Six-time founder Ned David speaks with Venrock partner Camille Samuels about why he doesn’t particularly enjoy being an entrepreneur, but feels compelled to build companies, including newly formed Unity Biotechnology. They discuss Unity, and why Ned is passionate about eliminating the aches and pains of old age and extending human “healthspan.” He also shares how his hiring tactics have evolved from “The Bad News Bears” to “The Expendables” over the years, and why he wants to make his son proud.

Ned has founded a series of companies in the biotechnology and sustainable energy sectors, including Syrrx, Achaogen, Kythera Biopharmaceuticals, Sapphire Energy and now Unity, which designs therapeutics that prevent, halt, or reverse numerous diseases of aging.
