboards reflect it. When data fragments across pricing, CPQ, billing, and rev rec, AI does not fix the problem - it amplifies it.This episode is for founders and revenue leaders whose pipeline looks healthy but whose margins, velocity, or finance workflows are quietly degrading. The solution is not more pipeline or harder execution. It is coherence across the revenue system.Build systems, not heroics.
