Safe Route

The Cyclist

Everyday Sara commutes from home to work using her bike. Weather conditions can be harsh in Brussels and wind conditions dangerous.

CLARA shows me exactly which streets are shielded from the wind. I can ride home safely!

Smarter Real Estate Investments

The Home Buyer

CLARA uncovers invisible air quality and microclimate risks, giving you a clear picture of a property's true long-term value.

The agent said it was a great location. I checked CLARA and saw the balcony sits right in a pollution hotspot. We saved ourselves from a bad investment.

Operational Efficiency and Safety

The Restaurant Manager

Adam uses CLARA to optimize staffing levels and stay ahead of weather risks, ensuring a safe and comfortable experience on the terrace.

If the app predicts high wind on our street at 19:00, I cancel the extra waiters. I also get alerts to close the parasols before a gust hits. It saves me money and protects my clients.

Healthy Living

The School

In her classroom, everyday Olivia used to guess when to open the windows. With CLARA, she can see exactly when the air outside is clean.

I ventilate at the right moment and keep my pupils safe from traffic pollution.
