Case Study · AI Productivity Assistant
Flat seat pricing left heavy users underpriced. A controlled usage-based test, then a structure the billing system could actually ship.
Published July 28, 2026
Problem
An AI productivity assistant on flat per-seat pricing. Heavy users were massively underpriced, and the flat fee was the number customers noticed and resisted.
Method
Designed a controlled usage-based experiment on a small cohort, with a comms split to isolate the reaction to the change.
Solution
Usage tiers layered onto seats. Org-level billing chosen over user-level at a fraction of the build effort.
Impact
15% more revenue in the test cohort. Conversion tripled relative to baseline — roughly 10% to a third of the cohort. Mix shifted toward annual plans.
