It’s hard to imagine a better use for AI than @openevidence.

Daniel Nadler and his world-class team at OpenEvidence are building what I believe will become an AI-era treasure—a life-saving resource for doctors, patients, and their families.

I can’t imagine the future without it.

This year, more than 100 million Americans will be treated by a doctor who has used OpenEvidence. Word of mouth has propelled @openevidence into 10,000+ hospitals and clinics, helping healthcare providers access, evaluate, and apply the world’s medical knowledge. We’re proud to co-lead their Series B alongside @GVteam as they redefine evidence-based care.

I'm thrilled to share the @speedandscale 2024 Global Climate Tracker. It shows where progress toward net zero has been made, where it's lagging, and what we need to do to get there in time. Dig in.
