In a world increasingly saturated with buzzwords and moonshot promises, Phasecraft has quietly—yet decisively—secured its place in the evolving quantum computing landscape. The UK-based startup, founded in 2019 by a trio of academic heavyweights—Toby Cubitt, Ashley Montanaro, and John Morton—has just raised $34 million in Series B funding. As of September 2, 2025, that brings its total funding (including grants) to over $50 million. And this round isn’t just about the money—it’s a signal that the center of gravity in quantum computing may be shifting from flashy hardware to the less glamorous, but utterly essential, realm of software.

Phasecraft’s mission is unapologetically ambitious: to write the algorithms today that will make noisy, imperfect quantum computers useful now, not in some far-off quantum utopia. Their software is hardware-agnostic and purpose-built for the current generation of NISQ (noisy intermediate-scale quantum) devices—a class of machines that can’t quite be trusted but can’t be ignored either. Phasecraft’s work effectively acts as the clever translator of the quantum world, bridging today’s hardware with tomorrow’s discoveries.
The Series B round was co-led by Plural, Playground Global (an existing investor), and Novo Holdings’ brand-new Quantum Fund—making its first-ever direct software investment. They were joined by returning backers LocalGlobe, AlbionVC, Parkwalk Advisors, and Latitude, underscoring Phasecraft’s growing credibility among both financial and strategic stakeholders.
What’s driving this vote of confidence? Simple: timing and traction.
Phasecraft is already deep in collaboration with leading quantum hardware players like Google Quantum AI, IBM, Quantinuum, and QuEra. Their industrial partnerships read like a who’s who of deep tech and infrastructure: Johnson Matthey, Oxford PV, the UK’s National Energy System Operator, and BT. The applications on the table—materials science, drug discovery, and energy resilience—are not just academically interesting; they are economically and environmentally urgent.
CEO Ashley Montanaro has set an aggressive, yet credible, goal: to deliver scientifically important quantum computations by spring 2026, with commercial deployments not far behind. That’s not a hypothetical milestone—it’s a countdown.
The broader context matters too. As with classical computing decades ago, quantum’s long game may not be won by the hardware arms race, but by the software that teaches these machines how to speak our language—and solve our problems.
Phasecraft is betting that algorithms, not qubits alone, will define the next chapter of quantum innovation. And if this funding round is any indication, the industry is beginning to bet with them.
