The financial tech firm Plaid announced this week that it’s doubling its workforce in Europe. That is largely because its planned $5.3 billion merger with Visa fell apart earlier this month, after the Department of Justice filed an antitrust lawsuit. Plaid is a platform that lets you, a customer, link your bank account to a fintech app like Venmo or Robinhood. You log in using Plaid’s interface, but the bank itself is cut out of the loop. The banks hate that. Visa could have used Plaid to expand beyond payments and maybe be legitimized in the eyes of banks.
