Zelle is the brand name for Early Warning Services, which used to be called clearXchange, and is owned by the biggest banks themselves. When I write there is no middleman or third party, I mean that the money goes from the sender's account to the recipient's account. With PayPal/Venmo/Apple Cash/etc, the money goes from the sender's account, to Paypal/Venmo/Apple/etc's account, and then to the recipient.

Also, with Zelle, you never need to give anyone your bank account number, and you are never authorizing anyone to reach into your account and take money via ACH, like you are with Paypal/Venmo/Apple Cash/etc. It’s also instant.
