Our take
With more of people's lives spent online, finding ways to make online payments and identity verification easier, more secure and private has become increasingly important. This is what Yaspa is setting out to do.
Yaspa uses Open Banking to facilitate instant and secure bank payments that are more cost-effective than traditional cards. It also aids regulated gambling operators in verifying the financial health and identity of their customers. Yaspa operates in the UK and Europe across trading, charities, eCommerce and iGaming markets, among others. It's authorised by the UK Financial Conduct Authority, with clients including Wonderful, Metro, and Capital.com, with Novibet as a partner.
As well as being backed by leading investors (e.g Metavallon VC, SGH Capital, and Fin VC), the company's founder - James Neville- is extremely experienced in this space as ex-CTO of Worldpay. Yaspa has also won prestigious awards, such as the SiGMA Europe B2C Award and was named 2025's Best Payment Facility at the Card & Payment Awards, indicating its strength within the payments space.
