WSJ writes about Jeff Pulver’s new company:
Beginning today, closely held Tello will offer a service that will let workers see on their computers or mobile devices whether the person they are trying to reach is on an office phone or cellphone or is logged on to instant messaging. If the person is off the office phone, Tello can let others know how long ago he or she last made a call.
Mr. Pulver says Tello aims to extend the “presence” feature that users of instant messaging have come to rely on, letting them know when other users are logged on and available. “For the last three years, I’ve been telling people that presence is a $25 billion industry that we don’t know how to describe,” said Mr. Pulver, a co-founder of Vonage Holdings Corp.
Om Malik has more.
