DriftWatch analyzes behavioral patterns with Hidden Markov Models and scores every user's churn risk in real time. One API call. No ML expertise required.
Launching September 1st · First 20 customers get 40% off for life
DriftWatch sits between your product and your retention workflows. Push events in, get churn scores out.
Send logins, feature usage, billing events, and cancellations via our REST API or Stripe webhook. Any event type is accepted.
Each score includes churn probability, risk tier, the top behavioral signals driving the score, and a specific recommended action.
Receive a Slack alert the moment a user crosses into high risk. Query all your at-risk users to feed your CRM or trigger email sequences.
Everything you need to integrate churn prediction into your stack without standing up an ML pipeline.
A Gaussian Hidden Markov Model learns the behavioral patterns specific to your product — not generic rules or thresholds.
Score a single user in under 50ms or batch-score up to 500 at once. Both endpoints are tenant-scoped and authenticated.
Get notified the moment a user crosses into high risk. Alerts fire on the transition only — re-scoring the same user never spams your channel.
The model retrains automatically on your data every night. The more events you push in, the sharper the predictions become.
Connect your Stripe account once and billing events — failed payments, cancellations, plan changes — flow in automatically.
Every score includes the top behavioral signals and a specific recommended action, so your team knows exactly what to do next.
One endpoint to push events. One to get a score. The response tells you not just the probability but exactly what to do about it.
Most churn tools are dashboards you log into. DriftWatch is an API you call — and it tells you exactly what to do next, not just what happened.
| DriftWatch | Most churn tools | |
|---|---|---|
| Integration | REST API — plug into any stack in an afternoon | A platform you log into separately from your workflow |
| Scoring model | Gaussian HMM trained nightly on your users' data | Generic activity thresholds or rules the same for all customers |
| Output per score | Probability + risk tier + top signals + recommended action | A score or health number — interpretation left to you |
| Alerts | Slack alert fires once on transition into high risk — no noise | Periodic digest emails, or manual dashboard checks |
