LivingSocial, a US-based discount coupon company in which online retailer Amazon invested $175m in December, has taken its total raised to more than $600m.
The company said it had raised $400m from an undisclosed mix of new and existing public and private investors, compared to $950m raised by peer Groupon earlier this year.
The round values LivingSocial at about $2bn, according to press reports, and news provider Fortune said mutual fund manager T Rowe Price and venture capital firm Institutional Venture Partners had invested.
Tim O’Shaughnessy, chief executive and co-founder of LivingSocial, said: "With this investment we’ll bring LivingSocial to tens of millions of new members around the world and introduce innovative ways to connect our members to merchants."
LivingSocial has 26 million members in 206 daily deal markets and 46 Family Edition markets.
