QuTwo Raises €25M to Bridge Today's AI with Tomorrow's Quantum Computing

Helsinki-based QuTwo has closed a €25 million funding round at a €380 million valuation, the company announced yesterday. The startup, founded in February by Peter Sarlin—who previously built and sold AI company Silo AI to AMD for €665 million—positions itself as a bridge between today's classical computing and the quantum computing systems that are still being developed.

The funding attracted prominent investors including Yuri Milner from DST Global, Xavier Niel from Iliad, Supercell founder Ilkka Paananen, and Thomas Wolf from Hugging Face. Combined with an earlier €20 million seed round, QuTwo has raised €57 million in just four months.

From One Success to the Next

QuTwo emerged from Sarlin's family office, PostScriptum, which has incubated several AI companies. Sarlin deliberately frames QuTwo as an AI company rather than a quantum computing company—a choice that reflects a practical reality about where enterprise customers actually are today. He serves as executive chairman and also teaches machine learning at Aalto University.

The team combines quantum and AI expertise. Co-founder Kuan Yen Tan previously worked on quantum hardware at IQM, while Kaj-Mikael Björk was Sarlin's co-founder at Silo AI. This mix of quantum experience and enterprise software knowledge appears central to QuTwo's strategy.

What QuTwo Actually Does

QuTwo's main product, QuTwo OS, is software that routes computational work across different types of hardware: today's classical processors and accelerators (GPUs and CPUs), and eventually quantum processors as they mature. Think of it as a traffic director that decides which problems go to which type of computer, depending on what each is best at.

The company targets enterprises in finance, energy, retail, and life sciences—industries that routinely tackle complex optimization problems where quantum computing could eventually offer speed advantages. QuTwo has already assembled a 50-person team and is working with early customers.

The underlying bet here is interesting. Rather than building quantum computers themselves, QuTwo is focusing on the software layer that would let enterprises use quantum computers when they exist. In many ways, this mirrors what happened with cloud computing in the 2000s: the real value often came not from the infrastructure itself, but from the software and management tools that made it accessible to ordinary businesses.

A European Play on Computing's Next Wave

Sarlin has positioned QuTwo within a larger European strategy concern: Europe largely sat out the transition from CPUs to GPUs that made today's AI boom possible. His quantum focus reads as an attempt to establish European leadership in the next major computing shift—before it fully arrives.

This pattern has appeared before. Companies like SAP built enormous value by creating abstraction layers—software interfaces that hide complexity—over emerging infrastructure. Right now, quantum hardware is advancing toward commercial use, but enterprises have little guidance on how to actually integrate it. By building that integration layer now, QuTwo aims to become the default middle layer between quantum hardware and enterprise applications.

What's at Stake

The €380 million valuation at this early stage reflects investor confidence that the orchestration layer could be valuable, particularly if backed by proven AI expertise. Competitors like IBM and Google work on quantum hardware itself, but QuTwo focuses on the enterprise integration problem instead.

The rapid scaling—from launch in February to 50 employees and paying customers by May—speaks to Sarlin's reputation and to what appears to be genuine enterprise demand. Companies are willing to invest in quantum-ready infrastructure before the hardware is even commercially mature. This suggests they see real value in being ready early.

If quantum processors eventually deliver the advantages they promise for optimization and machine learning problems, enterprises using QuTwo OS would get earlier access to those capabilities without having to rebuild everything from scratch. The orchestration approach could reduce the friction of moving workloads to quantum hardware when the time comes.

Success will hinge on two things: whether quantum hardware actually delivers the performance gains it promises on real enterprise problems, and whether QuTwo's software layer provides enough value during the long transition period before quantum computing becomes mainstream. For now, strong investor interest and early customer adoption suggest there is real demand for infrastructure that positions enterprises for a computing transition that hasn't quite arrived yet.
