Building a 20M€ ARR App: My Journey
I didn't set out to build a 20M€ ARR app. It all started with a list of 100 dreams after Christmas 2019. Fast forward to today, and we're in 52 countries, tackling urban loneliness head-on. I orchestrated the development, navigated through financial challenges, and adjusted our business model to reach a global audience. This journey is more than just code; it's about human connection. In this article, I take you behind the scenes of our entrepreneurial journey, from the initial idea to managing global expansion. If you're ready to see how an idea turns into success, dive in with me.

I never intended to build an app that would generate 20M€ ARR. In fact, it all started with a simple list of 100 dreams after Christmas 2019. Back then, I was just trying to find a way to make life better in our often lonely cities. Fast forward to today: my app is in 52 countries, and I'm tackling urban loneliness head-on, a problem many see as insurmountable. But be warned, it hasn't been an easy road. I got burned a few times juggling development, fundraising, and the necessary pivots to adapt our business model for a global audience. In this article, I share the behind-the-scenes of our entrepreneurial journey, the challenges faced, the mistakes made, and the strategies that worked. If you want to understand how you turn an idea into a multi-million success, join me on this journey.
My Entrepreneurial Journey: From Dreams to Reality
Back in 2019, just after Christmas, I locked myself away with a journal and listed 100 dreams. Yes, 100. It was a pivotal moment, as I was at a crossroads in my professional life. Writing down these dreams gave a clear direction to my ambitions. But beware, it wasn't just a positive thinking exercise. From the start, the challenge was to clearly define the mission of the app I wanted to develop. The idea pivoted several times before crystallizing around a goal: combating urban loneliness.

The path hasn't been easy. We raised 2 million euros to last three years, but we had to learn to adapt quickly in an ultra-competitive industry. I met people, tested ideas, and most importantly, learned how to pivot without losing sight of our mission's essence.
Addressing Urban Loneliness: The App's Mission
Urban loneliness has become a major issue in big cities. I've seen it first-hand, and that's what motivated our app's mission. The idea was to create genuine social connections. Not just superficial meetings, but interactions that truly enrich users' lives.

In just a few years, the app has expanded to 300 cities and 52 countries. It's no small feat! Yet, it wasn't without challenges. We had to juggle between user experience and our mission-driven goals. And with global expansion, navigating cultural differences became crucial.
Scaling and Financial Management: The Backbone
Achieving an ARR (Annual Recurring Revenue) of 20 million euros is no accident. It's the result of a well-orchestrated growth strategy. Financial management is at the heart of this evolution. Raising 2 million euros was the first step. Then, we had to manage costs and ensure sustainability. For this, we built a robust backoffice system with a team of 15 developers.
We had to make tough choices, like reducing our monthly expenses to 5000-6000 euros to maintain an 8-month cash runway. Every euro counted, and it's in these moments that rigorous management makes all the difference.
Marketing and User Acquisition: Driving Growth
Making the app visible requires an effective marketing strategy. One of the levers was media coverage: 200 articles in a year, not bad, right? But that was just part of the equation. User acquisition must be cost-effective. We used ads, but watch out, you need to find the right balance between cost and reach. Understanding user acquisition cost and payback period is essential to avoid burning too much capital.
Sometimes, it's more effective to bet on viral content. I wrote an article on how to validate an app idea using viral content, and it served as a guide for many projects.
Pivoting and Business Model Evolution: Adapting to Change
You have to be ready to pivot when things don't go as planned. Evolving the business model is crucial to meet market needs. I've learned to savor failures and adjust strategies. Innovation must go hand in hand with business goals. That's what keeps you ahead in a highly competitive app market.

Through four pivots in three years, I've understood that adaptability is not just an asset but a necessity. You can read about a similar example in how to build a successful SaaS with Twitter.
- Don't be afraid to fail.
- Know when to pivot or improve an existing concept.
- Maintain a balance between innovation and business objectives.
Building an app to reach a 20M€ ARR is anything but straightforward. First off, it's not just about having a brilliant idea; it's about overcoming real challenges. From my experience, resilience is key, especially when you have to make strategic pivots — that's when your commitment to your mission really gets tested. And let's not forget those 200 press articles in one year, that didn't happen by chance, it came from a lot of sweat and strategy.
- Here are some concrete takeaways:
- Identifying the mission: It all starts here. When your mission is clear, it becomes your compass.
- Strategic flexibility: Be ready to pivot. It's these adjustments that make all the difference.
- Resilience: This is a marathon, not a sprint. Challenges are inevitable, but they shape your journey.
Looking ahead, this approach has shown me that ambitious dreams can become reality with the right strategies. Ready to tackle your own app challenges?
