PayPal and the email that had to be answered
In the autumn of 1998, Max Levchin walked into a finance lecture at Stanford and found himself one of six people in the room. The speaker was Peter Thiel. After the talk, the two men spent four hours at breakfast talking about cryptography and money. By December they had incorporated Confinity in a borrowed Palo Alto office and begun writing software for a device that would change nothing: the Palm Pilot.
The original idea was a digital wallet for handheld computers — point your Palm at a colleague’s, tap a button, and beam them dollars across the table via infrared. It worked, technically. But almost nobody owned a Palm Pilot, and almost none of the people who did wanted to beam each other money at lunch. The team needed a different lever — and found it in email.
In late 1999 Confinity launched PayPal, a service that let anyone send money to any email address. The recipient got a message: someone has sent you $X — click here to claim it. To claim the funds, they had to open an account. Every payment recruited the next user. The product was viral not because of a clever trick but because of what money fundamentally requires: a second person. Email, which already linked everyone, became the rails.
The service landed inside eBay’s ascent. Sellers with no credit history and no merchant account had always struggled to collect payment from strangers. PayPal solved the problem without permission: sellers started adding “PayPal accepted” to auction listings on their own. By the end of 2001, eBay’s check-payment share had dropped from about 80 percent in late 1999 to 50 percent — even as total eBay transactions surged — and PayPal was processing roughly 100 million online payments a year, two-thirds of them through auction sites (Federal Reserve Bank of Chicago, August 2002).
In March 2000, Confinity had merged with X.com, the rival online-bank that Elon Musk had founded a few blocks away. By October, after a board dispute, Thiel had replaced Musk as CEO and the company had committed itself entirely to payments under the PayPal name.
To accelerate growth, the team built what may have been the most expensive referral campaign in consumer internet history to that point. The program started at $20 for signing up and $20 for each friend recruited; it dropped to $10, then to $5, but even at $5 it drove 5 to 6 percent daily growth in the service’s third month. By September 2000, PayPal had five million users. Six months earlier it had one million. Thiel later put the total cost at $60 to $70 million (Aakash Gupta, “PayPal: The Original Product Growth Company”).
Fraud was the tax on that growth. PayPal’s fraud rate in 2001 ran at 0.66 percent — ten times the credit-card industry average — as international hackers systematically drained accounts through the same email rails the service depended on. Levchin led the counter-fraud engineering effort personally, building probabilistic detection systems that eventually contained the losses. The expertise would later seed Palantir.
eBay gave up trying to dislodge the thing its own sellers had chosen. In October 2002 it acquired PayPal for approximately $1.5 billion in stock (Wikipedia). The company had proved something simple and durable: a payment is information, and information moves freely. Everyone who has ever tapped “pay” on a phone has been answering that first email.
