Is Your Marketing Stack Actually Yours?

You've built a marketing stack. You've invested in platforms, connected your tools, and hired people to run them. On paper, you're in control. 

But how much of that stack do you actually own? 

Not contractually, but operationally, legally, strategically? 

The platforms you depend on to reach your customers, manage their data, and run your campaigns — who owns them? Where are they governed? And what happens to your business if your vendors raise prices by 30%, retreat from your market, or are compelled by a foreign government to hand over your customer data? 

This is digital sovereignty. 

It's the question of whether you or someone else is ultimately in control of your marketing. 

For European marketing leaders, this has become one of the most important strategic questions of the decade. The organisations that answer it well will have a major advantage: 

• lower costs
• cleaner data governance, faster execution
• the freedom to make strategic choices they can count on

The ones that don’t will sooner or later find themselves far more limited than they might think: Limited by vendor contracts, by foreign law, and by a stack that's harder and harder to change. 

What is digital dependency? 

Digital dependency is what happens when your marketing stack becomes so entangled with foreign platforms and systems that you've lost the ability to act freely. 

It happens slowly as you add a platform here, an integration there, and in the end, it feels too risky and too expensive to change anything. 

Most European marketing stacks are somewhere in between sovereignty and dependency. 

They have a mix of solutions operating under different standards and jurisdictions. Some European, some American, some operating from elsewhere in the world. 

If marketing leaders actually sat down and mapped out where exactly their dependencies are, they might be quite uncomfortable with what they find.

The risks are real 

Six clear risks come with digital dependency, and they all interact and make each other stronger: 

• Higher Total Cost of Ownership: Monolithic platforms are systematically more expensive than composable alternatives over 5 years. The initial price might not be so bad, but the cost of customisation and integration accumulates over time. Importantly, since exiting a monolithic platform is so complicated, they can easily raise their prices and count on you to absorb the cost. 
• Platform lock-in: The tighter your integration with a monolithic platform, the more difficult and expensive it becomes to change anything. When your CMS, your customer data, your campaigns, and your commerce are all running through one vendor's infrastructure, leaving has enormous consequences. This means that many organisations become paralysed and end up using the same, expensive, outdated system that no longer suits their business goals.  
• Foreign law reaches into European data: The U.S. Cloud Act means that if your platform is owned by a U.S. entity, U.S. authorities can compel access to your data. Yes, this is also true for data stored in European data centres. That's a direct conflict with your GDPR obligations, which are your responsibility to protect as data owner.  
• Vendor priorities aren't your priorities: U.S. platform vendors answer to U.S. investors. This means that, when market conditions shift, European markets can quickly be deprioritised, underinvested, or exited completely. You may be a significant customer locally, but globally, you’re barely a drop in the ocean. When you need support, this means that your request might get lost at the bottom of the pile. 
• SaaS prices are rising fast: Major vendors raised prices by 7–50% between 2024 and 2025. Faced with major price increases, most organisations consider changing solutions. But when you’re locked in, it’s much harder to do that. When it's so difficult to change solutions, vendors can raise prices and count on you to eat the cost. The organisations with composable, flexible stacks have much more room for negotiation and can actually walk away from the table. 
• ESG misalignment is growing: Non-European platforms don't always meet European standards for carbon intensity, data governance, or transparency. This makes it harder to stay on top of your own commitments and your stakeholders' expectations. As ESG reporting requirements tighten across Europe, this affects both your reputation as well as your compliance.  

All these risks are happening right now in most European marketing stacks. Chances are you're already exposed, so the only question is how much and what you can do to change it. 

Where do you stand? Four questions worth considering 

• Which platforms in my stack are owned by non-European entities? 
• Which of those would be painful (or practically impossible) to leave? 
• Where is my customer data, and who legally has access to it right now? 
• If one of my key vendors raised prices by 30% next year, what would I actually do? 

If any of those questions are hard to answer or make you a bit uncomfortable, this is a strong sign that you need to evaluate your digital sovereignty. 

The good news 

Digital dependency is something that can be improved. It doesn’t require you to start over, and you don’t need to choose between either a rigid suite or a series of composable solutions that don’t speak together.  

There’s a third option, orchestration: connecting data, content, activation, and commerce into a composable, sovereign whole where each part can be changed without destabilising everything else. And importantly, with all individual components based in Europe, you know exactly what jurisdictions and compliance they’re all operating under.
