How to Launch a Consumer Crypto App in Europe

On paper, Europe is one market. On a phone screen, it's 27. This is the playbook I wish someone had handed me before my first launch: where to start, what to localise, where growth actually comes from, and how to stay close enough to your users to know what's working.

I've done this twice. At Bitpanda, as Head of Marketing, we grew from around 100,000 to over 1.1 million users. At Relai, I led the expansion from Switzerland into Germany, Italy, Spain and beyond, running growth in five languages. Monthly active users grew 10x in two years, and around 70% of this year's signups are organic.

This is written for founders and growth leads at consumer crypto and fintech companies (savings, investing, payments, neobanking) who are about to cross a European border. That could be your first one as a European scale-up, or your first one as a US, UK or Swiss company with a fresh EU licence.

01Start with a beachhead, not a map of Europe

A single EU licence lets you serve every member state. Most teams read that as "launch everywhere". It's the most expensive way to get noticed nowhere.

Europe, the UK included, has a long list of half-committed entries. Robinhood built a UK waitlist of 250,000 people, then postponed the launch in 2020 to focus on the US.¹ Wealthsimple sold its UK book of around 16,000 customers in 2021 because "it's about focus".² Public.com closed its UK operation after about eight months.³ None of these were bad products. They were spread too thin.

The alternative is a beachhead strategy, from Geoffrey Moore's Crossing the Chasm. Pick one market that is big enough to matter and small enough to lead. Put everything into winning it. Then use it as the base to take the markets next to it, one at a time, like bowling pins.⁴ In European consumer fintech, that market is usually a country or a language region.

So which one? The common answer is "wherever you already have product-market fit". That's half right. Your home market proves the product works, but it isn't always big enough to be the beachhead. The better answer: the biggest market closest to the fit you already have. Same language, similar habits, so what already works carries over with as little change as possible.

That's exactly what happened at Relai. We launched in Switzerland, and Germany became our key market almost by itself. It shares the language, so the product, content and support carried straight over. It's one of the most important markets in European fintech. And it fits a savings app perfectly, because Germans are savers. Germany's gross household saving rate was 20% in 2024, against an EU average of 14.6%.⁵ German households hold around €10 trillion in financial assets, much of it sitting in low-interest overnight accounts.⁶ Germany is our beachhead.

Before you commit, test your candidate on three questions:

• Is it close to your existing fit? Same language or very similar habits, so your product, content and support work with little change.
• Is it big enough to matter? Winning it should change the trajectory of the company on its own.
• Can you become one of the names people mention? If the realistic outcome is number seven in a crowded market, pick a different beachhead or a narrower segment within it.

Only add the next market once the beachhead keeps compounding without you managing it every day: organic share rising, referrals flowing, and users who'd be very disappointed to lose you (more on that in 06). Then move to the closest neighbour. For a German beachhead, that's usually Austria.

02Localise the plumbing, not the product

Revolut and Trade Republic look like opposites. Revolut runs 38 markets on a single app and favours a standardised approach.⁷ Trade Republic talks about "deeply localized offerings".⁸ Look closer and they've converged on the same thing.

Trade Republic's co-founder Christian Hecker advises sticking to one business model in every country, because country-specific solutions kill economies of scale.⁹ Yet both companies localise the layer where money moves. In 2022, Revolut moved around 2 million French customers onto French IBANs, because employers and utilities kept refusing foreign ones.¹⁰ Trade Republic rolled out national IBANs and local savings products in its biggest markets.⁸

In practice, that means three things per market, before any campaign:

• Top-ups the way locals pay. The moment someone tops up is the moment of highest intent. If the method they use every day isn't there, you lose them right there.
• A local IBAN where it matters. Especially if you want salary deposits or direct debits.
• Native-language support from day one. Support gets rated far better when the agent speaks the customer's language. A translated help centre with an English chat queue doesn't count. In CSA Research's study of 29 countries, 75% of consumers said they're more likely to buy again from a brand that offers customer care in their language. In Germany, 57% only buy from websites in their own language.¹¹

03Make search the front door, in every language

Before Europeans put savings anywhere, they research, in their own language. That used to mean Google and the app stores. Increasingly, it means asking an AI assistant. People ask ChatGPT whether your app is safe, how you compare with the alternatives, or simply "what's the best app to save in Bitcoin?" If you aren't in that answer, you don't exist for that person.

For classic search, that means native content per market, written for the questions locals actually ask, and app store listings with local keywords, screenshots and reviews. Start six months before you need the traffic, because search compounds slowly and then all at once.

For AI search, four habits make the difference:

• Ask the questions yourself, every month. Run your category and brand questions in ChatGPT, Gemini, Perplexity and Claude, in each local language, and log whether you're named and what's said about you.
• Describe yourself the same way everywhere. Website, app stores, LinkedIn, press releases. Assistants piece together who you are from many sources, and a consistent description is easier to repeat.
• Publish plain answers to the obvious questions. Fees, safety, who's behind the company, how to get your money out. In every language you operate in.
• Earn mentions on other people's sites. Comparison sites, local press and podcasts carry more weight than anything you say about yourself.

At Relai, this is the backbone of growth: top-5 rankings in Germany and #1 in Switzerland for core Bitcoin buying and savings searches, behind only Coinbase, Kraken, Bison and Ledger, and around five times the AI-search visibility of our Bitcoin-only peers.

