Groupon co-founder Eric Lefkofsky just raised another $200 million for his newest company, Tempus
When serial entrepreneur Eric Lefkofsky grows a company, he puts the pedal to the metal. When in 2011 his last company, the Chicago-based coupons site Groupon, raised $950 million from investors, it was the largest amount raised by a startup ever. Lefkofsky seems to be stealing a page from the same playbook for his newest company, Tempus.
