Digital health has been a hot spot for investors.
Innovation in the space includes cancer treatments, telehealth, and digitizing health data. In 2018, digital-health startups raised $14.8 billion, and funding has increased almost every year since 2014, CB Insights said.
Eventually, though, startup investors want to see a return on their investment. For that to happen, the startups need to go public or get acquired by another company. Since 2011, 16 digital-health companies valued at at least $1 billion have gone public or been acquired, according to CB Insights. Nine of those deals happened in 2018.
Looking at the eight US companies that held initial public offerings, Business Insider evaluated the companies' stock-market performances. Four of the companies have gained since their IPOs, and four have declined.
