A year ago, Chas Christiansen, 25, had a problem many people around the country faced — he was out of a job. A veteran courier, he and former coworkers looked at how their peers in other parts of the world made a living by riding bicycles.

Starting off as an informal venture between Christiansen and a friend, TCB Courier was created to take bike messengers out of the financial center of San Francisco, delivering court filings and other legal documents, and into the cultural center in the Mission District.

Now, whether a customer wants a cheesesteak, a bottle of wine or even a pair socks, TCB Courier is, as Christiansen says, making it easy for “people to be lazy at 4 a.m.”
