(Bloomberg) -- Collective Health Inc. is trying to raise moneyfrom strategic and financial investors in a round that would valuethe do-it-yourself health insurance startup at $1 billion,according to people familiar with the situation.

Goldman Sachs Group Inc. is helping the San Francisco-based firmraise another $100 million or so, according to the people, whoasked not to be identified talking about private fundingefforts.

Collective Health has raised more than $100 million so far, withthe most recent infusion coming from Alphabet Inc.’s GV, FoundersFund and others in late 2015. A company spokeswoman declined tocomment.

The push comes as investors continue betting tech startups will disrupt the multibillion-dollar insurancesector through more efficient underwriting and new practices likecrowdsourcing and on-demand coverage, which lets users pay forinsurance only when they need it.

Investors backed a record 174 insurance startups last year, anincrease of 40 percent from 2015 and 85 percent from 2014,according to research firm CB Insights.

Founded in 2013, Collective Health acts as a carrier forcompanies choosing to manage their own employees’ health insurancecoverage. Instead of working through a large insurer like AetnaInc. or Kaiser Permanente, the startup administers medical,pharmacy, dental and vision claims on a single platform on behalfof its customers.

Competing against hundreds of third-party insuranceadministrators in the U.S., Collective Health aims to streamlineand digitize a process that is still largely fragmented andoffline. Collective clients, which pay $35 to $50 a month peremployee depending on the services, include Activision BlizzardInc., Zendesk Inc., EBay Inc. and Palantir Technologies Inc.
