01 · Why this exists
The market created two fractures.
The first : your health is sliced into silos. One app for sleep, one for your heart, one for your plate, one for supplements, one for bloodwork, a subreddit for community. None of them talk to each other. None of them see you whole and so none of them is effective.
The second : platforms monetize your attention. Empty scores, feeds engineered to hold you back instead of moving you forward. The time you could spend on truly living your life is stolen from you.
Helix starts from a simple observation : everything is connected. Your night shapes your plate. Your magnesium shapes your stress. Your tribe shapes your consistency. Value isn't one more module. It's the link.
02 · The founder
Théo Sans grew up in Port-Leucate, in a modest family. Early on, he understood one thing: in a world where systems dictate reality, those who master how the parts connect gain the big picture and take back control. His mind, autistic and gifted, is neither a strength nor a weakness. It is a lens that breaks down structures, whether in electronics, human metabolism, or social organizations, revealing their weaknesses, leverage points, and opportunities.
He built several online communities, gathering up to 26,000 people around his interests. After graduating top of his class in Communication, he moved into electronics engineering, not out of passion, but out of necessity: to stop depending on other people's tools and to gain a holistic, hands-on understanding. At 19, he is building Helix alone, on a shoestring budget. Not a side project: an infrastructure where everything is connected, designed to help anyone truly optimize their health and everything it affects: energy, productivity, healthspan.
Existing solutions were either too simplistic, too opaque, or engineered to steal attention instead of saving time. Helix is not another wellness app. It is a system, built for those who refuse to leave their health to chance, opaque algorithms, or marketing promises. To him, biohacking is not a cult. It is a tool: taking back control of your body, your time, and the technologies you allow into your life.
03 · What it changes in the product
Every product choice is proof of the mission.
A score that learns your baselines, not a leaderboard. Missing data = lower precision, never a punishment.
Pillars that talk to each other: nutrition × stack × timing, not five apps glued together.
Anti-dopamine by design: pack first, challenges and IRL, not a network built to kill time.
Sovereignty: local-first health data, full export, European hosting. Educational optimization framework.
04 · The Helix Plan. From a health app to sovereign health infrastructure.
The plan. The whole plan, in order.
As you’ve likely noticed, most companies try to keep a lot of things under wraps, such as their long-term strategy... I’m going to disappoint you : I’m not a big fan of secrecy, especially not in the healthcare sector, and certainly not for a project like Helix, which is being built with and for its users.
In this plan, each phase can only begin once the preceding one has yielded the expected results : first trust, then revenue, then the model, then scale, and finally proof.

Phase 1. Now · The app, free.
The starting point is not one more app among 350,000. It's the unified score, sleep, movement, stack, nutrition, biomarkers, built for the hardest users to convince on the market: biohackers, athletes, neurodivergent people, chronic patients, founders. The ones who already track everything and believe nothing without a source.
And it's free. Not free for a launch window: free because charging this audience would mean sacrificing the one thing everything else depends on. Earning their trust produces two assets no budget can buy: a cohort of dense, longitudinal, consented data, and a reputation for rigor. It's that trust, not capital, that unlocks Phase 2.
Phase 2. Certification · Make the products pay, never the people.
If the user doesn't pay, someone has to: the products do. The supplements market exceeds $200 billion, yet the vast majority of health claims has never been validated by the EFSA. Nobody really knows what they're swallowing, and nobody plays the trusted third party.
Creapure didn't reinvent creatine: it guaranteed its purity, and it took the market. Helix applies that logic to the supplements and sensors it recommends: batch analysis, origin, purity, verifiable behind a QR code and backed by real Phase 1 data. We don't sell a promise, we sell certainty. This is the first revenue, and it's what pays for free.
Phase 3. The model · Doctors who teach, not an army that executes.
Serving companies with doctors doesn't scale: the more employees, the more doctors, and costs climb as fast as headcount. You don't put a horde of doctors behind a hundred thousand people. So we flip the order: before selling the service, we build the tool. A handful of doctors doesn't execute the recommendations, it teaches the model: on the volunteered, anonymized data from Phase 1, they issue their own, correct the model's, and every correction becomes training data. The doctor stops being a cost that grows with every client: they become an investment that improves the product for everyone.
Every health AI is trained on snapshots, a blood panel here, a questionnaire there: it has never watched a life unfold. The Phase 1 dataset, dense, longitudinal and volunteered, is precisely what can neither be bought nor caught up on. And no need for a giant model that knows everything: a specialized model, trained on medicine and nothing else, backed by a validated knowledge base, lighter, cheaper, hosted on European infrastructure. Sovereign end to end. Its job is to assist doctors, never to replace them.
