Timothy Ferriss, born 1977, is author of the bestseller „The 4-Hour Workweek“ which has been published in 35 languages.

In 2001, aged 23, Tim founded BrainQuicken, a San Jose-based online company that sells sports nutrition supplements. He sold the company in 2009 and is now an angel investor.

Wired magazine has called Tim "The Superman of Silicon Valley" for his manipulation of the human body. He is a tango world record holder, former national kickboxing champion (Sanshou), guest lecturer at Princeton University, and faculty member at Singularity University, based at NASA Ames Research Center.

When not acting as a human guinea pig, Tim enjoys speaking to organizations ranging from Nike to the Harvard School of Public Health.
