- Finnish quantum simulation startup Quanscient has raised €10M in a Series A led by 55 North, the world’s largest dedicated quantum fund, bringing total funding to approximately €19M.
- The deal marks 55 North’s first investment in a simulation software company, signalling a broadening of quantum venture capital beyond hardware into AI-native engineering tools.
- 89% of engineers routinely simplify their physics models just to meet runtime budgets, according to Quanscient’s own research, the problem the platform is built to solve.
Hardware engineering has an AI problem, and it is not the one most people discuss. While language models transform software, the tools engineers use to design physical products, turbines, semiconductors, electric motors, still run on legacy simulation software that requires weeks per test and forces engineers to cut corners on physics just to hit deadlines. Quanscient is building the alternative, and it just secured the most high-profile backing in its four-year history.
The Tampere-based company announced a €10 million Series A today, led by 55 North, a Copenhagen-based fund that closed at €134M in October 2025 and is targeting a €300M final close, making it the world’s largest dedicated quantum technology venture capital fund. Austrian industrial holding B&C Group joined as a new investor alongside a full re-participation from existing backers Maki.vc, Crowberry Capital, QAI Ventures, and First Fellow Partners. The round brings Quanscient’s total funding to approximately €19M, following a €5.2M round led by Crowberry Capital in November 2024.
What Quanscient does
Founded in September 2021 by Juha Riippi, Alexandre Halbach, Asser Lähdemäki, andValtteri Lahtinen, with Andrew Tweedie joining as a fifth founder in 2024, Quanscient builds multiphysics simulation software: tools that model how physical forces such as heat, fluid flow, electromagnetics, and mechanical stress interact simultaneously inside a product design. The platform runs in the cloud via a code-driven API, delivering simulations up to 100 times faster than on-premise alternatives and cutting runtimes by up to 99%.
The practical result is that an engineer testing a motor design, a fusion reactor component, or an aircraft part can run hundreds of design variations in the time it previously took to run one. Current customers include Fortune 100 companies across energy, aerospace, and automotive, spanning Europe, North America, and Japan.
The novel layer Quanscient is now adding is AI integration: by generating the high volume of multiphysics data that AI models need to learn from, the platform aims to train physics-aware AI that can autonomously suggest or optimise hardware designs — something no existing simulation tool does at scale.
“AI will not transform hardware engineering unless simulation itself is rebuilt for it,” said Riippi. “By making multiphysics code-driven and cloud-scalable, we generate the volume of physics data that AI needs, turning simulation from a bottleneck into the engine of data-driven design.”
The investors
55 North’s portfolio already includes IQM Quantum Computers, which raised €275M in a Series B, and Kiutra, a cryogenic cooling startup. The fund is led by Managing Partner Dr Owen Lozman alongside General Partners Dr Helmut Katzgraber, formerly of Amazon and Microsoft, and Dr Kai Hudek, formerly of IonQ. Quanscient is the fund’s first simulation software investment and its first Finnish portfolio company.
B&C Group is the core shareholder in Austrian industrial giants AMAG Austria Metall, Lenzing, and Semperit, and invests in industrial tech startups through its venture arm BCII. The firm acts as a long-term minority investor without exit pressure — structurally unusual for a Series A co-investor and a deliberate signal of industrial credibility.
“Engineering teams are under pressure to explore much larger design spaces and more complex physics than legacy tools were built for,” said Helmut Katzgraber, Chief Science Officer and General Partner at 55 North. “Quanscient’s cloud-native multiphysics platform, combined with forward-looking work on quantum algorithms and AI tools, gives customers a future-proof step-change in throughput without sacrificing accuracy.”
The competitive landscape
The established simulation software market is consolidating fast. Synopsys completed its $35 billion acquisition of Ansys in July 2025, creating the dominant incumbent. Siemens agreed to acquire Altair for $10.6 billion in October 2024, with the deal closing in 2025. COMSOL, the Swedish multiphysics specialist, remains privately held. All three rely primarily on on-premise or licence-based models, and none has yet integrated quantum algorithms into their core product.
Quanscient’s differentiation is the cloud-native, API-first architecture, which makes high-volume simulation economically viable, combined with the quantum algorithm layer that incumbents have not yet built. The company employs 40 people across 15 nationalities. The multiphysics simulation software market was valued at $551M in 2025 and is projected to reach $905M by 2033 at a CAGR of 6.4%, according to Congruence Market Insights; the broader simulation software market, at $19.95 billion in 2024, is forecast to hit $36.22 billion by 2030 at a 10.4% CAGR.
The deeper question the Quanscient raises is whether the real prize in quantum computing is not in the hardware at all, but in the software layer that makes physics-based AI possible. If 55 North, with its focus on the entire quantum stack, is betting that simulation is where quantum first proves its industrial value, the rest of the market may need to catch up.
