Our take

Fintech startups make up the biggest component of the London startup scene, so there can be a lot of noise, but Jaja is making a large splash on the scene with its mobile first credit products and partnership focused strategy.

A large number of credit transactions are still handled using traditional channels, with slow onboarding processes and counter-intuitive tools. Jaja offers mobile-first credit products that focus on fast applications providing a near-instant credit decision.

Jaja has focused its expansion strategy on partnering with established brands. In 2022, a consortium of investors committed to fund up to £120 million in the company. Its new shareholders are bringing valuable insights to the business and will support the company to continue to offer best-in-class core technology, products, and services.
