Move, Inc., the parent firm of Realtor.com, said Thursday afternoon that its CFO, Rob Krolik, has resigned in order to become CFO of Yelp. Move--which is based in Campbell, California, but still has operations in Southern California, in Thousand Oaks--said the firm is now searching for a new CFO. Yelp is rumored to be heading towards an IPO, so the addition of Krolik and his expertise as a public company CFO is expected to help the firm in its efforts.
