Hobsons, one of the major companies that helps colleges recruit, communicate with and retain students, this morning announced that it has purchased Intelliworks. Craig Heldman, CEO of Hobsons, said in an interview that he saw the combination expanding the reach of the company. Hobsons has many more college clients than Intelliworks -- about 2,300 vs. 300. But the focus of Hobsons in higher education has been undergraduate institutions. About two-thirds of Intelliworks' college clients are in graduate, continuing or executive education -- and area of potential growth now for Hobsons. Todd Gibby, the Intelliworks CEO, will join Hobsons as managing director for higher education. Financial details of the transaction were not released.
