Aqarios Goes Public as Germany’s First Pure-Play Quantum Computing Company

This marks one of the biggest milestones in Aqarios’ journey so far. As of this week, Aqarios is publicly listed — becoming, to our knowledge, the first pure-play quantum computing company to be listed on a German stock exchange.

Following a successful SPAC transaction with Fonterelli SPAC 4 AG, Aqarios has officially entered the public markets under the name Aqarios Quantum Technologies AG. Our shares now trade on the Düsseldorf Stock Exchange (Börse Düsseldorf). While our mission remains the same — making quantum computing practical and accessible for businesses — this new chapter provides us with an even stronger foundation to accelerate innovation, expand our platform, and bring quantum solutions to more industries than ever before. 

“Quantum computing will help determine industrial competitiveness in the years ahead — and we want that value creation to happen in Germany and Europe,” says Michael Lachner, CEO of Aqarios Quantum Technologies AG. “As, to our knowledge, the first publicly listed quantum software company in Germany, we’re making this future technology as accessible to investors as it already is to our industrial customers. With Luna, we’ve shown that quantum computing is relevant for businesses today — hardware-agnostic, application-driven, and scalable.”

From University Spin-Off to Public Company

Founded in 2021 as a spin-off from LMU Munich, Aqarios started with a clear vision: bridge the gap between cutting-edge quantum research and real industrial applications.

Over the past few years, we’ve grown from a small research-driven startup into a trusted technology partner for leading industrial companies. Today, our team develops quantum optimization software built to help organizations solve some of their most complex challenges — from optimizing supply chains and energy grids to manufacturing processes and investment portfolios.

Along the way, we’ve had the opportunity to work with renowned partners including BASF, E.ON, and MTU Aero Engines, while contributing to some of Germany’s most ambitious quantum research initiatives.

For us, going public is where the next phase begins — with the resources to keep investing in our platform, our team, and our customers.

Building Practical Quantum Computing with Luna

At the heart of everything we do is Luna, our quantum application platform.

Luna enables companies to leverage quantum computing without requiring in-house quantum expertise. Instead of worrying about hardware, algorithms, or infrastructure, users can focus entirely on solving their business challenges while Luna automatically selects and orchestrates the best available technologies.

One of Luna’s key strengths is its hardware-agnostic approach. Customers are never locked into a single quantum hardware provider and can seamlessly access multiple quantum systems through one unified platform. By combining classical and quantum computing, Luna ensures that every optimization problem is solved using the most effective technology available today.

This practical approach has already been recognized by the industry, including receiving the Quantum Effects Award 2025 for Quantum Computing Software and Algorithms.

Strong Partnerships, Stronger Innovation

Innovation has always been a collaborative effort.

Aqarios is part of QuCUN (Quantum Computing User Network), a major German research initiative alongside SAP, BASF, and LMU Munich, supported by the German Federal Ministry for Research, Technology and Space (BMFTR). Together, the consortium is building an open and sustainable quantum computing ecosystem for Germany.

Beyond research, we’re continuously bringing quantum technology into real-world business applications. One exciting example is our collaboration with fintech company Divizend, where we’re developing a new portfolio optimization solution powered by the Luna platform.

These partnerships demonstrate our commitment to turning quantum computing from an emerging technology into a practical business tool.

A Strong Foundation for the Next Stage of Growth

This step reflects the progress we’ve made over the past years, the trust our customers and partners have placed in us, and the opportunities ahead. As Aqarios Quantum Technologies AG, we’re well positioned to continue expanding our technology, growing our customer base, and helping shape the future of industrial quantum computing.

For our customers and partners, nothing about our commitment changes — only our ability to deliver on it grows. The same team, the same platform, now with a stronger foundation to invest, hire, and scale.

Leading this next chapter is our management team under CEO Michael Lachner, together with a supervisory board combining deep expertise in finance and quantum technologies. The board is chaired by Dr. Sebastian Kern, with Dr. Sebastian Feld, Professor at TU Delft, as Vice Chairman, and Dr. Thomas Gabor, Research Fellow at the University of Exeter, completing the supervisory board.

Their combined experience will help guide Aqarios through its next phase of growth as a publicly listed company.

Looking Ahead

Quantum computing is rapidly moving from research labs into industrial applications, and Germany has become one of the world’s strongest ecosystems for quantum innovation.
As a company founded from world-class research and built around practical software solutions, we’re proud to contribute to that ecosystem — and even prouder to be Germany’s first publicly listed pure-play quantum computing company.

This is an exciting moment for our team, our customers, our partners, and everyone who has supported Aqarios from the very beginning.

And we’re just getting started.

Thank you for being part of our journey. The next chapter begins now.
