Product Growth Diagnostic
Product usage is not the same as product growth.
For B2B SaaS teams where users show intent, but activation, team adoption, expansion, or revenue is not following.
The Product Growth Diagnostic is a short, senior engagement to clarify the bottleneck, pressure-test the assumptions behind it, and turn the findings into a practical brief your team can execute from.
At reev, this work rebuilt the pricing architecture, created a behavioral scoring model in PostHog to identify upgrade-ready accounts, and delivered €200K+ ARR uplift in Q1 from existing customers, not new acquisition.
The usage signal is there. The growth system is not.
Many B2B SaaS teams do not need more roadmap ideas. They need to understand why product usage is not turning into activation, team adoption, expansion, or revenue.
Before you rebuild onboarding, change pricing, hire a growth PM, launch Teams, or push PLG harder, diagnose which part of the growth system is actually blocking progress.
- Usage is up, but activation, expansion, or revenue is flat.
- Pricing and packaging do not match how customers experience value.
- Product and GTM teams disagree on what to fix first.
"If users keep showing up but the revenue line does not move, the bottleneck is upstream of the roadmap."
How it works
Week 1 · Understand
Interviews, product walkthrough, funnel review, analytics review, and current strategy/context.
Week 2 · Diagnose
Separate symptoms from root causes. Pressure-test assumptions. Identify the highest-leverage bottlenecks.
Week 3 · Recommend
Prioritized interventions, sequencing, metrics, and a clear brief your team can execute from.
This is usually relevant when:
- Users sign up, explore, or pay individually, but do not expand into teams.
- Activation is unclear or inconsistent.
- Pricing and packaging do not match how customers experience value.
- Team, workspace, invite, or enterprise features are becoming more important.
- Product and GTM teams disagree on what to fix first.
Selected work
Diagnosed a two-tier pricing architecture with no growth ceiling at reev. Redesigned it into a Business and Enterprise model. Delivered €200K+ ARR uplift in Q1 from existing customers.
Built a behavioral scoring model in PostHog using product usage signals to identify upgrade-ready accounts, generating a named account list representing significant expansion ARR.
Delivered reev's first customer-facing AI feature: a natural-language insights engine for fleet operators. Reduced operational overhead by ~30%.
