# Helder: beat brain fog when it hits

> Helder is a band that cools your forehead in short pulses and brings your focus back while you keep working. Launching in 2027. Join the waitlist at https://gohelder.com/.

Helder is Dutch for *clear*. We're building it for the part of the day when your head isn't.

## Why we built this

Most days there's a moment where your head gets foggy. You keep working, but everything takes more effort.

"Most days my head got foggy, and cold seemed to help. So I started building something that does it properly." — Sjoerd Memelink, founder of Helder

It started with ice packs. Now the device is being tested at San José State University.
