Five9 (FIVN) Dollar-Based Net Retention Rate

Measures how revenue from existing customers changes over time after accounting for churn, downgrades, and upsells. For a subscription SaaS provider like Five9, a rate above 100% signals healthy account expansion and predictable recurring growth, while a falling rate warns that churn or weak upsell could undermine long-term revenue momentum.

Retention has declined from earlier highs and settled modestly above 100%, meaning existing customers still expand spend but far less aggressively than before. Management’s commentary shows subscription retention inching up alongside rapid AI ARR growth, so upsells are helping, but AI’s lumpiness and a large on‑premise footprint limit consistent upside. The takeaway for investors: Five9 can drive incremental revenue from its base, yet sustaining materially higher net retention—and the simpler, lower‑risk revenue growth that would bring—hinges on converting more customers to cloud/AI at scale.
