What is Stay AI?
Stay AI is a Shopify subscription retention platform that uses AI to predict churn, offer personalized save offers, and optimize subscription experiences. It focuses on keeping subscribers from cancelling. Pricing starts at $499/month + revenue share. It targets DTC brands with established subscription programs.
Where Stay AI Falls Short
Subscription Retention, Not Per-Order Revenue Growth
Stay AI prevents subscribers from cancelling. It does not build the bundle offers that grow what those retained subscribers spend per order.
No Bundle Builder or Tiered Cart Rewards
Stay AI manages churn prediction, save offers, and retention flows. It does not create tiered bundles, mix-and-match shopping experiences, or combined reward stacks.
Premium + Revenue Share Pricing
Stay AI costs $499/month plus a revenue share. Tiergain starts free. For brands that need AOV growth before retention investment, Tiergain delivers ROI at a fraction of the cost.
Retaining Low-AOV Subscribers Is Less Valuable Than Growing Their AOV
Stay AI retains a subscriber ordering $34/month. Tiergain lifts that order to $89/month. Retaining the $89 subscriber is 2.6x more valuable than retaining the $34 subscriber.

Bundle subscribers are harder to churn than single-product subscribers
