How the science behind reverse-aging could theoretically work, as Coinbase founder raises $40 million in a bid to make it reality

NewLimit — a startup spearheaded by Coinbase founder Brian Armstrong—is set to give the goal a shot. On Tuesday the company announced it had raised $40 million in a Series A round from Kleiner Perkins and other venture firms — and from prominent investors like former Google CEO Eric Schmidt and Y Combinator CEO Garry Tran, Fortune’s Jeff John Roberts reported.

Armstrong declined to make specific predictions about how many years the company’s research may extend life. Instead, he emphasized that its focus is on “healthspan” versus “lifespan”—a goal that centers on quality of life, not length.
