Grow Credit, which builds credit scores by paying for online subscriptions, gets Mucker cash

Grow Credit, the startup that launched last year to help customers build out their credit scores by providing a credit line for online subscriptions like Spotify and Netflix, has added Mucker Labs as an investor and closed its seed round with $2 million in total commitments.

The Los Angeles startup founded by serial entrepreneur Joe Bayen, had been bootstrapped initially and then received funding from a clutch of core angel investors before signing a deal with Mucker earlier this month, according to Bayen.

Using the Marqeta platform, Grow Credit can extend a loan to customers to expand their subscription services. Using the Mastercard network for payments, and Marqeta's tools to restrict payment access, Grow offers credit facilities to its customers to pay for their monthly subscriptions. By using Grow Credit for those payments, users can improve their credit scores by as much as 61 points in a nine-month span, says Bayen.

The company doesn't charge any fees for its loans, but users can upgrade their service. The initial tier is free for access to $15 of credit, once a user connects their bank account. For a $4.99 monthly fee, customers can get up to $50 of subscriptions covered by the service. For $9.99 that credit line increases to $150, Bayen said.

Increases to a user's credit score can make a significant dent in their costs for things like lease agreements for cars, mortgages for houses and better rates on other credit cards, said Bayen.

Everything is cheaper, you can get access to a credit card with lower interest rates and better rewards," he said. We're looking at ourselves as the single best route to getting access to an Apple card."

Additional capital for the new round came from individual investors like DraftKings chief executive, Jason Robins; former National Football League player and hall of famer Ronnie Lott; and Sebastien Deguy, VP of 3D at Adobe.

Coming up, Grow Credit said it has a deal in the works with one very large consumer bank in the U.S. and will be launching the Android version of its app in a few weeks.
