Shorts · That Spreadsheet

Take the risk out of the spreadsheet that runs the business.

Thirty seconds on the sheet nobody dares touch, and what we do about it.

What the short says

  1. This is the spreadsheet that runs the business. Nobody dares touch it.
  2. Dozens of tabs, three versions, and one person who understands it.
  3. When they go on holiday, everything waits.
  4. We find what the sheet really does, and what it is holding up.
  5. The AI takes the copying and the checking between tabs.
  6. Bob still signs off the numbers that matter.
  7. We are Subversive. Taking the risk out of critical business systems.

The problem

What goes wrong

One spreadsheet holds the prices, the stock or the rota, across dozens of tabs and three versions. One person understands it. When they are away the work waits, and a slip in one cell can travel a long way before anyone sees it.

What we do

How we fix it

We find what the sheet really does and what it is holding up. AI takes the copying and the checking between tabs. A person you name still signs off the numbers that matter.

What you get

  • What the sheet does, written down

    Every tab, what feeds it and what it feeds.

  • The copying handed over

    AI moves the figures between tabs, so nobody retypes them.

  • Checks between tabs

    Numbers that disagree are flagged before they travel.

  • A human sign-off

    The figures that matter still go past someone you name.

How we start

Start with a day.

A workshop or a discovery day, and you keep the written notes whatever you decide next.

Then a first piece of work. Or keep us on: three months to begin, then month by month.

We quote for the job, once we know what it is.

A larger organisation? Start here.

On your own? Your first hour is free.
