ZocDoc, which helps users book doctor appointments online, said on Thursday it raised $130 million in funding, valuing the U.S. digital healthcare company at $1.8 billion. The funding was led by Baillie Gifford and Atomico, with participation from existing investor Founders Fund.

The proceeds would be used to develop products and expand beyond its scheduling capability, the company said. (bit.ly/1J6Tspr)
