Know why, not how many
Every cancellation returns a reason, in their words.
AI-powered exit interviews for SaaS
WhyLeft asks every customer who cancels why — and turns the answers into the one thing worth fixing next.

A cancelled customer is the most honest person in your funnel. Almost nobody ever asks them.
“Too expensive” is where feedback normally stops. WhyLeft asks what it was too expensive for — and gets the answer that changes your roadmap instead of your price.
It got too expensive for what we were using it for.
That's fair — was there a moment it stopped feeling worth it, or did it build up over time?
Written from what they actually said
When we hit the seat limit, honestly. Going from 3 to 5 people doubled the bill and we only needed one of them in there daily.
Every reply is tagged and read against everything else you have heard. What comes back is not a chart to interpret — it is a recommendation, with the quotes and the MRR behind it.
What to fix first
Integrations are your most expensive gap
9 of your last 24 cancellations mention a missing integration, and Zapier comes up 6 times.
“No Zapier meant it never talked to anything else in our stack.”
“We wanted new signals pushed into Slack automatically.”
It arrives with a reason attached, in their words.
The thing to fix comes ranked by the revenue behind it.
When you fix their reason, they hear it from you.
One price, no feature gates — including the capabilities that ship next year.
When a customer says something worth quoting and lets us publish it, their post appears here — their name, their link. Inventing one would be a strange way to sell a product built on honest answers.
“We run WhyLeft on WhyLeft. When you cancel, you get the exit interview — same email, same follow-up. It would be strange to sell a product I wasn't willing to point at myself.”

I'm Samir. For years I watched the cancellation email arrive, felt bad for a minute, and moved on. When I did write back, people almost always answered — and it was almost never what I'd assumed.
Asking took ten minutes I didn't have, at the moment I least wanted to spend them. So I built the thing that asks.

The email is plain text, sent from your address, signed with your name, with no tracking pixel, no logo, no survey link and no unsubscribe footer beyond the legally required one-click header. It arrives minutes after they cancel, which is exactly when a founder would have written it.
When they reply, the reply goes into a real conversation. Most people never think about it.
More than reply to a survey link — because it isn't one. It's one question from a human address that they can answer by hitting reply, without leaving their inbox or loading a form.
We don't publish a promised reply rate, because yours will depend on your product, your relationship with your customers and how you word the question. You'll see your own rate in the dashboard from your first cancellation.
About five minutes. You connect your billing provider, confirm the name and address your exit emails send from, and write one or two sentences describing what your product does so the AI has context.
There's no code to deploy, no snippet to install, and no data migration. The next customer who cancels gets an interview.
No. Automated AI processing — tagging, follow-up generation, insights, recommendations — receives the reply text and non-identifying metadata only: plan, price, dates, churn tags. Never a name, never an email address.
The one exception is deliberate and founder-controlled: when you personally ask Wylo Copilot a question about a specific customer, it can retrieve that customer's identity — inside your own authenticated workspace only, through the same authorization boundary as your dashboard.
Stripe, Polar, Lemon Squeezy and Paddle are detected automatically — connect the account and cancellations start flowing.
Anything else works through the API, an outbound webhook from your own backend, manual entry, or a CSV import. The billing provider is a convenience, not a requirement.
At most two: the exit interview and one follow-up. That cap is enforced in code, not by policy — the send path checks it before every message.
Win-back emails are a separate, opt-in flow that only goes to customers whose stated reason you've actually addressed.
Your next cancellation is coming.
It can be another number on a chart, or the reason you build the right thing next quarter.
No credit card. Cancel in one click — we'd rather you tell us why.
