About us

It started as a tool for me. It ended up being for everyone.

Anuxis didn’t come out of a business plan or a market study. It came out of a phone call from a hospital, weeks of uncertainty and a question that kept me awake at night.

The story

A few years ago my father fell ill with severe meningitis. He spent days in a coma. When they finally brought him round, he spent weeks in a fog, unable to manage anything. It took him months to recover fully.

One night, in the middle of all that, I woke with a start, thinking: if something like that happened to me, I’d leave my business partners in a terrible position. There’s information I handle that’s best handled by me alone. Passwords, logins, contracts, instructions. Things it makes no sense to share day to day, but which are essential in an emergency.

Things it makes no sense to share day to day, but which are essential in an emergency.

Being a developer, the first thing I did was build the tool myself. Something simple and functional, for my own use. But the more I used it, the clearer it became that the problem wasn’t just mine. Anyone with responsibilities, with a family, with an even slightly complex digital life, sooner or later faces the same question.

So what began as a personal project grew into Anuxis: a SaaS that lets everyone have their own safety net.

You don’t have to die for the information you handle to be urgently needed by others. An accident, a hospital stay, a trip that goes wrong. That’s what Anuxis became: the answer to a question nobody has sorted out.

What sets us apart

What makes Anuxis different

Useful today, not just on the day something happens

Your important papers, easy to find and to hand from anywhere. Delivery is the safety net behind it.

Your trusted contact can ask for it, and it arrives within hours

No certificate or power of attorney needed: they ask, we alert you, and if you say nothing, they receive it after the period you chose.

Forgotten your password? You can recover it

It’s designed for people who don’t want to be their own IT department: no 24-word recovery phrases, no papers to print out and keep safe.

You know who’s behind it

A Spanish company with a name and an address, which invoices you with VAT, keeps your data in the European Union and is contractually bound to give you a year’s notice if it ever closes.

What we believe

Five non-negotiable principles

Simple before complete

Every Anuxis screen has to pass one test: would a seventy-year-old use it on their own, without help? If not, it gets simplified. Because a half-prepared folder reaches nobody on the day it’s needed.

Calm, not fear

We’re not going to frighten you into signing up. We talk about having your affairs in order, like taking out home insurance: because it’s the sensible thing to do, not because something is going to happen.

Saying what we can and can’t do

That we manage the keys, what we see and what we don’t, what would happen if we closed. We’d rather lose a sale than win it with a word that doesn’t hold up.

What’s yours is yours

We don’t sell your data or your trusted contacts’ data, we don’t use it for advertising and we don’t train any artificial intelligence on it. You can download your files whenever you like.

Still being here in ten years’ time

A service like this only makes sense if it lasts. That’s why we charge a fair price from day one instead of giving it away, and why we’ve put in writing what would happen if one day we couldn’t carry on.
