Software solutions for everyday work

Software solutions
for everyday work

We start with how work really happens, then build software for what slows people down. AI agents get a seat only where they help.

What we do

Your work first.
Then the software.

A lot of working time goes into chasing information and keeping documents in step. That is our starting point, and we are still testing it. TreZeroQuattro builds software solutions for those parts of everyday work.

  • Map the work first

    Before deciding what to build, we look at the work.

  • Plain rules, then AI

    Rules that can be written down stay rules. AI handles the reading and drafting.

  • People keep the last word

    In our demo, nothing goes out until a person approves it.

Watch an agent work

An email asks for 20 stewards. The agent prepares everything. You approve.

With ATS

We build alongside
a real company

ATS (Around The Show) has worked in security and ticketing for live events since 2000. Right now we are mapping how live events run, before deciding what to build. It is a slow start, on purpose.

  1. Start with one company

    Today that means ATS.

  2. Ship small things often

    That is our aim, so a wrong guess stays small.

  3. Learn from real use

    We want to see how people actually use it, then fix what does not work.
