Explore NekoCurrencyWe build things we'd want to use.
Software should feel warm, calm and personal — and what you put into it should always belong to you. We start small, ship carefully, and grow with the people who trust us. No ads, ever.
The company
An independent studio, run by two people who love cats.
NekoSense AI is the app studio of J&W Neko Ventures LLC — a small, independent company building for people who care about the details.
We believe the apps you use every day should feel warm, calm and personal — and that what you put into them should always belong to you. Alongside the apps, we run Nyangi Studio USA, a small retail line for black-cat lovers.
