Valkyrie vs Churn Buster: failed payment recovery compared
Two different pricing philosophies: Churn Buster charges a flat monthly fee whether it recovers anything or not. Valkyrie only gets paid when your money actually comes back.
What each product is
Valkyrie connects to Stripe, finds failed subscription payments that Stripe's own Smart Retries can't fix (expired, lost, stolen, invalid cards), and emails the customer asking them to update their card. You're billed 25% of what actually comes back, nothing if nothing recovers.
Churn Buster is a broader retention platform covering both dunning (payment recovery) and cancel-flow tooling (the screens a customer sees when they try to cancel), sold as a flat monthly subscription rather than tied to what it recovers.
| Valkyrie | Churn Buster | |
|---|---|---|
| Pricing model | 25% of recovered revenue only | Flat monthly fee, scales with MRR |
| Starting cost | $0 until something's recovered | $269/mo (Dunning Only plan) |
| Full platform cost | Same 25% rate | $430/mo (dunning + cancel flows) |
| Cancel-flow tooling | Not offered | Yes, dedicated product |
| Processors supported | Stripe only | Stripe, Braintree, Recurly, Chargebee, Recharge, and others |
| Setup | Stripe OAuth, ~60 seconds | Account setup + integration configuration |
| Contract | None, cancel any time | Month-to-month, no contract per their pricing page |
The real cost of a flat fee
A flat fee only looks cheaper if you recover far more than the fee every single month. In practice you're paying $269 or more before a single dollar comes back, and that price climbs as your MRR grows whether your recoveries keep pace or not. With Valkyrie there's no such thing as a bad month: if we recover nothing, you pay nothing, and every dollar of our fee is tied to a dollar you got back. We also never bill for payments Stripe's Smart Retries would have recovered on its own, so you only pay for real lift.
The catch with Churn Buster
You pay from day one, regardless of results. The price is pegged to your MRR, so it rises as you grow even when recoveries don't. And getting started means account setup and integration configuration, not a 60-second connect.
