According to industry reports 1), 2), the longevity sector pulled in a whopping $8.49 billion across 331 deals in 2024—a sharp rebound and strong signal that this isn’t hype but a high-potential category. Meanwhile, HealthTech overall is flexing too: in the first half of 2025, U.S. and European startups raised $7.9 billion, led by AI-powered health tools.3) Much of that momentum hits longevity platforms offering rich data loops, remote diagnostics, and actionable insights. Who’s writing checks? A short roster from recent deals tells the story: Lightspeed, General Catalyst, Lakestar, and Atomico led a $260M round into full-body scanning startup NEKO Health, and a16z Bio + Health led Function Health’s Series A. And then consider Clinique La Prairie, launching a €100M Longevity Fund aimed at companies with near-market digital tools—wearables, diagnostics, nutra-tech, and AI platforms getting real now.
Five Pillars of Digital Longevity—and the Startups to Watch
Here’s how the space breaks down—and the game-changers that represent each bucket from our enriched vendor list.
1. Biomarker & Aging Clocks
What they do: These platforms measure how fast (or slow) your body is aging using epigenetics, proteomics, glycans, and other multi-omic data streams. They provide a biological “age score” that can be tracked over time, making longevity measurable rather than philosophical. Examples:
- Tally Health and epiAge bring epigenetic testing into the home, with cheek or saliva swabs that return actionable biological age reports.
- GlycanAge offers a unique immune-related biomarker approach through glycobiology.
- Zymo Research’s DNAge applies the Horvath methylation clock in a consumer-ready format.
- Deep Longevity’s SenoClock® combines multiple biomarker layers—including bloodwork and psychological data—into a SaaS platform.
- Gero and its collaboration with Scripps use AI and physics-based models to map aging trajectories, even identifying candidate compounds to slow the process.
- Epiclock and Vero represent the next wave, with genotyping and proteomics solutions that promise more dynamic and organ-specific insights.
- Epigee – offers rapid, at-home DNA methylation testing via dried blood spots, delivering biological age insights in under a week and enabling individuals and clinicians to track aging trajectories over time.
2. Preventive Health & Lifestyle Optimization
What they do: Longevity here is about guidance—turning biomarker data into everyday coaching on diet, exercise, stress, and supplementation. The best platforms combine personalized insights with clinically backed interventions: think “personal health OS” that lives in your phone. Examples:
- Function Health has built a membership model around large-scale biomarker testing, helping members track >100 health markers regularly.
- Lifeforce blends diagnostics, telehealth, and personalized supplementation, particularly around hormone and metabolic optimization.
- Superpower raised significant funding to expand its AI-driven longevity coaching platform.
- AVEA positions itself squarely in longevity supplements, paired with diagnostic feedback loops.
- AgelessRx functions as a tele-longevity clinic, prescribing age-related therapeutics such as metformin, rapamycin, and NAD+ boosters.
- Thorne brings consumer supplements into the mix, pairing their formulations with longevity-centric tests and partnerships.
3. Early Detection & Screening
What it does: These solutions look for problems before symptoms arise, using scans, advanced diagnostics, and digital platforms to track health status over time. Early detection is crucial to extending healthspan by catching disease processes at the earliest possible stage. Examples:
- NEKO Health, backed by Spotify’s Daniel Ek, offers full-body AI-powered scanning clinics and has scaled rapidly with investor confidence.
- Prenuvo provides MRI-based preventive scanning to create a baseline and spot silent pathologies.
- Biograph develops diagnostics for continuous longitudinal tracking.
- Healthy.io turns smartphones into diagnostic tools with at-home urine testing.
- Loovi tracks long-term metrics such as ApoB, VO₂ Max, and inflammation, key indicators for aging-related risk.
- LongevityEHR serves as a digital clinic backbone to capture and analyze longitudinal biomarker data.
- SiPhox Health is building mail-in and countertop blood testing devices to make repeat biomarker monitoring convenient and affordable.
- Q Bio – builds digital “whole-body digital twins” using rapid MRI, genomics, and continuous data, designed to detect aging-related risks and track health changes over time.
- Fountain Life – operates precision diagnostics centers offering advanced imaging and biomarker testing to identify diseases and age-related decline years before symptoms appear.
4. Therapeutic Discovery & Geroprotectors
What it does: This category isn’t just about creating drugs in a lab—it’s about building the digital intelligence layer that identifies, validates, and prioritizes geroprotective interventions. These platforms harness AI, large-scale datasets, and predictive modeling to map out which compounds or pathways could extend healthspan, without being biotech developers themselves. Examples:
- Insilico Medicine – operates as an AI-driven discovery engine, modeling age-related pathways and predicting candidate compounds that could slow aging.
- AgeXtend – uses advanced computational tools to forecast and validate potential geroprotectors, accelerating the preclinical prioritization process.
- Longevity.AI (Longevity International) – provides one of the largest databases and mapping platforms for longevity biotech and geroprotector pipelines, serving as infrastructure for researchers and investors.
- BioAge Data – specializes in mining omics datasets (genomic, proteomic, metabolomic) to uncover biological signatures of aging and link them to potential interventions.
- Rejuve.AI – applies decentralized AI to global health data, creating predictive models for interventions that may extend healthy years of life.
- Aging Analytics Agency – acts as a market intelligence and analytics hub, curating clinical, scientific, and investment data around geroprotector development worldwide.
5. At-Home Testing & Real-Time Vitals Tracking
What it does: These tools enable people to continuously measure the vital signs most predictive of long-term health, creating early warnings and lifestyle feedback loops that support longer, healthier lives. Examples:
- Eko Health’s AI-powered stethoscopes detect early cardiac and pulmonary issues, preventing chronic disease progression.
- CardiacSense provides wearables that monitor heart rhythm and oxygenation—vital metrics for aging populations at risk of cardiovascular decline.
- Empatica’s research-grade wearables help track stress, sleep, and neurological health, all tied to longevity outcomes.
- Hexoskin’s biometric shirts record ECG and respiration data, building long-term profiles of cardiovascular and respiratory function.
- Tellihealth supplies connected monitoring devices that allow clinicians to follow aging patients remotely, extending independent living years.
It’s worth mentioning that myriad solutions fit into this category, even if they don’t explicitly mention longevity in their use case. Take **CONNEQT Health, **for instance, which delivers connected blood pressure and vascular health monitors for at-home use. Though its selling point is enabling continuous cardiovascular tracking, it supports longevity by preventing undetected age-related risks. Fitness trackers, CGMs, and other health metric tracking devices and tools certainly fall into this category as well.
Why Investors Are All In, and Where It’s Going
1. Money magnet status: Longevity’s $8.5B haul last year isn't random. Healthtech is rebounding: 2025’s first half alone hit $7.9B. AI is central, accelerating everything from diagnostics to predictive coaching.
2. Data is the moat: Startups like NEKO aren’t just selling products—they build continuous, longitudinal health data that gets smarter every day, making churn harder and valuation stickier.
3. Hybrid consumer-clinic model: The winning play is neither pure DTC gadgets nor B2B platforms; it’s clinics meeting consumers. Function Health adding imaging, NEKO expanding across borders—these are signals of a future where preventive longevity lives in both gym bags and ORs.
Bottom line: Digital longevity is no pipe dream. It’s a high-growth, high-density overlap between data, prevention, and human desire to live better, longer. If you're investing, focus on where data meets design, science meets scaling, and habits meet hardware.
