Most churn isn't a goodbye. It's a failed payment.
REX follows up every failed payment: an email, a text, then a friendly call in your customer's own language, within rules you set. It starts in shadow mode, so you see every decision first.
Revenue leaks in the gaps between tools.
One failed payment. A silent downgrade. A renewal that slipped past Tuesday. Your team sees the report on Friday. REX sees the first twitch.
It connects the dots, calls the customer in their own language, and puts a specific next move in front of you. The job is not to make noise. The job is to bring the money back before it becomes a forecast footnote.
REX reads payment, product, and support activity as one live customer picture.
It traces the drop to a real cause, not a generic risk score.
Every rescue ends with an action taken and a receipt in the ledger.
Before you join.
What is REX?
REX is Softknock's revenue execution agent. When a subscription payment fails, REX follows up for you: an email, then a text, then a friendly phone call in your customer's own language, within rules you set. It can send a payment link, agree a new date, or offer a pause, and it checks that the payment went through.
What is involuntary churn?
It's losing a customer who never decided to leave: their card expired, hit a limit, or their bank declined the charge, and nobody followed up. Recurly's benchmarks put it at 20–40% of all subscription churn, and it's the easiest churn to win back.
Doesn't Stripe already retry failed payments?
Stripe retries the card and sends an email. REX adds the personal follow-up that retries can't: a conversation, a new date agreed, a payment link sent while the customer is on the phone, and a check the next day that they paid.
Will REX annoy my customers?
REX starts quietly, with an email and then a text, and only calls if the payment is still unpaid. It keeps to your calling hours, rests between contacts, and anyone who asks not to be called is never called again.
Can I see what REX would do before it contacts anyone?
Yes. Every account starts in shadow mode: REX works through your real failed payments and records who it would contact, when and what it would offer, without contacting or charging anyone. You switch it on when you'd have made the same calls.
Which languages does REX speak on calls?
About 17, including English, Hindi, Tamil, Telugu, Bengali, Spanish, French and Portuguese. REX answers in the language the customer speaks.
Which billing systems does REX work with?
Stripe today. Razorpay and Cashfree are next, for UPI Autopay and e-mandates in India.
