Marc Samwer was born in Munich, Germany, Germany, is Cofounder, Rocket Internet. Marc Samwer is #1890 in List Billionaires People In The World. Marc Samwer and his brothers Oliver and Alexander Samwer make it onto the billionaires list for the first time in 2015 after taking Rocket Internet, their Berlin-based tech incubator public in October 2014. The oldest of the brothers, Marc does not take part in day-to-day management of the company, leaving that to Oliver. Collectively, the brothers own a little more than 40% of Rocket, which was valued at more than $8 billion at the time of its IPO. Inspired by the dot-com boom after spending time in the U.S. in the late 90s, the brothers created a German auction site, Alando, in 1999 which they sold to eBay for $43 million after only a few months of operation. That was followed by the creation of a mobile phone content provider Jamba! that was sold to Verisign in 2004 for $273 million. Founded in 2007 by the Samwers, Rocket has has gone on to rub many entrepreneurs the wrong way with its reputation for cloning tech companies. The strategy, however, has paid off. The company's first big success was CityDeal, a European daily deals clone that was sold to Groupon in 2010 for $170 million, while its most recent win was the initial public offering of Zalando, a Zappos-like online retailer that went public a day before Rocket. Following the CityDeal acquisition, Marc Samwer served as the head of Groupon's international business before leaving that role in April 2012.
