Shopping search and comparison site Become.com raised $8 million in Series D investment capital from the European Founder's Fund (EFF).

This brings total investment for Become.com's to $37.2 million. Prior to the EFF investment, it raised $17.5 million in Series C financing from TPG. The site has been profitable since the last quarter of 2007.

CEO and founder Michael Yang expressed an interest in using the money to expand into Europe. "We look forward to taking our unique, research-based approach to comparison shopping to the European market and providing the best shopping experience possible for its users," he stated.

Become.com provides product research data and purchase opportunities for 25 million products and 5000 merchants. It operates in North America and Japan.

The EFF finances online firms that aspire to do business in both North America and Europe. It has funded LinkedIn, Facebook and — just last month — Tremor Media.
