Dave Asprey

Asprey worked in the IT industry for companies that included Bradshaw and 3Com. He taught and ran the Internet and web engineering program at the UCSC Silicon Valley Extension, in which Asprey created one of the first working instances of cloud computing. Later, he joined Exodus Communications as director of strategic planning, where he co-founded the company's professional services group.

His first startup was an early-stage e-commerce company founded around 1993, which was featured in Entrepreneur magazine. Eventually, the company delivered products to customers in ten countries, including Australia, the United Kingdom, South Africa, and several parts of Asia, making it one of the first worldwide e-commerce businesses.

Asprey was the director of product management for a Silicon Valley startup called NetScaler, which was later acquired by Citrix Systems. After working at Citrix, Asprey served as the vice president of marketing for Zeus Technology and later, vice president of technology and corporate development at Blue Coat Systems. He then became an entrepreneur in residence at Trinity Ventures before co-founding a company called Basis. Asprey was the vice president of cloud security for Trend Micro before he left to run his own business full time.

Asprey tried a vegan diet for six months in the early 2000s, but then returned to eating animal source foods. He has criticized veganism, stating that it can increase the risk of vitamin B12 deficiency and has suggested that it is "hard to get enough high-quality protein on a vegan diet". Asprey promotes the consumption of organic, grass-fed meat.

Asprey has stated that he expects to live to one hundred eighty years of age. As of 2021, he claims to have spent at least two million dollars on "hacking his own biology", including having his own stem cells injected into himself, taking one hundred daily supplements, following a strict diet, bathing in infrared light, using a hyperbaric oxygen chamber, and wearing special lenses when flying or using a computer. Asprey believes biohacking has benefited his sexual health, having kept an ejaculation journal for a year.

Asprey met his wife, Lana Asprey, a physician, at an anti-aging conference, and they lived in Vancouver Island, Canada. He claimed that following the Bulletproof diet helped his wife with her polycystic ovary syndrome. In 2021, Asprey and Lana divorced, after which Asprey moved from his thirty-two–acre farm in Canada to Austin, Texas.

Asprey supported President Donald Trump's nomination of Robert F. Kennedy Jr. to United States secretary of health and human services (HHS). He expressed hope that Kennedy would remove FDA regulations, believing that doing so would lead to a "dawning of a new age of biohacking". He echoed Kennedy's distrust of research funded by "Big Pharma", stating, “I want the right to look at all the data, and I want the right to make the decision of what works for me.”
