Building the operating system for safety and security

Building the operating
system for safety and
security companies

One platform for the whole job, from the first request to the final account, so there is more time to grow.

Your work first.
Then the software.

We think much of the time in safety and security work
goes into managing the job, proving it was done and
keeping records up to date. We are still checking that with ATS. TreZeroQuattro is building software to give that time back.

  • 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.

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

We map the work
with a real company

We design the software around the everyday work of an event security company.

ATS (Around The Show)

Has done event security and ticketing since 2000. It is our discovery partner, and its founder and CEO, Fabio Marsili, is Mattia's father.

Our discovery partner

We are mapping its jobs from the first request to the final account, slowly, on purpose.
