What we believe
Four principles, no buzzwords
Devices instead of servers
What can run on your device should run on your device. That's faster, cheaper and more private.
Ownership instead of rent
Units instead of a subscription, clear quotes instead of lock-in. You should stay because it's good — not because the contract runs.
Honest technology
We only promise what demonstrably works — and we'll tell you when something isn't (yet) sensible.
Personally reachable
You talk to the person who builds the software. No hold queue, no ticket system.
