What if we could use the power of artificial intelligence (AI) to understand and even influence our stress response? What if we could intervene before stress becomes chronic, and before it leads to chronic illness?

We’re entering a new chapter in human health, one where stress can be mapped, measured, and managed in real-time. Where health issues can be caught before they escalate, and where the right insight or micro-intervention can shift not just the course of your day, but your long-term health and wellbeing.

Making this possible is a new generation of technology, paired with real-time data and behavioural science. When applied to the workplace, we layer contextual signals to provide a deeper layer of understanding, allowing us to predict when stress moments occur and intervene before a crisis.

At WONE, this is our north star. We’re a Personalised Health Coach that turns stress into strength. We help employees regulate stress, build resilience, and unlock their full potential, because a healthy workforce is a high-performing workforce.

Here we explain how we're building the world's first Stress Coach, leveraging AI, behavioural science and multiple data inputs, and creating a new model of health that's preventive not reactive.

Multimodal Stress Measurement

Pre-existing methods tend to separate physical and psychological data, for example fitness trackers monitor HRV, sleep quantity and step count whilst wellbeing apps often rely on mood check-ins or journaling. But stress isn’t confined to one system, it shows up in our body, mind, habits, relationships and behaviours. If we want to manage stress, we first need to measure it in an integrated way.

Central to our solution is the WONE Index: a scientifically validated assessment of stress and resilience. Unlike traditional tools that focus solely on stress levels or resilience as a static trait, the WONE Index offers an integrated view. It uniquely captures both an individual’s current stress experiences and the dynamic, modifiable factors that support long-term resilience. 

The WONE Index simultaneously assesses:

• Current stress levels: stress across multiple life domains, including work-related pressures, personal challenges, burnout, and broader societal stressors.

• Resilience resources: drawing from decades of scientific research, we evaluate the key modifiable factors that influence an individual’s ability to cope with stress. These include emotion regulation skills, quality of social support, sleep and energy patterns, physical activity, dietary habits, sense of purpose, prosocial behaviour, and cognitive tendencies such as rumination.

This dual approach enables a far more precise and actionable understanding of an individual’s needs, empowering us to deliver highly personalised interventions that target both immediate stress and the long-term capacity to thrive. Rather than simply identifying who is at risk, the WONE Index guides each person on how to actively build their resilience, supported by our Stress Coach and personalised interventions.

Our unique methodology combines physiological data from wearable devices such as HRV, sleep quality and quantity and activity with a self-reported assessment to measure current stress and resilience constructs.

Our multimodal approach also blends contextual signals such as engagement with the WONE platform. We then calibrate these data points against well-established markers of resilience: emotional regulation, social connection, and purpose-driven behaviours.

“There’s no standard blueprint for integrating psychological and physiological data into a single stress score. That’s why we decided to build the world’s leading measure of stress , one that’s dynamic, contextual, and grounded in scientific rigour.”
Reeva Misra, Founder & CEO, WONE

This allows us to build a comprehensive profile of both the stressors an individual is facing, and their capacity to respond. From that profile, our system generates tailored recommendations that adapt to the user’s unique stress signature.

Pattern Recognition Across Time

Chronic stress rarely arrives all at once - it builds over time.

WONE’s AI engine will identify patterns in a user’s stress signature across days, weeks, and even seasonal cycles. By spotting recurring rhythms and deviations, we will be able to anticipate stress spikes before they occur.

This kind of temporal intelligence moves stress support from reactive to proactive. It’s similar to how predictive maintenance works in manufacturing or how glucose monitoring informs diabetes care, catching the signal early, and you can act before damage is done.

“Our models won’t just respond to spikes, they will learn from patterns: what typically happens before a drop in resilience or a sharp rise in burnout indicators. That’s where the real value is: in preventing a stress crisis, not just reacting to one.”
Dylan Curley, AI/ML Engineer at Google DeepMind and Advisor to WONE

By learning each individual’s unique stress rhythms, the recommendation engine becomes more informed, more accurate, and ultimately, more helpful.

Personalised Recommendation Engine

Personalisation isn’t just a feature, it’s the foundation. Enormous care goes into ensuring our AI model captures personal nuances so that the model can make highly individualised recommendations tailored precisely to each employee's needs.

These tailored suggestions lead to higher engagement and better long-term habit formation. In the near future, the recommendation engine will read each user’s data in context, factoring in their environment, routines, past engagement, and WONE Index responses.

Every suggestion will be powered by contextual AI that values relevance over quantity. Instead of overwhelming users with options, it delivers one right thing, at the right moment.

“The future of health tech isn't about overwhelming people with options, it's about guiding them to the most effective action for their unique context and needs, exactly when it matters.”
Yojan Patel, Health AI Researcher at Google and Scientific Advisor at WONE

Interventions That Fit Your Life

Even the best insight is meaningless if it doesn’t fit into someone’s day. That’s why WONE’s interventions are designed to be short, specific, and flexible - we call them ‘micro moments of recovery’.

We draw on the research behind just-in-time adaptive interventions (JITAIs), a proven behavioural science model used in everything from smoking cessation to anxiety management. The principle is simple: when the action is delivered at the moment of need, and it feels achievable, the likelihood of change increases.

That’s exactly what the future holds at WONE. A nudge before a tense meeting. A reset after poor sleep. A gentle redirect before a thought spiral. These aren’t generic wellness tips, they’re precise interventions delivered when they’re most useful.

Human-Centered Design for Trust

Health tools only work when people trust them. And trust is built on transparency, safety, and empathy.

From day one, WONE has been built with privacy-by-design principles. Every insight comes with a clear explanation. Our tone is informed, not clinical, expert-led, but warm. We don’t expect people to blindly follow recommendations. We help them understand where the insight comes from and why it matters.

This meant developing a custom prompt architecture to enforce tone and boundaries, embedding structured metadata into the model’s inputs, and applying safety guardrails to prevent hallucinations or inappropriate advice. It also meant testing the LLM against real-world use cases, measuring both safety and user engagement.

The result is a first-of-its-kind coaching engine designed to integrate live data, user history, and real-time behaviour into a guided conversation. The Coach will continue to evolve, learning not just what helps people manage stress, but how they experience it.

The Future of Stress Is Adaptive

The science is clear: unmanaged stress drives down performance, increases health costs, and erodes resilience. But we now have the tools to address stress in a new way, using AI not just to track symptoms, but to understand their root causes and respond intelligently.

At WONE, we believe this is where health at work is headed. It’s not about pushing more content. It’s about knowing what matters, when it matters, and making it easy to act.

We’re not trying to replace human care. We’re making it easier to reach. Easier to personalise. Easier to trust.

Because when we get stress right, we don’t just avoid burnout. We unlock the conditions for better health, better focus, and better lives.
