Diabetes coaching startup becomes health tech's big IPO test

• Business Insider reported that the company could be valued at up to $2.5 billion.
• But while it brought in $68 million in revenue last year, it posted a net loss of $33 million.

Backdrop: Livongo's main source of revenue is self-insured employers, which hire it to monitor and coach employees with chronic diseases — especially diabetes.

• It said in an SEC filing that its services save over $1,900 a year in gross medical expenses for diabetes patients.
