Helder is Dutch for clear. We’re building it for the part of the day when your head isn’t.
The afternoon dip
You know the feeling. Mid-afternoon, focus slips, energy drops, and another coffee barely makes a dent.

Why I’m building Helder
“Every afternoon around three, my focus just disappeared. Coffee stopped helping, so I started building something that would.”
What began as a side project is now in early testing at San José State University.
