Timothy Ferriss was born on July 20, 1977, in East Hampton, New York.

In 2001, Ferriss established BrainQUICKEN, an internet-based nutritional supplements company. He later sold this company, then known as BodyQUICK, to a private equity firm in London in 2010. His experiences during this time formed the basis for his first major literary work.

These books collectively established his reputation in areas of productivity, fitness, and skill acquisition. He is also recognized for his podcast, “The Tim Ferriss Show,” which launched in 2014 and has achieved over one billion downloads. The podcast features interviews with prominent individuals across various fields.
Beyond his entrepreneurial and literary pursuits, Ferriss has engaged in angel investing and advised various technology companies.
