People are turning towards health and fitness as a lifestyle, it's as much of a hobby as going to the pub for anyone my generation or older.
Now, people want to track everything:
Sleep
Glucose
Nutrition
Heart Rate Zones
People are slowly moving towards VO2 max tests, DEXA scans, biological clocks, epigenetics.

The global wellness economy has gone from $3.72 trillion (2015) → $6.8 trillion (2025). Nearly doubling in 10 years, and growing twice as fast as global GDP.
It's expected to hit $9.8tn by 2029.
If wellness were a country, it would be the third-largest economy on Earth behind the US and China.
Over the last 10 years it's massively changed:
Dietary supplements have grown ~8–9% year on year — currently worth ~$210bn
Hyrox participation is up +1,000% in 5 years
25% of brits are now part of a fitness community
Running clubs increased by 59% in 2024
41 million have used GLP-1s in the US
Infrared saunas ~10% a year growth and worth ~$2bn
Longevity supplements ~$29bn, anti-aging supplements ~$5bn
═══════════════════════════════════════════════════════
The only things that are actually moving faster are AI and Electric vehicles.
It's an interesting divergence in the world, although AI and Longevity are clearly highly complementary.
Market | CAGR | vs longevity |
|---|---|---|
AI | ~28–30% | Way faster — different league |
Electric vehicles | ~27% | Way faster |
Cloud computing | ~12–16% | Faster |
Digital longevity | ~12.8% | — |
Longevity (core) | ~9.4% | — |
Wellness (overall) | ~6–7.6% | Slower |
Pharmaceuticals | ~6% | Slower |
Global GDP | ~3.3% | 3× slower |

Half of what people now spend money on didn't exist 10 years ago, and a lot of it is pretty mad when you write it down:
A sleep ring company is worth $11 billion
People are swallowing molecules (NMN) that weren't available in 2016
Sitting in ice baths for as long as we can
Blasting ourselves in Saunas with ice packs on our nether regions
Increasing our testosterone levels artificially to higher than they were when we were 18
Wearing glucose monitors you couldn't legally buy without diabetes until 2024 for fun
Taking molecules that at the wrong dosage cause significant danger (rapamycin etc)
Injecting 'animal' molecules, or untested black market peptides we heard about on instagram
Sub-market | Size now (2025) | Growth per year | The 10-yr story |
|---|---|---|---|
Biohacking | ~$28–45bn | ~16–19% | Didn't exist in 2015. |
NAD+/NMN supplements | NMN ~$409m · NAD precursors ~$876m | ~14% | No-one mainstream before Lifespan. |
Cold plunge tubs | ~$355m | ~8% | Exploded post-2020 |
Wearables | $94bn market | Whoop $10bn val · Oura raised $900m | Oura founded 2013; Whoop 2012 — both went from startup to billions this decade. |
Continuous Glucose Monitors | $13bn → $31bn | ~15% | The consumer version is brand-new — you couldn't buy one without diabetes until 2024. |
An entire optimisation economy materialised from nothing — some proven, some in its infancy. People are so interested in self improvement, tracking, optimisation.
But hardly anyone can explain what most of it actually means.
Has anyone tried to get to grips with the science of HRV (Heart Rate Variability)?
We all want to improve it, but we don't really know why?

Everything we track correlates to something in your bloodwork:
Sleep → cortisol, fasting glucose, testosterone, inflammation
Glucose → HbA1c, fasting insulin, HOMA-IR
Nutrition → ApoB and lipids, omega-3 index, vitamin D, B12, ferritin
Heart rate zones → resting heart rate, lipids, inflammatory markers
VO2 max → haemoglobin, ferritin, cardiometabolic markers
DEXA → testosterone, IGF-1, vitamin D, metabolic markers
Biological clocks & epigenetics → largely driven by your inflammatory and metabolic blood markers
Everything here is shaped by what's in the blood.
Wearables give you a number. CGMs give you a number. A blood panel gives you 40 numbers and a wall of "normal".
None of them tell you what matters most for you, why, or what to do first.
This is what I'm trying to solve with Revi — starting with Longevity Bloodwork.
