BulidNet Inc.

DURHAM -- BulidNet Inc., which matches home builders and suppliers online, wants to raise as much as $230 million in an initial public offering, the biggest ever for a Triangle tech company. With a head count of 868, the 4-year-old company is already bigger than most dot-coms. But in at least one respect it's little different than its Web kin: It has lost money since birth, including $68.6 million last year.
