our founders

The modern world is a hostile place to live. Fast food, addictive algorithms, environmental toxins, and a broken health care system have most of us feeling run down and burnt out.

We all want to be healthy and look and feel our best, but how? It’s all so confusing.

We have been building a new world, one that takes care of you.

We started with Bryan’s body. A team of medical professionals, population-level evidence, and 1.5 billion data points later, Bryan became the most measured person in history and overhauled his broken-down 42-year-old body into achieving top 1% metrics in muscle, cardiovascular health and sexual function.

Kate has now started the same journey to better understand the longevity of female biology. The same methodical, scientific process.

Immortals is built on the principles of measurement, population-level scientific evidence, and personalization.

What we’re building is brand new. We call it your Autonomous Health.

Cars now drive themselves, and software now writes itself. Your health is next.

It can work no matter your age, race, or gender. The biggest levers for longevity are free.

Our commitment to you is care. We are building a new standard for ‘care:’ we promise to care for you as we’d care for ourselves, and our loved ones. That’s nearly impossible to find in the world.

We invite you to join our community. Doing things together is twice the joy and half the sorrow.

Everything is in one place: nutrition, longevity prescriptions, GLP-1s, sleep, skin care, hair care, and more.

Home base is the Immortals App (COMING SOON). That’s where we’ll track biomarkers, have your protocols, and keep you on track to achieve your health goals.

We are Immortals. We hope you will join us.

— Bryan & Kate

Changed my life

As someone in tech, I spend most of my day sitting or standing at a screen. Since starting Blueprint in 2025, I've lost over 50 lbs and finally feel in control of my health. I can't thank Bryan enough for creating this.

Bringing balance to body and mind

I've been taking Longevity Mix and Essential Capsules consistently for a month. I've noticed that I am more alert, focused, and have better memory. My sleep has also improved. I fall asleep more effortlessly, my sleep is deeper and more rejuvenating.

Best protocol for your health

I started this protocol just over a year ago and I’m now seeing amazing results in weight, energy and overall health. People are noticing the changes and asking what I'm doing. Game changer at 50.

Mind Blown

I recently purchased Longevity Mix. This product has given me near instant improvements to my mood, sleep, and energy levels throughout the day. Having changed nothing else in my daily routine, I can without a doubt contribute these immediate improvements to Longevity Mix.

Both Blueprint and Immortals were founded by Bryan Johnson and Kate Tolo, with the same team of longevity experts.

Bryan Johnson is the world's most measured human.

Bryan's best measured epigenetic speed of aging is 0.48 (average 0.5) — ranked #1 of 5,677. He built the protocol that produced those results, then published it openly: the full Bryan Johnson Blueprint protocol, free for anyone to follow.

Before Immortals, he founded Braintree, which acquired Venmo and was sold to PayPal in 2013. Along with Kate Tolo, he is the founder of Immortals and Blueprint.

Bryan Johnson's team of longevity experts built an algorithm to run his body. It reads his data and tells him how to build his protocol based on how his body responds. BryanAI gives everyone access to that same framework.

Connect any wearable. Upload your biomarkers. BryanAI reads your data, cross-references it against Bryan's protocol and population-level research, and helps you build a personalized longevity protocol with daily insights, in plain language. It's free and adapts to your biology. No clinician visit required to start.

Yes. The Immortals app is free. Uploading biomarkers from any provider is free.

Biomarker panels, longevity prescriptions, and supplements are available to purchase through Immortals, but none of these are required to build a personalized longevity protocol in the app. Start with what you already have.

You don’t need biomarkers to start using Immortals. You can connect your wearable, upload any health data captured by your phone, whatever you’re able to provide.

BryanAI helps you build a baseline longevity protocol from sleep, heart rate, HRV, and activity metrics. That's enough to begin. When ready, you can purchase a biomarker panel through Immortals or upload results from any lab you've already used (the app reads any format from any provider). The protocol insights get more precise with more inputs.

Immortals supports all major wearables.

Supported devices include Oura, Whoop, Apple, Fitbit, Eight Sleep, Dexcom, Freestyle Libre, Ultrahuman, Polar, Withings, Google Fit, Strava, Peloton, Wahoo, Hammerhead, Omron, Cronometer, and Beurer. Upload biomarkers from any lab in any format. BryanAI reads it all.

Most medicine is reactive. You wait for symptoms, then treat the disease.

Longevity medicine measures the biomarkers that signal early risk factors sometimes decades before symptoms develop. The goal of longevity medicine is routine measurement and early intervention to help detect and avoid age-related decline and chronic illness from developing in the first place and extend the years you’re actually healthy. It’s proactive rather than reactive. The tools of longevity medicine are: comprehensive biomarker panels, wearable data, personalized supplementation and prescriptions, and other data-backed longevity interventions.

Immortals is the longevity medicine platform built on Bryan Johnson's protocol.

Chronological age counts years. Biological age measures how your body is actually performing based upon biomarkers.

Two people born the same year can have biological ages that differ by 20+ years. The gap is determined by many biomarkers types… things like body composition, blood work, and DNA methylation patterns. Bryan Johnson's biological age is significantly younger than his chronological age.

Most of Bryan Johnson's longevity protocol is free. He openly publishes all of his data and protocols on sleep, nutrition, and exercise.

Biomarker panels, longevity medications, and Blueprint supplements are available to purchase through Immortals as optional add-ons, but are not required to follow the protocol.

Immortals is the only longevity care platform built on Bryan Johnson's protocol. It combines biomarkers, wearable data, prescriptions, and supplements into one app, with BryanAI personalizing every recommendation to you.

Most longevity apps are either tracking dashboards (data without action) or supplement marketplaces (action without data). Immortals connects the two. Connect any wearable, upload biomarkers from any lab, and BryanAI will build a longevity protocol calibrated to your biology, with continuous daily insights as your data updates.
