ZocDoc, a US-based online medical treatment booking service, is raising a series D round that is set to top $150m, according to filings seen by VC Experts.
The precise amount targeted by ZocDoc is $152.6m, and the round will likely feature existing investors including DST Global, the investment fund spun-out of internet company Mail.ru, and venture capital firm Khosla Ventures.
The round is set to value ZocDoc at as much as $1.6bn. Insurance firm Aetna reportedly offered to buy the company in September 2013 for just $300m.
DST Global invested $50m in ZocDoc’s series C round in 2011, which Goldman Sachs boosted by a further $25m a month later. Prior to the latest round, ZocDoc had raised $95m from backers also including Founders Fund, SV Angel, Marc Benioff and Jeff Bezos.
News of the fundraising comes just weeks after the company launched ZocDoc for Business, a premium version of its service that it is offering to employers in order to expand its revenue channels.
“For years, employers have been asking us for a premium offering, and we’re pleased to deliver this customized service to them,” ZocDoc CEO Cyrus Massoumi said at the service’s launch. “The introduction of ZocDoc for Business highlights our growth as an evolving platform, and we’ll continue to roll out innovative products and features to new audiences.”
