Andrew Shotland reports that local search and info company Grayboxx has sold its intellectual property to Bay Advisor. It seems like an odd coupling. I tried to get in touch with founder Bob Chandra to get an answer but have not been successful in my attempts. He is now at his new startup, Site605, which is doing human-authored web, or something along those lines. Grayboxx was aggregating data about local businesses, and its technology — in the demo, at least — seemed pretty impressive. The company didn’t get much traction, a problem not unique to Grayboxx, but a malady common amongst many consumer web services that launch with much fanfare.
