Four years ago, on the TED stage, I announced a company I was working with at the time called Odeo.

They are President Philippe Kirsch (Canada), First Vice President Akua Kuenyehia (Ghana) and Second Vice President Elizabeth Odio Benito (Costa Rica).

One of the guys I hired was an engineer named Jack Dorsey, and a year later we were trying to decide which way to go with Odeo, and Jack presented an idea he'd been tinkering around with for a number of years that was based around sending simple status updates to friends.
