Our Story

Hi, I’m Danielle Fujii, creator and CEO of zDen. I created zDen because I needed a better way to rest and recover during migraine attacks.

I learned quickly that darkness mattered, but the options I had didn’t solve the whole problem. Blackout curtains helped with outside light, but not the light inside the room. Sleep masks were uncomfortable for me. I wanted a simple way to create a dark, private sleep space whenever I needed it.

That personal need became zDen.

What I didn’t expect was how many other people needed darkness for completely different reasons. People began using zDen for shift work, shared rooms, dorms, travel, CPAP comfort, sensory sensitivities, naptime, migraine recovery, and busy homes where one person needs sleep while the world around them is still awake.

Along the way, I learned something that continues to guide zDen today: sleeping doesn’t always mean sleeping well. Light and distractions in our sleep environment can affect the quality of the sleep we get, even when we think we’re sleeping just fine.

That’s why I care so deeply about the details. Sleep is personal. When you’re tired, recovering, adjusting to a different schedule, or trying to sleep in a space you can’t fully control, quality sleep can feel out of reach.

My goal is simple: to make quality sleep more accessible to everyone. That commitment goes beyond creating zDen. Through our Sleep Access Program, we’re working to help bring better sleep environments to people and communities who may not otherwise have access to them.

Because everyone deserves the opportunity to sleep well.

Here’s to better sleep, anytime, anywhere.
