Company History and Business Evolution (450+ Words)

Phasecraft was co-founded in 2019 by three prominent quantum researchers: Professor Steve Flammia, Dr. Toby Cubitt, and Dr. Ashley Montanaro. The founders recognized that while quantum hardware was advancing rapidly, the software layer required to harness that hardware was underdeveloped. They set out to build a company that would specialize in creating highly optimized algorithms for the NISQ era. The company's early development was fueled by a £1.3 million seed investment from LocalGlobe, a leading London-based venture capital firm, and a grant from the UK's Innovate UK agency. In 2020, Phasecraft published groundbreaking work demonstrating that quantum circuits with as few as 40 qubits could solve problems in materials science that classical computers found intractable. This research attracted attention from major hardware vendors, leading to collaborations with Google Quantum AI in 2021. That same year, Phasecraft moved into a dedicated office in London's King's Cross district, expanding its team to 15. A milestone came in 2022 when Phasecraft secured a £13 million Series A funding round led by Balderton Capital, with participation from Episode 1 and existing investors. The funding enabled expansion into new application areas, including quantum chemistry for drug discovery and optimization for logistics. In 2023, Phasecraft launched its proprietary software development kit, Phasecraft SDK, which became the go-to tool for developers working on NISQ devices. The SDK integrated with popular platforms like Qiskit and Cirq, and included specialized modules for error mitigation and compilation. By 2024, Phasecraft had grown to over 40 employees, with a second office in Bristol near the University of Bristol's quantum research center. The company also received a prestigious grant from the European Commission's Quantum Flagship program. Throughout its evolution, Phasecraft has maintained a strong publication record, with over 30 peer-reviewed papers in top journals such as Physical Review Letters, Nature Communications, and Quantum. The company has also filed several patents covering key innovations in circuit optimization and noise-aware compilation. Phasecraft's evolution reflects a deliberate strategy: start with fundamental research, build practical tools, and then commercialize through partnerships and licensing. This phased approach has allowed the company to de-risk its technology while staying at the forefront of scientific advances. Looking ahead, Phasecraft is exploring spin-out ventures in specific verticals, such as quantum-powered weather forecasting and battery cell simulation, signaling a shift from pure research to product-led growth.
