Who validates
the future?

In complex B2B sectors, early-stage sales pipelines are routinely filled with optimism rather than intent. Investors scrutinise spreadsheets, yet these frequently obscure the genuine commercial reality of the companies they are evaluating.

For CEOs and founders, if your commercial engine is broken we give you the same independent read: what is working, what is at risk, and what to fix first.

Our mission is to bridge this critical information gap, providing a rigorous, forward-looking assessment of the one question that determines your return.

The risk: investing based on a £20M forecast that is actually £5M in reality.

Our mandate: tell you if the £20M is real, inflated, or fiction.

The risk: hiring, spending and raising against a forecast that only exists in the deck.

Our mandate: separate the story you tell from the one the evidence supports.

Whatever the decision,
the question is the same.

Investors, operators and acquirers come to us at different moments. The commercial question underneath is always the same: is the revenue story real? Each engagement is built around the decision in front of you.

Find out what is real.
Then fix it.

Our core work is commercial due diligence: an independent test of whether the commercial engine behind a revenue number will deliver it. When clients want help acting on what we find, we stay for the fix.

Four decades of execution.
Zero consultant speak.

Financial diligence examines historical performance. Legal diligence identifies regulatory exposure. Neither interrogates the single question that determines your return: can this company actually deliver the revenue it projects?

We are not career consultants. We are seasoned commercial leaders who have carried quotas, built high-performing global teams, and executed successful exits.

SLAM fills the gap between spreadsheet analysis and commercial reality, assessing execution capability, not just financial history.

Traditional advisors look in the rear-view mirror. SLAM is the navigation system.
Anders Mogensen & Stephan Lahn, Founding Partners

Two lenses.
One verdict.

Two operators, four decades of building, fixing, and stress-testing commercial engines. We know what works because we have done it ourselves. We know what fails because we have fixed it for others.
