I'm watching with interest the planned IPO of Marchex, Inc., a Seattle-based company started by the Russ Horowitz gang�-- the founders of Go2Net. These guys are excellent business aggregators. They make acquisitions and weave them�into a large, scalable business. Marchex is seeking $28 million (revised downward from their November S-1). Last year's revenues were about $22 million. Most of it came from Ah-ha.com, a company that MyFamily.com once acquired and owned briefly.
