Gravy, a startup helping subscription-based businesses recover failed payments, has raised $4.5 million in Series A funding for its specialized combination of technology and a human workspace that works to reacquire customers lost to what’s known as “involuntary churn.” That means the customer didn’t choose to end their subscription, but — for any one of hundreds of possible reasons — their credit card payment failed.

Typically, subscription-powered businesses attempt to correct this issue with technology — like sending automated emails, for example. Gravy, however, has developed a different solution that pairs its U.S.-based retention specialists with technology that alerts them to the failed payments. It then sells this whole system as a package to clients who use Gravy as an extension of their own workforce.
