Our take

The insurance industry has a payments problem. Because claims processing is customer-facing, there has been heavy investment in improving outgoing payments, while the side of the business that collects premium payments from customers has not benefited from digitisation. What's left is a fragmented chain of manual process and legacy systems, reducing efficiency and introducing a lot of unecessary work. Diesta hopes to improve this situation with a payment processor made for the insurance industry.

The insurance industry is valued at £70 billion, and there is significant competition in this field from startups such as Imburse, as well as older firms like Blink and Computop. However, Diesta's founders have strong experience in the insurance industry and have identified a need for a processor that will integrate easily with a company's existing systems rather than outsourcing or replacing them. Their experience and passion will likely enable Diesta to make significant headway in this market.

Diesta secured seed round funding in 2024, which is being used to develop its software's capabilities and improve its integration with existing insurance systems. It's also investing in talent to make this possible.
