Churnstile

The Pitch

Every SaaS company builds two flows with wildly different budgets: the signup, lovingly A/B-tested for years, and the cancellation, written by an intern in 2019 and never opened again. Churnstile is the drop-in fix — a hosted cancellation flow with a tasteful exit survey, tiered save-offers, a pause plan, and an automated win-back sequence. Pricing is a platform fee plus a percentage of “saved revenue,” so we only make money when your customers stay.

Integration is one script tag. Benchmarks across the whole customer network tell you whether your churn is normal for your category. Nobody has this data.

The Delusion

This one is defensible, which is the problem. Churn is universal, the cancellation page is universally neglected, and “we take a cut of the revenue we save” is the kind of aligned-incentive pricing that makes an investor reach for a term sheet mid-sentence. The cross-network benchmark data is a real moat. There is an actual, honest version of this product: one that surfaces a pause plan to someone who just needed a quiet month, and lets everyone else leave with dignity.

We got four slides into the deck before anyone spotted the trapdoor.

The Reality Check

The trapdoor: a percentage of saved revenue means Churnstile earns the most when cancelling is hardest. The drift into dark patterns is not a risk to be managed — it is the pricing model, operating as designed. Every quarterly review becomes a meeting about making one more screen appear between a tired customer and the button they came for.

The legal shortcut is not as neat as the pitch deck claimed. The US Federal Trade Commission’s 2024 Click-to-Cancel rule was vacated before taking effect; in March 2026, the agency opened a new negative-option rulemaking. That uncertainty makes every extra screen a future compliance meeting with analytics attached.

And the recursion is unkind: Churnstile’s own customers will eventually want to cancel Churnstile, at which point our cancellation flow is either a hypocrisy or a live demo of everything they’re escaping.

Why It Stays Unbuilt

Because the good version gets absorbed as a checkbox feature by every billing platform within eighteen months, and the bad version ends with our exit survey being read aloud in a deposition. There is no durable middle. The moat was never the benchmark data; it was a willingness to be the last unpleasant thing a customer experiences on the way out, and that is not a moat anyone should want to defend.

Unwanted Bonus

By the end of the afternoon someone had sketched “retention insurance” — actuarially priced churn protection, underwritten with the benchmark data. It is a genuinely worse idea, and half the room wanted to pivot to it immediately. That was the moment we closed the whiteboard.
