Zelle is not really the same thing as what WePay does. Zelle is peer-to-peer payments, competitive with Paypal, Square Cash, Venmo, etc. (P2P is a term of art in the industry; it's not P2P in the Bittorrent sense. :)

WePay is about providing payments infrastructure to marketplaces and crowdfunding platforms (Lyft, GoFundMe, etc.). WePay are competitive with Stripe's Connect product (disclaimer: my employer). Braintree and Adyen also have similar products.

Congrats to the WePay folks. I hope this new chapter works out well for them!
