Products

Five product lines. One engineering team.

We focus on five kinds of battery-powered or always-on devices that capture voice, location or sensor data. Each has its own architecture, certification path and failure modes. Pick the one closest to your product.

The five categories at a glance

Certification effort is the biggest difference between them. It shapes your schedule more than any other single factor.

Fit

What we do not build

Saying no early saves you a sales cycle. These are outside our scope.

  • Products directed at children under 13, including AI toys
  • Government, defense and FirstNet devices
  • Commodity devices where the lowest unit price is the only goal; an off-the-shelf product will serve you better
  • Mobile apps and cloud backends as standalone projects, with no device in scope

Questions about our solutions

Our device does not fit neatly into one category. Can you still help?

Yes. Many products combine categories, for example a voice badge with LTE and GNSS, or a senior watch with a voice assistant. Pick the closest one on the form and describe the rest. The architecture and certification path are worked out at Gate 0.

Do you build products for children?

No. We do not build products directed at children under 13, including AI toys. Our companion devices are for users aged 13 and older, with a focus on adults and older adults.

Do you build the mobile app and cloud backend too?

Yes, as an option. By default we deliver the device firmware, the device-side protocol and an SDK, and test against your backend. If you want us to build the companion app and backend as well, we deploy them in your own cloud account, so you hold the keys and the data.

Are there projects you turn down?

Yes: children's products, government and defense work, and FirstNet devices. We also tell you when an off-the-shelf device would serve you better than a custom one.
