“A simple typo gave Michael Ivey the idea for his company. One day in the fall of 2008, Ivey’s wife, using her pink RAZR phone, sent him a note via Twitter. But instead of typing the letter d at the beginning of the tweet — which would have sent the note as a direct message, a private note just for Ivey — she hit p. It sparked a brainstorm. That’s how you should pay people, Ivey publicly replied. Ivey’s friends quickly jumped into the conversation, enthusiastically endorsing the idea. Ivey, a computer programmer based in Alabama, began wondering if he and his wife hadn’t hit on something: What if people could transfer money over Twitter for next to nothing, simply by typing a username and a dollar amount? Just a decade ago, the idea of moving money that quickly and cheaply would have been ridiculous. Checks took ages to clear. Transferring money from one bank account to another could take days, as banks leisurely handed off funds, levying fees nearly every step of the way. Ivey got around that problem by using PayPal. But last summer, PayPal began giving a small group of developers access to its code, allowing them to work with its super-sophisticated transaction framework. Ivey immediately used it to link users’ Twitter accounts to their PayPal accounts, and his new company, Twitpay, took off. Today, the service has almost 15,000 users.”
