Munich-based quantum optimization software provider Aqarios GmbH has completed a public listing on the Düsseldorf Stock Exchange (Börse Düsseldorf) through a reverse merger transaction via a Special Purpose Acquisition Company (SPAC). Following a successful combination agreement with Fonterelli SPAC 4 AG, the newly combined capital market vehicle has been formally renamed Aqarios Quantum Technologies AG. The structural transaction marks a milestone for the European deep-tech ecosystem, establishing the company as the first publicly traded pure-play quantum computing corporation on a German stock exchange.

Commercial Scaling from Academic Foundations

Founded in 2021 as a research spin-off from the Ludwig-Maximilians-Universität München (LMU Munich), Aqarios operates an application-oriented software pipeline designed to solve mathematically intense combinatorial optimization problems. Rather than developing hardware, the 15-person engineering firm builds algorithmic bridges to optimize real-world asset logistics, energy grid transmission loads, factory production planning, and multi-variable investment portfolios. The company has already completed pilot software integrations with DAX-listed blue-chip enterprises and industrial operators, including BASF, E.ON, and MTU Aero Engines.

Financially, the company has operated on a combination of customer project revenues and competitive deep-tech innovation grants, generating steady annual receipts fluctuating between €1.16 million and €1.37 million across the 2023–2025 fiscal years. While reporting net annual results between a positive €193,000 and a net loss of €459,000 due to aggressive R&D capitalization into its platform infrastructure, the public listing is structured to provide the expanded visibility and capital access necessary to transition the platform into a recurring SaaS licensing model.

Orchestrating Hybrid Computations via the Luna Platform

At the center of the company’s commercial strategy is Luna, a proprietary application platform engineered to lower the entry barriers for enterprise quantum adoption:

  • Hardware-Agnostic Abstraction: Luna functions as an abstraction middleware layer, insulating corporate end-users from the underlying physical differences of competing hardware platforms. Customers can route execution scripts to various quantum processors without being locked into a single hardware vendor.
  • Hybrid Classical-Quantum Execution: Recognizing the limitations of modern Noisy Intermediate-Scale Quantum (NISQ) processors, Luna intelligently splits computational workloads. The platform automatically assigns linear operations to classical high-performance computing (HPC) environments, reserving the quantum processor exclusively for hyper-complex optimization loops.
  • Vertical Fintech Expansions: The company is expanding the platform into sector-specific verticals, including a joint product venture with fintech firm Divizend GmbH to roll out a specialized, quantum-accelerated portfolio optimization solution for private and institutional asset managers.

To build out Germany’s sovereign computing footprint, Aqarios serves as a core consortium lead in the Quantum Computing User Network (QuCUN). Backed by a €14.2 million total funding grant from the German Federal Ministry for Research, Technology, and Space (BMFTR), Aqarios collaborates alongside SAP, BASF, and LMU Munich to establish open ecosystem standards for industrial quantum deployment across Europe.

The newly public entity is led by Co-Founder and CEO Michael Lachner. The corporate supervisory board combines targeted financial and specialized quantum architecture expertise, chaired by private equity veteran Dr. Sebastian Kern, alongside Vice Chairman Dr. Sebastian Feld (Professor of Quantum Architecture at TU Delft) and Dr. Thomas Gabor (Quantum-AI Research Fellow at the University of Exeter).
