Churn Intervener
AI agent that monitors customer health daily across PostHog, support, NPS, and billing via MCP, diagnoses root cause, and delivers a tailored intervention package to CS.
The problem
Churn was always discovered too late — at renewal time, when the customer had already decided to leave. The signals existed weeks or months earlier: usage declining, support tickets going unresolved, NPS dropping, billing issues appearing. But this data lived in four separate tools (PostHog, the support system, NPS surveys, billing) that nobody was monitoring in aggregate. Customer Success discovered losses after the fact, with no time to intervene.
Our approach
A churn detection agent connected to PostHog (usage patterns), the support system (ticket volume and resolution), NPS surveys (sentiment), and billing (payment issues) via MCP. When multiple signals converge for a customer, it doesn't just alert — it diagnoses the root cause, identifies what specifically changed, and drafts a personalized intervention package: the right combination of technical fix, account credit, and relationship outreach for that specific customer's situation. Customer Success receives a one-click action plan in Slack.
How it works
- Daily checks customer health signals across PostHog, support, NPS, and billing via MCP.
- Maintains a rolling health score per customer combining usage, support, sentiment, and billing trends.
- Triggers a deep diagnosis when multiple signals converge above threshold (e.g. usage down 30%+ AND tickets up AND NPS dropped).
- Cross-references support tickets and recent product releases to find specific root causes.
- Assembles a tailored intervention package: technical fix with ETA, appropriate credit amount, personalized outreach for the CS lead.
- Delivers a Slack card to CS with one-click execution options.

Frequently asked questions
How can SaaS companies detect and prevent customer churn before renewal?
SaaS companies can detect and prevent customer churn before renewal by monitoring usage, support, NPS, and billing signals daily via an AI agent — identifying at-risk accounts 3+ weeks before renewal when intervention is still possible.
What customer data signals indicate churn risk?
Churn risk signals include daily active usage declining 30%+ versus the 30-day average, unresolved support tickets accumulating, NPS scores declining by 3+ points, and payment method issues — especially when multiple signals appear simultaneously.
How do you personalize customer retention outreach with AI?
Personalize customer retention outreach with AI by having an agent diagnose the specific root cause for each at-risk account — whether it's a product bug, a feature gap, or a relationship issue — and generate a targeted intervention matching the customer's actual situation.
Can AI automatically detect and prevent customer churn?
Yes — an AI churn detection agent can monitor customer health signals daily across PostHog, support systems, NPS, and billing via MCP, identify at-risk accounts automatically, diagnose the root cause, and deliver a personalized intervention plan to the CS team within hours of the risk being flagged.
What is the success rate of AI-driven churn intervention?
AI-driven churn intervention achieves a 60%+ success rate on at-risk accounts when the agent identifies the root cause accurately and delivers the intervention at least 3 weeks before renewal, compared to near-zero success when churn is discovered at the renewal cancellation.
