Zero-knowledge business software

Your data stays yours.
Sealed against breach and insider access.

We build business software on one rule: the people who run the servers can never read what is on them. Not hackers. Not administrators. Not even us.

No master key

The claim

Steal our servers, and you have stolen nothing.

01 · breach

A stolen database is ciphertext

There is no master key on any server. Nothing to unlock, nothing to ransom, nothing to sell.

02 · leak

Nothing readable can spill

Nothing readable exists on the server. Not in a misconfigured bucket, a dump, or a careless export.

03 · insiders

No job title opens a record

No administrator, no DBA, no vendor, not even Zeromatics. Access comes from keys you control.

Two databases are stolen. Only one makes the news.

Same breach. Same attacker. Same dump. Different day entirely. And there is no key to steal.
How it works

It locks before it leaves.

01You enter it. Readable on your screen — and nowhere else.£40,000
02It locks. Encrypted on your device. The key is derived from your password and never travels.a71e·d40b

Even we can't open it.

Why it matters

The headlines that shouldn't exist.

April 2026. Two countries, one month, one failure: the data sat readable on a server.

LAND · COURTS · TRANSPORT April 2026 · UAE

Dubai's land registry, courts and transport authority breached in one campaign

A hostile group claimed an attack on the Dubai Land Department, Dubai Courts and the Roads and Transport Authority — around 149 terabytes reportedly exfiltrated, with claims of petabytes more destroyed. Property records, case files and citizen movement data: the administrative backbone of a city, taken from its servers.

With Zeromatics: 149 terabytes of exfiltrated ciphertext is 149 terabytes of nothing.

NATIONAL IDENTITY April 2026 · France

19 million citizens' ID records offered for sale

France's agency for passports, national IDs and driving licences confirmed a breach. Names, dates of birth, addresses and account data of up to a third of the population — up for sale on criminal forums within a day. The flaw behind it was so basic the attacker called it 'really stupid'.

With Zeromatics: the same flaw would have served the attacker 19 million sealed records — and no keys.

Boring, audited cryptography.

No invented ciphers. The same primitives that protect Signal — applied to business software.
