Fiserv is the plumbing behind the payments system — it quietly runs technology for ~10,000 banks and credit unions and ~6M merchant locations, processing ~90B transactions a year. Its revenue splits almost in half: Merchant Solutions (Clover POS + the Carat enterprise platform) and Financial Solutions (core banking, card issuing and money movement like Zelle and bill pay). It bought First Data in 2019 for ~$22B to get Clover and the merchant-acquiring business.