Safeguards
How we keep the model from making things up.
A health model has no right to improvise. Reliability doesn't rest on one layer, but on five, stacked:
- 1
Constrained output. The model doesn't write free-form advice: it picks from a catalog of validated recommendations with bounded doses. Ranking, not inventing.
- 2
Mandatory sourcing. Every recommendation cites the study or data behind it. No source, no recommendation.
- 3
Hard rules. Interactions and contraindications are code, not AI: a forbidden output is blocked, no matter what the model thinks.
- 4
Judge model. A second model, on the same sovereign infrastructure, checks every output before delivery.
- 5
Abstention and escalation. At the slightest doubt or red flag, the case goes to a doctor. And a doctor continuously reviews a random sample of the rest.
Phase 4. Enterprise · Turn workplace health into a metric.
Disengagement and poor health at work cost about 9% of global GDP (Gallup): employers already pay for cosmetic wellbeing, they'll pay for the real thing. Employees get the app, medical follow-up and real support (supplements, training, nutrition, and so on): the Phase 3 model handles the routine, doctors keep the complex cases, and the cost no longer climbs with headcount. The employer never sees an individual: they get their teams' health baseline, its trend, and nothing below a minimum headcount. Medical confidentiality is not negotiable, and a team average is not medical data.
A dashboard that surfaces turnover, productivity and the health level of the teams. The benefits of a bonus evaporate within weeks, while those of a healthier team stay. And a team that ages badly loses its creativity as the company erodes. We start with the ones who already look after their health: sports clubs and desk work. The channel has existed since Phase 1, those users are founders, managers, freelancers, and they recommend what they use.
Phase 5. Industry · Where prevention is missing most.
Physical jobs stack everything: accident risk, occupational illness, shift work, and wages that leave little room for prevention. Public healthcare reimburses less every year, private cover costs more: for many people, the workplace becomes the last place prevention can still reach them.
Same core, adapted to the field: medical follow-up, supplements, healthy canteen food designed around real individual needs, sessions and local partnerships organized on site. For fewer accidents, fewer sick days, less wear from the job and better health. Here the plan makes rising profitability converge entirely with the common good (health, happiness).
Phase 6. Diagnostic support.
According to the WHO, chronic diseases account for three out of four deaths worldwide, and the vast majority of cardiovascular diseases, the leading cause of death, are preventable. The problem lies not in medicine itself, but in the scope of the perspective: an annual check-up captures a snapshot, whereas Helix captures the full movie. The Phase 3 model provides doctors with a medical history that a standard consultation cannot reconstruct, along with the ability to detect subtle early warning signs across assessments spanning years. An early signal triggers early action: fewer late diagnoses and fewer avoidable hospital costs. Helix does not replace doctors; it gives them back their time.
Phase 7. Long horizon · Where the margin for error is zero.
The most advanced preventive health in the world doesn't happen in a hospital: it happens 400 km up, where NASA monitors every astronaut's vitals continuously, microgravity eating about 1% of bone per month. Before orbit, there is closer ground: the bottom of a mine, a polar base, a submarine. The operators of those environments will never be able to build in-house what Helix will have: a predictive system validated across thousands of ordinary lives. Same core. Maximum stakes.
Phase 8. Sovereignty & the common good.
The last phase is the only one that earns nothing : and that's the point. Data stays the property of the people who generated it : never sold, never rented.
The trajectory
The app is European from day one: an app has no border, and neither does data sovereignty. The enterprise offering starts with France, the closest market and the only one where I can be in the room, then Europe, then the rest of the world.
Too long? Short version.
Basically, this is exactly what we'll do:
- 1Build the best health app, entirely free, with and for the most demanding users
- 2Certify the supplements and sensors we recommend, the Creapure way: the products pay, never the user
- 3Use this revenue to develop a sovereign, specialized AI model trained on anonymized health data volunteered by Helix users, taught and corrected by doctors
- 4Turn that accumulated experience into a full offering so companies can help their employees optimize their health, with an employer who measures teams without ever identifying a single individual: the model handles the routine, doctors the complex cases
- 5Extend that offering to physical jobs, where accidents, wear and the absence of prevention cost the most, for workers and companies alike
- 6Adapting this AI model to the medical field to facilitate the detection of health issues, leveraging the model's ability to spot weak signals alongside long-term monitoring. Assist doctors, never replace them. The result ? Better, more cost-effective care driven by preventive health.
- 7Extend the application of Helix solutions to complex fields where health is paramount: mines, isolated bases, then space.
- 8Give the data back to the people who produce it. Forever.
“Optimizing isn't performing for performance's sake. It's taking back control of your time, your body, and the tools you use.”
