Lehman Brothers has become the latest bank to strengthen its technology banking team by appointing two managing directors in internet investment banking. This is the second set of technology hires the bank has made in the past two weeks.

David Kostman is rejoining the firm as a managing director and head of global internet investment banking. During the six years he spent away from Lehman, he was chief operating officer and later chief executive at lingerie company Delta Galil USA. He was also chief operating officer at software maker Verticalnet.
