Imagine spending over $2 million each year simply to stay young. That’s exactly what Bryan Johnson, the 48-year-old founder of Braintree, is doing with his ambitious anti-aging experiment. He sold his payments startup to PayPal for $800 million and walked away with about $300 million. Now, instead of luxury cars or villas, Johnson channels his fortune into Project Blueprint, a self-funded longevity program that monitors dozens of his organs and tweaks his diet and lifestyle to reverse aging. His quest to live longer even earned him a spot in the Netflix documentary Don’t Die: The Man Who Wants to Live Forever.

Bryan Johnson’s Early Life and Education
Bryan Johnson was born in August 1977 in Provo, Utah. He grew up in neighboring Springville, the middle child of a divorced mother and a stepfather who owned a trucking business. Raised in The Church of Jesus Christ of Latter-day Saints, he served a two-year Mormon mission in Ecuador when he was 19. This disciplined upbringing and world-travel experience gave him a broad perspective on life.
After returning from his mission, Johnson pursued higher education. He earned a Bachelor’s degree in International Studies from Brigham Young University in 2003, then completed an MBA at the University of Chicago in 2007. Even as a student, he showed an entrepreneurial spark – he sold cell phones on campus and helped launch a failed voice-communications startup. These early ventures taught him business basics and set the stage for his future successes.
Age Clarification: Bryan Johnson’s age is often asked. In fact, how old is Bryan Johnson? He was born in 1977, so as of 2025 he is 48 years old.
Bryan Johnson’s Entrepreneurial Career
Johnson’s career took off in 2007 when he founded Braintree, a mobile- and web-payments platform. Within a few years Braintree was processing billions of dollars and even acquired the peer-to-peer payments app Venmo in 2012. In September 2013, PayPal (then part of eBay) bought Braintree for $800 million. Johnson walked away with roughly $300 million from that deal, instantly making him a multimillionaire and one of Silicon Valley’s rising stars.
- Building Braintree (2007–2013): Johnson bootstrapped Braintree from his home, growing it into a fast-scaling payments startup. By 2013 it handled ~$12 billion in annual payments. That September, PayPal acquired Braintree (including Venmo) for $800M.
- Post-Sale Windfall: From the sale, Johnson personally netted around $300 million. He famously told Inc. magazine that he achieved a goal he set at age 21.
After the Braintree exit, Johnson turned investor. In 2014 he poured $200 million into creating the OS Fund, a venture-capital firm for deep-tech startups. The OS Fund’s mission is to fund companies that “see beyond our lifetimes,” according to Johnson. He also founded Kernel in 2016, a neurotechnology company aiming to develop wearable brain-interface devices. By 2020, Kernel had raised over $50 million to build headgear that can measure and stimulate brain activity.
To summarize his major ventures:
- Braintree (2007): Founder/CEO. Built a mobile payments platform; acquired Venmo (2012) and sold to PayPal for $800M.
- OS Fund (2014): Founder/Manager. A biotech and deep-tech investment fund, seeded with ~$200M from the Braintree sale.
- Kernel (2016): Founder/CEO. Neurotech startup creating wearable brain-recording devices (raised ≈$53M by 2020).
- Blueprint (2021): Founder. His personal longevity venture (details below).
- Authorship: Between 2017 and 2019 Johnson authored two children’s science-fiction books (“Code 7” and “The Proto Project”), adding to his public profile.

Bryan Johnson’s Longevity Blueprint
After securing his fortune, Johnson shifted focus to human biology. In 2021 he began Project Blueprint, an intense self-experiment in longevity. His goal: to track and reverse his biological aging across dozens of organ systems. Johnson collects mountains of data — from genome scans to tissue health markers — and tailors his lifestyle to optimize them.
Johnson’s Blueprint initiative has made headlines for its extremes. He follows a highly regimented diet, takes hundreds of supplements, and even undergoes medical procedures to keep his body youthful. In fact, he spends about $2 million per year on health optimization. This includes things like IV nutrient drips, regenerative therapies, and custom supplements formulated by his team.
In the press, people often refer to this effort as the Brian Johnson blueprint (note the alternate spelling) when discussing his longevity experiments. Johnson himself says he’s trying to hit an “optimal state” where his body’s organs are as healthy as a young person’s. Reportedly, he even managed to reverse his biological age by about 5.1 years on certain epigenetic tests through Blueprint, though experts caution that long-term results remain to be seen.
- Launching Blueprint: In late 2021 Johnson publicly shared that he was tracking 140 health measures. His company, Blueprint, sells a few products (like a $4,700 “longevity mix” drink) but mostly serves as a research lab for his own anti-aging regime.
- Daily Regimen: Johnson’s routine is famously extreme. He eats precisely measured meals, avoids sugar entirely, gets near-daily workouts, and sleeps 8–9 hours. For Brian Johnson’s longevity plan, supplements like NAD boosters and melatonin are staples. He also performs monthly gluteal IV infusions and get frequent whole-body MRI scans to catch any decline early.
