Digital-health startup Livongo Health Inc. has filed to make an initial public offering expected to value the company at more than $1 billion.

The startup — co-founded by Chicagoan Glenn Tullman, former CEO of AllScripts — has hired Morgan Stanley, Goldman Sachs Group Inc. and JPMorgan Chase & Co. to serve as underwriters, according to the Wall Street Journal.

Livongo, based in Mountain View, Calif., previously raised $240 million through multiple rounds of VC investment. Investors include Kleiner Perkins Caufield & Byers, General Catalyst, Microsoft Corp. and Sapphire Ventures.

The company reported only $68.4 million in revenue in 2018, but it's sales have been accelerating.IN the first quarter of 2019, the company reported $32.06 million in revenue, compared with $12.46 million a year ago. For the quarter, it lost $14.96 million, compared with a net loss of $4.22 million a year ago.

Tullman — recently received a Dealmaker of the Year Award at the 2019 Aspire Dealmakers Conference earlier this month in Chicago — is executive chairman of Living. He co-founded the business in 2012 to provide glucose monitors and test strips for diabetes. It has since become a provider of wearable tech to monitor other conditions, including high blood pressure and excess weight.

Last December, Tullman turned over the reins of the company veteran healthcare technology executive Zane Burke.
