Business-to-business community site Zubican has been purchased by performance-based online marketer Inuvo. Terms of the acquisition were not disclosed, although Inuvo says it will pay a royalty based on a “percentage of the gross profit derived from the site over a four-year peirod.” Zubican, which launched in 2008, had raised an undisclosed amount of backing from investors including Athenaeum Capital, Pasadena Angels, and Tech Coast Angels.
