Our Manifesto

Technology should serve you, not replace you.
Big Tech builds for profit, not with soul.
We take a different path.
We build products with a core focus on you, the end user.
Designed to give you back your time and attention to what matters most.
Our tech feels natural to use, helping you focus and move forward with intention.
Because we believe in the limitless.
That your goals are within reach, and the right tools can help achieve them.
The magic isn't just in our products.
It's what you can do with them.

From Rehearsals to Real Users

Rehearsals

I spent 11 years as a violinist fighting the same problem in every practice room and symphony hall: the metronome.

Tony Kim, Founder and CEO of Walnut, presenting MetroBand Pro at the IEEE International Conference on Neural Engineering.

Research

This led me to develop MetroBand Pro, the world's first wearable metronome headband. Debuted at the IEEE International Conference on Neural Engineering.

Real Users

Now we're bringing MetroBand to musicians and students nationwide. MetroBand launches on Kickstarter. The MetroBand Pro waitlist is now open.

Where humanities and technology intersect.

We design at the crossroads of technology, the liberal arts, and neuroscience.

Every interface we create begins with how it feels to use, not just how it works.

Our products are built to awaken your innate sense of curiosity, creativity, and collaboration.

Born in a garage.

Amazon, Apple, and Google started in garages. So did we.

Early MetroBand Pro prototype with exposed wiring and taped electronic components during initial development

Our first prototype of MetroBand Pro was bootstrapped from day one.

Every component was engineered, tested, and refined in-house through relentless experimentation.

Unlike the companies above, we're fully committed to American manufacturing.
