Founding Enterprise Account Executive - Atrix

Breakthrough medicines all start the same way: years of research, mountains of data, and countless decisions made by medical teams within the world's premier biopharma labs. These decisions then determine which treatments make it to market, how doctors learn about them, and ultimately which patients get access to life-saving care and when. We're at an inflection point. AI-powered drug discovery, precision medicine, and an explosion of real-world evidence have accelerated what's possible, but the teams translating science into patient access are drowning in data they can't use.
