Osper, the provider of a prepaid debit card and mobile banking app geared towards the youth market, has closed on $10 million in funding from investors including Index Ventures and Horizons Ventures. The London-based start-up aims to tackle the lack of financial education for the U.K.’s seven million 8-18 year olds by instilling good money habits earlier in life. Its mobile-only, branchless, secure banking service encourages greater financial freedom and responsibility, equipping young people with the money management skills needed for adult life. The service is composed of a MasterCard prepaid debit card and a mobile app, which comes with separate logins for both young people and their parents. Osper will reportedly use proceeds from the funding to launch out of beta and expand the service internationally.
