Spinor Group Ltd secures £6.4m for on-site quantum computing

Guildford-based Spinor Group Ltd has raised £6.4m in a new funding round to support the development of its quantum computing hardware. The investment brings the company to an estimated post-money valuation of £454.4m.

Founded in 2019, Spinor Group Ltd builds compact, deployable superconducting quantum computers. The company focuses on providing on-site hardware for institutional operation, removing the requirement for cloud-based access. Its technical scope includes the manufacture of electronic instruments for measuring and testing, excluding those used for industrial process control. The firm also engages in business and domestic software development.

The company maintains a lean operational structure. Latest accounts show a headcount of two employees, while its LinkedIn profile lists one staff member. Spinor Group Ltd operates from its headquarters in Guildford and focuses on the computer hardware manufacturing sector.

This funding round was documented in filings during May 2026. The £6.4m raise follows the company's established focus on creating hardware that allows institutions to run quantum operations locally. The company's website indicates that its systems are designed for direct institutional use to ensure no cloud dependency. Spinor Group Ltd has been active in the Guildford tech sector since its incorporation seven years prior to this round.

The company's primary objective is the creation of superconducting quantum computers that are compact enough for on-site deployment. By focusing on hardware that does not rely on the cloud, the company addresses specific institutional needs for localized computing power. This latest capital injection of £6.4m will be used to further these manufacturing and development goals.
