- Switching cost: Retraining models, re-integrating tools
- Vertical moats: Compliance playbooks hard to replicate
- Usage growth: AI handles more interactions over time (NRR >100%)
Net Revenue Retention (NRR)
Cohort-based NRR (Month 12):- Top Quartile Voice AI: 130-160%
- Median Voice AI: 105-120%
- Bottom Quartile: 85-100%
- Expansion triggers:
- Add new use cases (start with order status → add payment IVR)
- Geographic rollout (start US → expand India, LatAm)
- Increase automation % (20% → 40% of calls)
- Pricing levers:
- Volume tiers (unlock discounts at 5M min/month)
- Success fees (% of agent hours saved)

Profitability Milestones
Path to EBITDA Positive (Typical Timeline)
India Difference:
Indian companies reach EBITDA-positive earlier:
- Exotel: EBITDA+ in H2 FY24 at $54M revenue
- Route Mobile: Profitable at ₹4,023 Cr ($484M)
Rule of 40
Definition: Growth Rate (%) + EBITDA Margin (%) ≥ 40%

- Scale ($30-100M ARR): Balance (40-60% growth, EBITDA -10% to +5%)
- Mature (>$100M ARR): Efficiency (20-30% growth, EBITDA +15-25%)
