Powering retention for the next generation of subscription companies
“Sirius integrated seamlessly into our system making the entire process effortless from day one. Within just 4 months, we had optimized and automated 60% of all retention operations. By the one-year mark, that number had climbed past 90%.“
CEO and Founder at Promova
“We run monthly parkings across 25+ San Francisco locations on Sirius and the results speak for themselves. Since moving to Sirius, we cut monthly churn from 12.2% to 2.9%, pushed subscriber retention past 96%.“
CEO and Founder at Parking Nexus
“Since bringing Sirius onto our site, retention stopped being guesswork. Our product team can spot what drives engagement and double down on it. The result is better products and customers who stick around.”

Do your cancel screens look like this?
Static cancel flows leak revenue
Hard-coded pop-ups and generic discounts save a fraction of the customers a real retention engine could.
Margin burns on the wrong offers
Blanket discounts hand money to chronic discount-seekers and abuse-prone accounts who would churn anyway.
AI support agents skip the save
Your AI agents handle cancellations every day with no retention playbook and no personalized offers to deploy.
Turn every cancel click into retained revenue
Sirius closes the leak at every surface your customers cancel through and reports the lift on your own P&L.
Save subscribers at the cancel moment
An in-app widget fires the instant a customer hits cancel and delivers a personalized offer in under 200 milliseconds.
Prove the lift with a continuous holdout
Every save reports against a control group so retained revenue shows up auditable on your P&L.
Protect margin with ICP qualification
Sirius scores every canceller and serves offers only to the customers your finance team wants to keep
Arm your AI agents with offers that convert
Plug Sirius into Sierra, Decagon, Ada, or Intercom Fin so every agent conversation surfaces the right retention move.
