From Signal to Architecture: Europe’s CEO Open Letter Deserves an Architectural Answer

From fragmented to a structured Ecosystem

The fifth and concluding post in a series responding to the seven CEO open letter | Paul Hobcraft | May 2026a ten minute read


On 5 May, seven European CEOs published an open letter in eight countries simultaneously. It was an act of genuine collective will — and a signal that a threshold of discomfort had been crossed at the highest levels of European industrial leadership.

I have spent four posts since then working through what that signal actually means, what it doesn’t yet say, and what a structurally honest response requires. This fifth post is both the conclusion of that series and the opening of a different conversation.

A senior European institutional figure observed publicly last week that the CEO letter is a call to action — and crucially, a call to action also for the signatories themselves. That observation goes to the heart of what this series has been building toward. It deserves to be developed fully.

So, this is the concluding post on what is needed in clear response to this open letter.

You Named It. Now Own It.

Europe needs interconnected Ecosystems

A direct response to the seven European CEOs who wrote an open letter, with the EU Directorate in mind — and also to every large-company leader in Europe watching this unfold.

By Paul Hobcraft  |  Creator, IIBE Framework  |  Ecosystems4Innovating  |  May 2026

This week, seven of Europe’s most significant technology CEOs did something genuinely rare.

Christophe Fouquet, Guillaume Faury, Börje Ekholm, Arthur Mensch, Justin Hotard, Christian Klein, and Roland Busch agreed on a single text, signed it together, and pushed it into national newspapers across eight countries. These CEO’s represent ASML, Airbus, Ericsson, Mistral AI, Nokia, SAP, and Siemens.

€417 billion in revenues.

€1.1 trillion in market capitalisation.

957,000 high-tech jobs.

€40 billion in annual R&D.

213,000 patents.

That is not a symbolic gesture. That is sovereign-scale industrial weight applied to a public argument.

And the argument is correct: Europe keeps inventing what others end up scaling. Fragmented markets. Overlapping rules. A regulatory reflex that governs rather than builds. A capital union still on paper.

I respect the letter. I respect what it took to produce it.

But I want to say something directly to those seven leaders — and to every CEO of a large European company reading this:

You named it. That means you now own it.

Siemens and the Dual-Force Model Is a great case study for building Ecosystems

Positioning the Dual-Force built with AI and IIBE within Siemens

Siemens are a great case study in validation about the need to apply a Dual-Force Model to building Ecosystems , yet also there are certain levels of caution in their next steps

This is a week (April 20th-24th) so critically important to Siemens and the Industrial Sector. This is the coming week for HANNOVER MESSE, the most important international platform and hot spot for industrial transformation

Siemens commits significant resources and budgets to this event this takes you to their navigation page to sign up and join in. It offers a “flagship” of their business. I gain enormous understanding of what is “internally” going in or in “selected” collaborations within the organization, in products, services, ideas and their approach to their markets.

They offer an immersive experience before, during and after the HM 2026 with their interactive Booth Navigator and a non-stop Stage Program where you can create your own experience and explore a daily stage program over five days packed with tech trends, industry insights and success stories.  You can watch this live on site, via stream or on demand.

One criticism of this HM2029 event from Siemens is they simply do not focus enough on the emphasis of Ecosystem management and what their Xcelerator platform can provide for their future growth, which is significantly more than at present in my opinion.

This is one case example where I would be wanting to understand where Siemens are in the Dual-Force Model. So let me offer this as a case study in validation and caution. They may not even recognize it as a growing problem for them! They need to.

Ignoring Ecosystems you DO face decline

Most organisations today are facing problems they cannot quite name. Their platforms are built, their partnerships are active, their digital investments are significant — yet the system still refuses to behave. They are deploying AI across the organization – yet it is not working.

Performance issues appear that don’t look like execution failures. AI pilots succeed locally but never scale. Sustainability efforts stall at the boundaries. Data accumulates without becoming advantage. Cross‑domain opportunities remain perpetually “almost there.” And coordination becomes heavier, not lighter, the more they invest.

Leaders feel this long before they understand it. They sense the friction. They see the misalignment. They watch the same issues reappear in different forms. They know something is structurally wrong — but nothing inside the organisation explains it.

This is the gap the IIBE exists to fill.
