When to Take What @health.tech global summit Basel

We are thrilled to be a part of this years health.tech in Basel.From the 3rd to the 5th march we will participate at the fair, in various panels and even pitch.

When to Take What is your AI-powered health companion: Turning daily signals into better health decisions.


Most health decisions fail not because people don’t care –
but because guidance is fragmented, generic, and disconnected from real life.

What do we do?

We are building a holistic health system for people who are technically “healthy” – but don’t feel well.

We focus on the large and overlooked group living in a liminal health state:
not sick enough to be treated, but not healthy enough to thrive.

Instead of chasing quick fixes, WTTW helps people understand how sleep, nutrition, habits, timing, and personal context interact over time, and turns that complexity into clarity.

How it works.

Tell us your goals

Share your health goals, what you’re taking, any conditions, even blood work if you have it. An AI companion turns it all into a dynamic profile that evolves with you.

Your adaptive plan

You get a supplement and lifestyle plan tailored to your body, habits, and goals. As your profile evolves with you, your tailored plan also adapts as new data comes in, so it always stays relevant and effective.

Track, improve, repeat

From daily reminders and progress visualizations to expert nudges and community streaks, WttW keeps you motivated. You see what’s working, adjust where needed, and build habits that truly last.

Our features do more than just tracking.

A personal health twin that learns with you.

Edgar, your AI health assistant

No one-size-fits-all chatbot, but a trained AI specialist. Edgar understands your patterns, nudges you at the right moments, and grows with you to help healthy routines take root.

Adaptive Supplement Plans

No generic advice: our AI designs supplement and lifestyle routines that evolve as your needs, data, and goals change.

Habit support that works with you

Streaks, progress insights, and timely nudges, designed to keep you going, not wear you out. Not through pressure, but through understanding what works best for you.

Clarity you can trust

Evidence-based insights, explained clearly, so you understand what you’re taking, why it matters, and what’s right for your body.

Experts When You Need Them

Access to doctors and nutritionists, real people to guide you when you need it, not just when things go wrong.

Only the good stuff

Smart reminders when you’re running low. Easy access to supplements we’ve verified – nothing extra, nothing shady.

Watch how we build the future of health.
