Applied AI Research Lab · Sweden

We study how AI agents behave with people, and put them to work.

An agent’s code decides what it can do. The people around it decide whether it works: who relies on it, who checks it, and who tries to steer it. We research that side, and we deploy agents in process-heavy businesses such as accounting and logistics firms, with the gain proved against sites that have not started yet.

What we do

Three ways we work. Each one can end in a no.

01 Deploy

Agents on one process, in three stages.

MeasureSix weeks to find where the time goes in one process. You keep the baseline whatever happens next.
ProveTwelve weeks. Agents go live in waves drawn by lot, and the sites still waiting are the comparison.
RunWe operate the agents in production, per site, for as long as they earn their keep.

Start with one process, or several at once. Scope and price follow the deployment.

How Deploy works →

02 Secure

Every agent is a new way in.

An invoice with one hidden line can read as an instruction, and an agent that takes it as an order pays the wrong account. We test agents the way an attacker would, before they go live: AI security reviews and agent red-teaming, with a specialist offensive-security partner.

03 Transform

The whole business, not one process.

For an owner who has decided to change the business: the same three stages, applied process by process, with the margin as the measure.

How Prove works

Measured, not asserted.

Sites go live in waves, with the order drawn by lot and the decision rule written down before the first wave. The sites still waiting are the comparison, so the gain is measured against them rather than against a forecast.

If the measured gain does not clear the rule, the work stops there. You keep the baseline and the comparison.

Research

Three research lines, one question: what happens between AI agents and people.

We take that question where it is hardest to answer and most costly to get wrong.

Line 1

How agents perform in real work

Our first Report concluded that the binding constraints on enterprise AI are organizational rather than algorithmic. The Agentic Enterprise tests that, with its kill criteria written down first.

Line 2

AI and mental-health safety

A chatbot answering someone in psychosis is one of the hardest tests of how an AI system behaves with a person, and a psychiatrist can judge what a safe answer is.

Line 3

AI-assisted evidence synthesis

Whether AI-assisted review of medical evidence holds up when people make every judgment that carries weight.

From the next Report on, every 900 Report is preregistered, independently verified and published with its error rate.

Two kinds of data, kept apart

Research data

From our studies, including those with patients, under academic and ethical governance. It never feeds our products.

Deployment data

From the agents we run, under each client’s contract. It improves our agents, and it is never sold.

900 Note 0019 August 2026About two hours of work

Nearly half of executives pulled back on AI agents. Half of what?

Two figures traveling as a single sentence turn out to come from two different surveys, of two different populations, with revenue thresholds an order of magnitude apart.

Where we are

What exists today.

A firm that intends to publish its error rate should be able to say plainly what it has built.

  • 01A written method and operating standard.
  • 02One Report and one Note published.
  • 03The Agentic Readiness Diagnostic, built and audited against sixteen adversarial cases. Independent certification is next.
  • 04Nine open-source repositories, public.
  • 05Five named people, and what each has done.

One thing to know

Our published Report predates the current method. It was not preregistered and it carries no error rate. The next one will carry both.

Start with one process.

Write to us with the process that eats the most time. The first call contains our qualification questions rather than a pitch, and if the process is not worth measuring, we say so.

Or run the free diagnostic on one workflow. The diagnostic opens after independent certification. Tell me when it opens.
