Side by side
Every difference, including where Sirius leads.
| Tenure | Sirius | Stronger | |
|---|---|---|---|
| Getting started | Tenure:On your own: your site address, a drafted plan. Free during early access. Afterwards: free up to 100 active subscribers, $49 a month up to 1,000, $199 up to 10,000. | Sirius:Book a demo; pricing is discussed on the call. | Tenure |
| When it acts | Tenure:Before the click (going quiet, milestones, trial endings, plan limits), at the click, and after (win-back). | Sirius:At the moment of cancellation, in the customer’s inbox, and through your AI support agents. | Tenure |
| The conversation | Tenure:No chat. Tenure reads what the customer says, then makes one offer at most, with a full-size way out. | Sirius:An AI negotiator in your brand voice, within budget caps. | Different approach |
| Who gets an offer | Tenure:Decided per customer from what they pay, use and say. | Sirius:A real-time fit score decides who is worth a save; the rest pass through to cancel. | Different approach |
| Measurement | Tenure:Saves counted when billing confirms them, money at the paid renewal, the count behind every figure. No holdout yet, so no lift figure. | Sirius:A continuous holdout to prove lift, with A/B-testable thresholds. | Sirius |
| Support agents | Tenure:REST and MCP decisions any support agent can call. | Sirius:Works with Sierra, Decagon, Ada and Intercom Fin out of the box. | Sirius |
| Mobile | Tenure:Packages for iOS, Android, React Native and Flutter that show the hosted flow in your app. | Sirius:A native SDK for iOS, Android, React Native and Flutter. | Different approach |
