How do we model expansion revenue from self-serve users in the first 90 days?
Expansion Math on Self-Serve Base
Capture baseline usage & product-indicated account value (ACV) markers within 30-day onboarding window.
Key Metrics to Track
- Activation Day 0–7: API call velocity, module adoption, team seats invited
- Cohort Day 30–60: Feature depth (nested objects created, workflows triggered, integrations connected)
- Day 90 threshold: Free-tier resource limits hit (seat cap, query rate, storage) = expansion signal
Expansion Conversion Model
Define three buckets based on Pavilion / OpenView research:
- Self-serve only (70%): Low-touch expand at limit hit; email + in-app upsell
- Sales-assist ready (20%): Mid-market signals (5+ seats, cross-functional use); sales-dev touch after Day 45
- Enterprise negotiation (10%): Volume commitments, compliance requirements; full CRM handoff

Track $ACV uplift per cohort day by feature adoption depth. Use SQL window functions to compute rolling 30-day expansion rate. Pavilion reports 18–22% of enterprise SaaS expansion comes from freemium user bases within 6 months of initial signup.

The Bear Case (Customer-Side Adoption Friction)
Three friction vectors:
- Budget reallocation in downturn — services/SaaS get aggressive cuts. 20-30% pipeline compression, 90-day cash buffer.
- Buying-committee expansion — Gartner: 6 → 11 stakeholders/decade. Each adds 30-45 days.
- Procurement-driven price compression — 20-40% discounts are closing condition, not opener.
Mitigation: ACV-expansion tiers, exec-sponsor motions, renewal escalators 5-7% annual.
