CRED, a two-year-old startup that is helping credit card users in India improve their financial behavior, has raised $80 million in a new financing round, a source familiar with the matter told TechCrunch.

The new financing round, a Series C for CRED, was led by existing investor DST Global. Much of the round — in fact, if not all — has been financed by existing investors, including Sequoia Capital and Ribbit Capital, that are doubling down on Kunal Shah’s startup, the source said on condition of anonymity as they are not authorized to speak to the media.

The new round gives CRED a post-money valuation of about $800 million, the source said. That’s up from about $450 million valuation that CRED attained after its $120 million Series B round last year.

A CRED spokesperson declined to comment.

On CRED, customers are offered a range of features, including the ability to better track their spending across various credit cards, and get reminders. Moreover, CRED incentivizes customers to pay their bill on time by rewarding them points, which they can use to subscribe to a range of premium services and get a discount on purchase of high-quality products.

The platform is not available to all credit card holders in India. The startup requires a customer to have a certain credit score — about 750 — to be able to sign up for the service. This way, CRED has built a customer base that comprises some of the most sought-after people in India.
