History
The company was founded in 1994 as DistriVision by Tom Gonzales and his son, Tom Gonzales Jr. It was renamed Commerce One in 1997 after Mark Hoffman became CEO. In January 1999, the company acquired Veo Systems from Asim Abdullah for $300 million. In November 1999, the company acquired CommerceBid from Ramesh Balwani for $4.5 million in cash and 785,000 shares and the company partnered with General Motors to create an online marketplace.
