This issue has led to the emergence of aggregators that do the work of connecting to bank APIs, which they then provide as a standardized suite to their customers. 

TrueLayer is one of these aggregators. It’s worked with a slew of fintechs, including alt lender Zopa and personal finance management (PFM) chatbot Plum, helping them to connect to banks in the UK by streamlining the integration process. Business Insider Intelligence recently spoke with Shefali Roy, COO of TrueLayer, and Elise Nunn, head of operations at Plum, about their partnership, as well as open banking’s growing pains and the role it’s poised to play in the future.
