The Australia and New Zealand business arm of data services provider Experian has acquired Australian fintech Look Who's Charging to boost the appeal of its open banking platforms and services to local financial institutions.Experian has claimed its open data system "facilitates 40 per cent of all UK open banking application program interface requests", and the Look Who's Charging deal "will create a market leading open data platform in the Australian market that will have wide ranging benefits for consumers, businesses and financial institutions". Look Who's Charging, which allows customers to identify merchants behind "unrecognised" bank transactions, is already integrated with a number of Australian banks - including the majors - with data directly available to millions of Australians via their existing digital banking applications.Experian is therefore counting on its own track record in the UK, combined with the Look Who's Charging acquisition, to give it added clout when it pitches its platform and related services to Australian banks.Andrew Black, managing director of Experian Australia/NZ said the platform "will help our customers lend more responsibly while enhancing their fraud checks and reducing their call centre traffic for unrecognised transaction queries, as well as ensuring consumers have a greater understanding of their financial situation."Stuart Grover, a co-founder of Look Who's Charging, said Experian's scale gave his firm the opportunity to reach more Australian consumers and financial institutions, before it is "also rolled out to other key markets around the world".The move is Experian's sixth investment in Asia Pacific since 2017, following its venture capital style investments in Asian fintechs: Grab, a financial services app for unbanked communities; Jirnexu, a customer acquisition and management service; credit risk assessment and related services provider C88 Financial Technologies; Indian retail finance and investment site BankBazaar.com; and the financial management platform CompareAsiaGroup.
