The most important hour of your quarter is in no one's calendar.

A Private Briefing is a closed thinking room for one real decision at the top. No talk, no slides, no audience — a futurist, your question, off the record. Afterwards a written memo: your options, the risks and a clear recommendation, in black and white.

When a Private Briefing matters.

  1. You make decisions no one inside honestly pushes back on — because everyone is on your payroll.

  2. Your organisation debates the future in committees — but no one translates those trends into the one decision now in front of you.

  3. You don't need another workshop. You need three hours with someone who understands the disruption — and the business.

  4. What is discussed must not leave the room. Confidentiality here isn't a clause — it's the format.

Three routes, one principle: clarity for the one decision.

All prices net, plus VAT. Payment via Stripe, confidential scheduling after payment. Travel within the DACH region is included in the on-site format. Every briefing closes with a written memo within 72 hours: options, risks, recommendation.

Why a briefing moves more than a workshop.

Three findings from research and practice — and what they mean concretely for your next decision.

Thinking ahead pays off — in hard numbers.

Companies that build the future into their decisions earn more and grow faster than the average, year after year. Rohrbeck and Kum proved it across seven years: +33% profitability, +200% growth.

From practice: A supplier wants to know, two years before everyone else, what the shift in drivetrains means for its core business. A briefing turns vague worry into an investment decision with a clear time window — before competitors even react.

Rohrbeck & Etingue Kum, Technological Forecasting & Social Change 129 (2018)

Your most expensive hour is the one you waste.

Executives spend around 40% of their time on decisions — and consider most of it wasted. Only one organisation in five rates itself genuinely good at deciding.

From practice: Instead of sending the plant-relocation question through the advisory board a fourth time, a managing director settles it in three focused hours — with someone who pushes back, and a memo she can stand behind.

McKinsey & Company, "Decision making in the age of urgency" (2019)

The outside view prevents expensive blind spots.

Even professionals judge the same situation surprisingly differently — this invisible scatter, "noise", costs organisations dearly. An independent outside view irons it out.

From practice: Before an eight-million acquisition, an owner deliberately brings in someone neither on the payroll nor paid on the deal — and spots the one risk everyone inside had missed.

Frequently asked.

How is a Private Briefing different from classic consulting?

No project, no method inventory, no slide deck. A focused, confidential session on exactly one decision — with a written memo instead of follow-on engagements.

Who takes part?

You alone, or a closest circle of up to ten people from one organisation. On-site at your location or via Teams.

What do I get in writing?

Within 72 hours, a memo with your options, the key risks and a clear recommendation — documented to stand behind your decision.

How confidential is it?

Without exception. Nothing leaves the room; with an NDA on request. Scheduling is handled discreetly after payment.

What does it cost?

On-site €8,500, remote €5,500, retainer €34,000/year (five briefings for the price of four). All prices net, plus VAT.
