Banks are a great example of this:

"Mastercard, originally known as Interbank/Master Charge, was created by several California banks as a competitor to the BankAmericard issued by Bank of America, which later became the Visa credit card issued by Visa Inc."

SWIFT:

"SWIFT was founded in Brussels in 1973 under the leadership of its inaugural CEO Carl Reuterskiöld (1973–1983) and was supported by 239 banks in fifteen countries"

Several others I can't think of right now.