- Philosophy: Johnson’s longevity push is guided by his motto “Don’t Die,” an ideology he coined to emphasize healthspan over lifespan. He frames Blueprint as a public experiment: sharing his data and learnings in hopes others can benefit from science-based longevity practices.
Bryan Johnson’s Personal Life and Relationships
Johnson keeps his personal life relatively private, but a few facts are public. He grew up in a Mormon community and, as a young man, entered into a marriage that lasted about 13 years. In interviews he’s explained that this marriage was arranged through his faith, which was Bryan Johnson wife in name. Together, he and his first wife had three children. By 2014 Johnson had left the LDS church and divorced his spouse. (Media reports later identified singer-songwriter Taryn Southern as a long-term girlfriend he broke up with in 2020, though she was not his wife.)
Nowadays, Johnson is not married. He’s in a committed relationship with Kate Tolo, a neuroscientist and his co-founder at Blueprint. In 2025, Johnson announced on social media that he and the 30-year-old Tolo have been dating for three years. He publicly praised her as his “favorite person” and partner on this longevity journey. Despite the age gap, they are very supportive of each other’s work. Johnson has no current spouse on file and often refers to Tolo as his partner rather than wife.
- Family Snapshot: Married young (for 13 years) in a church-arranged marriage, father of three children. Divorced around 2014.
- Current Relationship: Dating Kate Tolo (scientist and Blueprint co-founder) since ~2022. They live together and collaborate professionally.
- Marital Status: Not married; the question “Bryan Johnson wife” can be answered by noting he has no wife now, only a girlfriend/partner (Kate Tolo).
Bryan Johnson’s Wealth and Financial Strategy
Johnson’s wealth is tied directly to his business success. Most media outlets estimate Bryan Johnson’s net worth to be around $400 million as of 2024. (Some reports even list the same figure for 2025.) These estimates come from the cash he made selling Braintree and growing his investments. Interestingly, Johnson himself is more modest about his fortune; in a public forum he mentioned his liquid net worth is “a couple hundred million” after allocating much to ventures.
Bryan Johnson Net Worth
The bulk of Johnson’s wealth came from that 2013 exit from Braintree. Financial sites and news sources round it to $400 million, which factors in the money he plowed into OS Fund, Kernel, and Blueprint. (For perspective, after the PayPal deal he had ~$300M in cash, and then funded new companies with much of it.)
Even though he spends aggressively on health and startups, Johnson still has substantial net worth on paper. His investments in startups (via the OS Fund) and biotech companies make up a significant share, meaning not all of his fortune is liquid cash.
How Did Bryan Johnson Get Rich?
Primarily through selling his company. In 2013, Johnson’s big payday was the PayPal acquisition of Braintree. He’d built Braintree into one of the fastest-growing fintech companies, making $4.6 million in revenue by 2010. When PayPal paid $800M for Braintree, Johnson personally netted about $300M after taxes. That windfall set the stage for his current lifestyle.
Other contributions to his wealth include:
- Investments: Johnson reinvested much of his exit cash. He put $200M into the OS Fund to back other startups, and about $64M into Kernel. These are mostly illiquid stakes.
- Blueprint Business: He’s also poured $20–$30 million into Blueprint’s wellness brand (selling supplements and consulting), though Blueprint was designed more as a personal project than a profit center.
- Book Sales: The two books he wrote for young readers added some revenue, though likely minor compared to tech deals.
- Other Ventures: Earlier failures (like a real estate project and a Skype-like startup) didn’t make him rich, but Braintree’s success did.
Media Presence and Public Image
Johnson’s unique story has drawn significant media attention. Major outlets have covered his journey from tech founder to “health-span” evangelist. He has appeared in interviews, podcasts and the documentary Don’t Die, bringing his ideas to a wide audience.
- Netflix Documentary: Johnson was the subject of Don’t Die: The Man Who Wants to Live Forever (2022), which follows his daily routine and philosophical quest to extend life.
- Published Works: He published two children’s books (2017 and 2019) blending science fiction with his vision of the future. He framed these as part of his mission to inspire the next generation.
- Interviews and Social Media: Johnson often shares insights on longevity and tech. He’s active on Twitter/X, explaining his regimen or discussing futuristic goals. Journalists from Fortune, People, Mint, and others have written profiles about him.
Conclusion
Bryan Johnson’s life blends the worlds of tech entrepreneurship and radical health science. He built a fortune by creating valuable payment companies, and now invests that fortune in himself – literally – through an experimental longevity program. By age 48, most people are thinking about retirement; Johnson is thinking about how to become “epigenetically younger.” His journey challenges conventional paths to wealth and wellness.
Bryan Johnson is a billionaire-by-exit turned biohacker. He made his money from Braintree’s sale and then chose to spend it on extending his life. Along the way he’s become known as a public face of anti-aging science. Whether he achieves immortality or not, his story offers a compelling case study of 21st-century ambition.
