33signals signal over noise
Evidence Take the Signal Check
Behavioural intelligence for real work

Untangle your people from the work spiral.

Most software makes humans work for it — feeding forms, chasing updates, drowning in meeting summaries. We reverse it. The work updates the system through you, the friction falls away, and the signal finally stands out from the noise.show the working

Free. Three minutes. You'll leave knowing something true about your business — no deck, no call required.

The gap nobody talks about

Everyone has the tools. Almost no one has the value.show the working

88%
of businesses now use AI in at least one part of the business.
~6%
actually capture meaningful value from it.
~21%
have redesigned the work around it — the one change that drives the value.

Adoption is table stakes. The difference between the 88% and the 6% was never the tools — it's whether the work was rewired around them. Untangling that work is the only thing we do.

The next evolution

It's not software. It's work systems.

Work keeps reinventing itself. Every leap added power — and quietly added friction.

Work systems
The software updates itself from your work.

Here's the losing trade every tool makes you take: you pay to feed it through forms and dropdowns, and what comes back is always a degraded, context-stripped version of what you already knew — so you book another meeting to recover it. We end that trade. The work updates the system as a by-product, and the insight comes back richer, not thinner.

How humans actually work

We build for behaviour, not against it.show the working

Every tool that fails fails the same way: it assumes people will do extra work to keep it fed. They won't. So we started from how people actually behave, and built backwards from there.

01

People won't log into tools. They will answer an email. So updates happen through email and voice — not forms.

02

Friction kills data quality. Every dropdown is a reason not to update. Remove the dropdown.

03

Conversation is richer. People say more, and give more context, out loud than they'll ever type into a form. The room is your richest data.

04

The hardest part of any task is starting it. We engineer the start to cost almost nothing.

Before / after

What changes the moment the friction is gone.

Life without us

The spiral.

  • Five logins to update five systems, so nobody does.
  • Meeting summaries pile up faster than anyone can read them.
  • The CRM rots, because keeping it current is a second job.
  • Work dies in the dead space between meetings.
  • You ask AI what to do next — from scratch — after every call.
Life with us

The untangle.

  • Answer an email and the system updates itself.
  • Meetings arrive as an inbox that tells you what matters.
  • The record fills itself from the work you already do.
  • The meeting never ends — work moves between sessions.
  • One place that remembers everything and nudges the gaps.
Where the work goes to die

Half your week is meetings. Most of it evaporates.show the working

The average team spends around 11 hours a week in meetings, and only about 1 in 10 of those are rated highly productive by the people in them. The rest leaks away — in summaries no one can keep up with, in decisions that fade by the next call, in the dead space between sessions where the real work quietly stops moving.

We don't give you another summary. We give you the next person in the room.show the working

One that remembers every commitment, chases the gaps by email so no one has to log in, and keeps the work moving between meetings. AI does the draft. Your people close the loop. That single shift is the difference between a record of what was said and a system that gets it done.

The future of work

AI didn't fix the overload. It moved it.show the working

We used to drown in emails. Now we drown in meeting summaries, and run back to AI after every call just to remember what we owe. More intelligence, more noise. The future isn't another tool that needs feeding. It's software that updates itself with humans in the loop — where the work creates the system as a by-product of getting done, and every insight compounds the next. We've studied how people behave around work for twenty years. That's what we build for.

See it for yourself
Most advisers bill you for months before they tell you anything true. We do it in three minutes.show the working

The Signal Check reads your business the way we once read a billion-euro portfolio — for the signals underneath the noise. Twelve questions. You'll see what's working, where your work is leaking, how you compare to your peers, and what it's quietly costing you. Advisory-grade insight, before you've even spoken to us.
