The Tampere startup wants to rebuild physics simulation as the data engine for AI-driven hardware design.
Tampere-based Quanscient has closed a €10 million Series A to scale its cloud-based multiphysics simulation platform, in a round led by Danish quantum fund 55 North and Austrian industrial investor B&C Group, with full re-participation from existing backers Maki.vc, Crowberry Capital, QAI Ventures, and First Fellow Partners.
The company, founded in 2021, builds simulation software for engineers designing physical products: motors, antennas, fusion magnets, the kind of hardware where small errors in a model become expensive corrections in metal.
Quanscient pitches its platform as code-driven, cloud-scalable, and built to generate the volume of multiphysics data that machine-learning models will need to learn from.
The Series A is earmarked for international expansion and for what the company describes as the market’s first platform to unify simulation, quantum algorithms and AI integration.
The funding lands at a moment when hardware engineering is, as Quanscient’s own 2025 study argues, stuck. According to the company’s survey, 89% of engineers routinely simplify their physics models to fit within runtime budgets.
The implication is that the data generated by current simulation workflows is not rich enough to train the kind of physics-aware AI models that the next generation of design tools will rely on.
Quanscient’s platform claims simulations up to 100 times faster than incumbent tools, which the company says cuts runtimes by up to 99%.
“AI will not transform hardware engineering unless simulation itself is rebuilt for it,” said Juha Riippi, Quanscient’s co-founder and CEO.
“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 lead investor is itself new to the European venture map. 55 North, headquartered in Copenhagen, announced the first close of its €300m quantum fund in October 2025 at €134m, and is currently the largest dedicated pure-play quantum venture vehicle in the world.
The firm is led by Owen Lozman, formerly of M Ventures, alongside Helmut Katzgraber, a computational physicist previously at Amazon and Microsoft, and Kai Hudek, formerly of IonQ.
Quanscient is one of the fund’s first publicly disclosed investments, alongside Finnish quantum-hardware unicorn IQM and German cryogenics specialist Kiutra.
“Engineering teams are under pressure to explore much larger design spaces and more complex physics than legacy tools were built for,” said Katzgraber, who is 55 North’s chief science officer and general partner.
He flagged nuclear fusion, advanced electronics and quantum technologies as the customer segments where Quanscient’s throughput claims matter most.
B&C’s participation is through B&C Innovation Investments, the industrial-tech arm of the Vienna-based group, which is majority owner of Lenzing, AMAG and Semperit.
“We see technologies like these as key to strengthening Europe’s industrial innovation capacity in the long term,” said Julia Reilinger, BCII’s managing director.
Quanscient was founded by Riippi, Alexandre Halbach, Asser Lähdemäki and Valtteri Lahtinen in 2021, with Andrew Tweedie joining as a fifth co-founder in 2024.
The company employs 40 people across 15 nationalities and counts Fortune 100 manufacturers among customers in Europe, North America and Japan.
Prior to this round, Quanscient had raised roughly €9m across earlier seed and growth tranches, including a €5.2m round led by Crowberry Capital in late 2024.
