Jim Fowler, chief executive of Jigsaw, is fond of saying his Web-based start-up is following the Wikipedia formula.

Its database of 17 million contact records and 3 million company records is growing rapidly, Mr. Fowler notes, thanks to Jigsaw’s “community” of more than 1 million members who build and maintain the database. Its membership of registered users is expanding by 1,500 a working day.
