Building a sovereign stack
Everyone in Europe is talking about technological sovereignty. So I gave myself an assignment: build an entire media company using only European software. Here's day one.

This week, I started building a new media company in Europe about the intersection between business and tech. Whether or not you think that's an achievable goal — or even the right goal — one of the things on everyone's minds here is technological sovereignty: the idea that it's strategically important for Europe to own its own tech stack. So my first assignment to myself was to see if I could build purely on European software.
My first reaction was: thank God Europeans built the internet. Thank you, Sir Tim Berners-Lee, otherwise I would have been screwed. (I still was screwed.)
Because my first instinct was to ask the internet how exactly I was going to do this — and the first thing I realised was that I couldn't use Google. German-founded Ecosia it was, and thankfully Ecosia has a cosy little browser I could do all this research in.
Ecosia is an ad-powered search engine that uses all of its profits for climate action; it's planted over 250 million trees, making it the world's largest planter of native trees. Going through Ecosia's verdant onboarding process I thought: "Is this European values in practice?" I felt virtuous and searchuous.
An email before a model
Next, I wanted an LLM to help me research my transnational patriotic project. There was only one choice here: France's frontier model builder, Mistral. But before I could use it, I needed to make an account — which meant I needed an email. A European email.
A little Ecosia research later, I decided on German-built Mailbox.org. I chose it over several options, including Proton Mail, because it also provides calendar functionality and video calls. Never mind that the video-call area of the website is all in German. It's fine. Mailbox has functionality, but no style.
The branding of the different email offerings was a fascinating look at how one might differentiate in a world where Gmail and Outlook rule. Most went hard on privacy. Soverin, a Dutch alternative, was quoted as being “for email what Durex is for sex. Nice and safe.” Others went hard on sustainability: Runbox from Norway brands itself as the “world's leading hydropowered email service.” Why they're not number one, I'm not sure — and why they haven't built a website that doesn't look like it was made in 2012, I'm also not sure. I digress.
Where European ends
So I had my German email and my Mistral account — but I couldn't connect any apps in Mistral to bring outside context into my conversations. Outlook and Gmail connect easily; there is no Mailbox MCP (model context protocol, the API layer of LLMs) readily available. To make that connection and have reliable, always-on access to my email through Mistral, I'd need a virtual private server — my own little slice of a machine. The European option favoured by engineers is, again, German: Hetzner.
I've signed up for Hetzner, which will cost me a few euros a month — but Hetzner is notorious for its verification checks. Because it's so cheap, scammers love it, so I need my physical passport to get verified, and I can't do that until I'm home. Sigh.
The Hetzner signup also showed me the limits of choosing European. While Hetzner's servers are located in Germany, the chips they run on are American. It was a reminder that digital sovereignty has to cross into the physical world at some point. (And one could argue I'm cheating on this whole exercise by typing on a Chinese-built keyboard, using a Mac.) Hardware, crushing my sovereign dreams.
The word-processing part was the easiest — sweet relief. A team of ex-DeepMind engineers is building a Google Docs alternative in London called Marker, which I've been using for months.
How long is a piece of string?
After day one, my conclusion is that this task is the software equivalent of asking how long a piece of string is. Software is built on so many layers that it's hard to separate out anything truly European. I'm also aware I'm looking for solutions that fit a small startup — at the enterprise level, “hydropowered email” probably doesn't fly.
I was struck by the marketing of these tools, and their focus on values like environmental friendliness and security. People say they care about those things — but do they choose products based on them? There's little evidence they do, broadly. Coming up in my stack: I'm talking to Slack alternative Slashwork on Monday to get onboarded, and I'll finally get verified on Hetzner.

Day 2 is coming and I need your help: what European tools belong in the stack? I'm onboarding to Slashwork on Monday, but I'm missing analytics, payments and a CRM. Hit me with your picks — the weirder and more local, the better.
The "German servers, American chips" realisation is the whole ballgame. We hit the exact same wall. You can get to ~90% European on the software layer surprisingly fast — it's that last 10% at the silicon level where the dream dies. For now.
Exactly my experience, Júlia. The keyboard I'm typing this on is undermining me as we speak.
Add Tuta for email and Nextcloud for storage and you're most of the way there. But your point about marketing is the sharp one — "hydropowered email" is a values pitch, and procurement teams buy on reliability and price. Sovereignty needs a business case, not just a virtue.
