China’s leading daily-deals website Lashou Group plans to raise up to $100 million in an initial public offering on the Nasdaq to expand its marketing efforts and delivery systems, according to a filing to the stock exchange. Lashou, which was launched in March 2010, operates in 500 cities or towns in China. Its business model is like Groupon Inc, where users buy discounted deals from merchants who have revenue-sharing agreements with Lashou. China’s group buying sector is intensely competitive and saturated with more than a thousand group buying websites and Lashou faces an uphill battle to win a lion’s share, analysts say.
