KowaBunga! is the latest firm to join the growing list of acquisitions made by CGI Holding Corporation.

CGI, which operates WebSourced and MarketSmart Advertising in the Triangle, announced Monday that it was buying KowaBunga Marketing, a provider of Internet marketing software and other technologies. The company is based in Westland, MI.

Unlike in other deals where CGI has disclosed the purchase price and information about stock offerings, details of the latest acquisition were not disclosed.

CGI stock (Amex: THK) closed at $5.10 on Monday, down 22 cents. The KowaBunga acquisition was disclosed before the markets opened. CGI is in the process of changing its name to Think Partnership.

KowaBunga offers affiliate marketing, search engine marketing and email marketing tools and services. The company was founded in 1996. Its founder, Todd Farmer, will remain with the firm, CGI said.

“This transaction emphasizes Think Partnership’s commitment to state-of-the-art technology and innovation in the affiliate marketing sector,” said Gerard Jacobs, chief executive officer of CGI. “Think Partnership is very fortunate to have new partners of the caliber of Todd Farmer and his team at KowaBunga.”

CGI has acquired several firms over the past year, including MarketSmart.
