Mambu's role

Cloud banking platform

ZestMoney is a consumer-centric digital lender founded by Lizzie Chapman, Priya Sharma and Ashish Anantharaman. It is built as a platform that can meaningfully improve the lives of more than 300 million households in the country, who currently have no access to credit cards or any other formal financing options because of insufficient credit history. ZestMoney addresses the gap by giving out small loans, which can grow as the customer repays successfully.

Bringing in a decade of experience in fintech and software development, the founders knew how to create an infrastructure that would allow ZestMoney to adapt their products quickly and repeatedly over time. India's dramatically changing financial market was pressing ZestMoney to ensure a high level of infrastructure responsiveness. A composable architecture would allow the business to react to market changes quickly by launching new products and adapting old ones.

We knew which components were worth building and which were worth buying.

On top of that, due to aggressive timelines linked to fundraising, the team needed a technology partner that was flexible, fast and secure to go to market extremely quickly.

With this in mind, the founders designed ZestMoney's future business architecture and chose Mambu, as it was a perfect match when it comes to philosophies around product design and customer centricity.

Creativity through composable banking.

For both businesses, ZestMoney and Mambu, India was a new market at the time and so the teams collaborated very closely, and launched a new product quickly in a glitch-free implementation.

After a successful business kick off, ZestMoney continued redefining banking products by leveraging Mambu's composable architecture. The team has since invented and launched unprecedented products and services in weeks, and even days. Mambu's cloud platform empowers ZestMoney to plug and play, switch and reassemble products that suit their customers in a better way.

If you can do it in India, you can do it anywhere.

Today, ZestMoney leverages Mambu for loan origination and as its loan management system, servicing 11+ million customers through more than 3000 merchants, including giants such as Amazon, Uber, Flipchart and Decathlon.
