About

A home should be looked after.

Vahti exists because peace of mind shouldn't cost your privacy. We make a small sensor that notices the things you can't — smoke, damp, noise, cold — and tells you calmly, in plain language, without ever recording a thing.

Vahti

/ˈʋɑh.ti/ · noun · Finnish

Meaning

A watchman; one who keeps guard so that others can rest.

Where it began

Named after the quietest job in the world.

In Finnish, a vahti is the person who stays awake so everyone else doesn't have to — the night watchman who walks the halls, checks the doors, and says nothing unless something is wrong. Good watching, it turns out, is mostly silence. That felt like exactly what a home sensor should be.

So we built one. A small device that pays attention to the air, the temperature, the sound levels — the physics of a home, never the people in it. It doesn't listen to words or look at faces, because a good vahti doesn't need to. It just keeps watch, and when everything is fine, it lets you rest.

What we believe

Three rules we don't break.

Privacy is the product

No audio. No video. Ever. Our sensors measure levels — decibels, particles, degrees — never words, faces, or identities. There is nothing to leak because nothing is recorded.

Calm over noise

Alerts explain what happened in plain language — never a wall of beeps or a panic in the middle of the night. If everything's fine, we say so, and then we stay quiet.

Small enough to forget

One device that plugs into any outlet and disappears into the room. Five minutes to set up, then years of quietly doing its job — no hubs, no wiring, no fuss.

Our promise, in one line.

If a feature would ever require listening to you, filming you, or selling what we know about your home — we won't build it. We look after your home, not your life.

No audio. No video. Ever.
