Principles are how a small team stays coherent across disagreements. We publish ours so collaborators know what they are signing up for — and so we can be held to them when we slip.
- 01
Optics is the integration constraint.
Every other design decision — model size, system topology, industrial form — bends to the physics of light. We start every architecture review at the light path.
- 02
On-device by default.
The wearer's gaze, their voice, the room they are in — none of it leaves the device unless leaving the device is the user's choice. Latency, resilience, and privacy all point the same direction.
- 03
The wearer is the protagonist.
The device serves attention; it never competes for it. Interfaces materialize on demand and dissolve when no longer needed. If a feature requires the wearer to disengage from the room, we reconsider the feature.
- 04
Intent is the primitive.
Not apps. Not windows. Not files. The unit our system reasons over is what the wearer is trying to do. App-shaped thinking is a translation layer we are deliberately removing.
- 05
Specs before prototypes.
We write the contract a product must satisfy before we draw the product. FOV, weight, latency, power, battery life — set in a document, defended in review, then committed to silicon.
- 06
Friction is a signal.
When the user struggles, there is a missing optical, AI, or system primitive. We treat every friction point as an architectural request, not a UX bug.
- 07
Pilots before launches.
We earn the right to ship a consumer product by surviving real industrial use. The first wearer is a domain expert in a high-stakes context, not a curious early adopter.
- 08
Publish what we don't know.
Open uncertainty separates collaborators from spectators. We list our open questions in writing — and we update the list as the technology answers them.
- 09
Smaller than the vision, on purpose.
The first product is a slice of the long-term ambition. We protect the long horizon by being honest about the short one.
- 10
Engineering is the storytelling.
Diagrams, papers, working prototypes. Demos that actually run. We do not narrate the company through slogans; the artifacts are the argument.
