We are Dennis and Martijn, and we are the founders of Polarwise.

We embarked on this journey to fix what others wouldn’t: create products dedicated to sweat protection that actually work. Martijn’s years of dealing with excessive sweating and Dennis’s frustration with the industry’s flashy but ineffective products pushed us to rethink what was possible.

Working closely with dermatologists, we created a product that keeps you dry for 7 days, lasts for months, and delivers confidence that lasts. Proudly made in Amsterdam, we keep on working to lead the future of sweat protection with real solutions that make a difference.

The Polarwise journey

February 2019

“What if?” The light bulb moment

What if there was a better way? That question sparked an idea we couldn’t ignore. To validate it, we joined a start-up weekend in Delft, pitched our concept, and gathered feedback. We learned that, like Martijn, many struggled with sweating but felt too embarassed to talk about it. Motivated by this, we partnered with a pharmaceutical company to create a solution that actually worked, combining their expertise with our determination to make a real difference and break the stigma around sweat.

The launch

We launched our first product - a sweat solution for armpits initially designed for men - in the Netherlands. Money was tight, but that didn’t stop us. We handled everything ourselves, from filling bottles and hand-labeling every product to managing shipments and customer service. Soon, messages from women poured in, sharing that they faced the same issue. Realising the need to make our product inclusive, we got to work and quickly developed a unisex formula that could help everyone feel confident and in control.

Our first expansion

After success in the Netherlands, we expanded to Belgium. From there, things took off, and we were soon helping more people across France, Germany, Austria, and Switzerland.

Taking over Europe

With growing trust in our product, we entered the United Kingdom and the rest of Europe. The Polarwise community continued to grow, and every piece of feedback drove us to make our solutions even better.

Beyond armpits

Our community spoke, and we listened. With insights from thousands of customers, we expanded our range to address sweat beyond armpits. From hands to feet to face, Polarwise became a solution for all areas of the body.
