PayPal and eBay (2002)
PayPal had a usable way to move money online but no distribution. eBay provided it, making PayPal the default payment method on auctions. eBay bought PayPal for $1.5 billion in stock in October 2002.
PayPal became the standard for consumer internet payments and later a company worth hundreds of billions at its peak.
The playbook stuck: a new payment rail succeeds when an anchor platform routes volume through it.
Velocity needs the same anchor. Visa's investment and pilot are the analog of eBay's channel.
