Healthcare
We create and invest in leading companies in therapeutics, medtech, and health IT & services.

Twenty Seven products and drugs approved
With another 8 drugs in phase 3. Typically, only 1 in 5,000 drugs makes it from idea to market.
Twenty three companies created from scratch
If we can't find a company solving an important problem, we create one ourselves - just like we did with Innovent, Denali, and Beam to name a few.
Nearly two billion dollars over seven funds
Without the pressure of fundraising from outside investors, we're privileged to champion companies that help heal the world.