04Build the organic engine first. Paid comes second

Paid acquisition for crypto in Europe is expensive, and the big ad platforms limit what you can run. Creative that works in one market often falls flat in the next, so brief and test per country instead of translating one campaign.

The organic engine (search, referral, community, local press) is slower to build and much harder to copy. Irina Scarlat, Revolut's former Global Head of Growth, joined as Romania country manager at around 20,000 users and grew it towards 1.5 million. It became the first Revolut market to grow faster than the UK, with no budget.¹² Her tools were community events open to non-users, active users turned into ambassadors, and one well-timed promotion (a free card for five days) that took the market from 75,000 to 100,000 users.

The strongest organic lever is a great referral programme. It's the cheapest acquisition channel you'll ever build, and new users who arrive through a friend already trust you a little. What separates a great one from a forgettable one:

• Reward both sides. The person inviting and the person joining.
• Reward in something that belongs to the product. For a savings or investing app, a small amount of the asset itself beats a voucher. It gets the new user started.
• Ask at the moment of delight. After the first successful purchase or a savings milestone, not on day one.
• Keep it explainable in one sentence. If people can't repeat it to a friend, they won't.
• Track it per country. Referral share is one of the best early signs that a market is working.

Irina's test for real product-led growth is worth stealing: people referring you without any incentive at all. At Relai, around 70% of 2026 signups are organic. Paid media is the accelerator, not the engine.

My rule: don't switch on paid in a new market until organic signups convert and 90-day retention looks healthy there. Paid amplifies whatever is already there, including a leaky funnel.

05Build a brand people feel safe with

People are trusting you with their savings. In a new market, nobody knows you yet, and the first question isn't "is this the best app?" It's "is this safe?" Your brand has to answer that before your features get a chance.

Three things build that feeling:

• Consistency. The same promise, voice and look in every market and at every touchpoint: ads, app, push notifications, support replies, the founder's LinkedIn. Inconsistency reads as risk. Translate the tone, not just the words.
• Authenticity. Real people and real faces, including local ones. Plain language about fees and risks. No hype, and a brand that sounds the same in a bull market and a bear market.
• Visible proof. Who's behind the company, where it's based, that it's licensed, how fast support answers, real reviews, and local press. Small things, but together they're what people check before they transfer their first euro.

Write your brand down on one page: what you promise, how you sound, what you never do. Then check every market's creative against it. At Relai, the brand is the part people compliment first, and that's no accident. Trust compounds the same way search does.

06Know your users better than your competitors do

Every market tells you something different, but only if you ask. Dashboards tell you what users do. Surveys and conversations tell you why.

My favourite tool is the Sean Ellis product-market fit survey. Ask active users one question: "How would you feel if you could no longer use [product]?" They answer very disappointed, somewhat disappointed or not disappointed. If 40% or more say very disappointed, you're on to something.¹³ Run it per country. It's the clearest signal I know of whether your beachhead is won or still being fought for. Then read the follow-up answers: what kind of person benefits most, the main benefit they get, what they'd use instead, and what would make it better.

Beyond that, keep a few questions running all the time:

• Why did you pick us? And what did you compare us with? This is your real positioning, in your customers' words.
• How did you hear about us? One optional question with a free-text field during onboarding. It picks up word of mouth, podcasts and AI assistants that your tracking will never see.
• What almost stopped you signing up? Each answer is a conversion problem you can fix.
• How is the product experience? Ask after key moments, not at random.

Ask in the local language, read the answers yourself rather than only the summary, and talk to a handful of users in each market every month. Some of the best messaging you'll ever write comes almost word for word from customers.

Checklist: before you spend a euro on media

• You've picked one beachhead: close to your existing fit, and big enough to matter
• The payment method locals use most is live for top-ups
• A local IBAN is available, or you know why you don't need one
• The app, website and help centre are written by native speakers
• Native-language support is staffed for local working hours
• Local search content and app store listings have been live for months, not days
• You know what ChatGPT, Gemini and Perplexity say about you and your category, in the local language
• The referral programme is live, rewards both sides and is tracked by country
• Your one-page brand guide exists, and local creative has been checked against it
• Local press contacts and the first community events are lined up
• The PMF survey and "how did you hear about us?" are running in the local language

If you only do three things

• Pick your beachhead and say no to everything else until it grows without you watching it every day.
• Get native-language payments and support right there before a single campaign goes live.
• Run the PMF survey every quarter in that market, and build your next roadmap and messaging around what the "very disappointed" users tell you.

Frequently asked questions

Which European country should a crypto or fintech app launch in first?

The biggest market closest to the product-market fit you already have: same language or similar habits, so the product, content and support carry over with little change. Relai launched in Switzerland and made Germany its beachhead, because it shares the language, is one of the most important fintech markets in Europe and has a strong savings culture.

What is a beachhead market strategy?

An idea from Geoffrey Moore's Crossing the Chasm: pick one market that is big enough to matter and small enough to lead, put everything into winning it, then use it as the base to take neighbouring markets one at a time, like bowling pins.

What should a fintech localise when it enters a new European country?

Keep one product, one brand and one growth engine. Localise the layer where money and trust meet the customer: the payment methods locals use to top up, a local IBAN where salary deposits or direct debits matter, native-language content and native-language support.

How do you know a new market is working?

Organic share keeps rising, referrals flow without heavy incentives, and at least 40% of active users in that market say they would be very disappointed if they could no longer use the product, the Sean Ellis product-market fit benchmark.
