US-based online health network provider PatientsLikeMe has received $26m in a funding round co-led by Optum Ventures, the corporate venturing arm of healthcare and pharmacy services provider Optum.
Hambrecht Ducera Growth Ventures, PBM Capital and Alta Partners also co-led the round, which also featured commitments from Symphony Ventures and individual investor Jeff Leerink.
Founded in 2004, PatientsLikeMe operates an online networking platform for users to share information on their health, symptoms and treatment outcomes with other members with the same conditions.
The company said its platform is used by more than 830,000 people with over 2,900 medical conditions.
PatientsLikeMe has also developed a clinical research platform which provides real-time insights on medical conditions for research organisations.
In 2007, PatientsLikeMe received $5m for its series A round led by Collaborative Seed and Growth Partners, which invested alongside private equity fund Invus.
The company raised $8m from one undisclosed investor in 2010 and $12m from unnamed backers in 2013, according to securities filings.
PatientsLikeMe secured $100m from digital health technology developer iCarbonX and Invus, as a part of iCarbonX’s Digital Life Alliance initiative, in 2017.
Prior to this investment, the company raised over $25m from Invus, Collaborative Seed and Growth Partners, CommerceNet and Omidyar Network.
