QuantrolOx, EUR 12M Series A for software that tunes quantum hardware
According to the company, its machine learning tuned quantum devices in under 70 minutes, outperforming the best human benchmark. On 22 October 2026 QuantrolOx, a spinout of the University of Oxford, announced a €12 million Series A.
The round was led by IW Capital. The EIC Fund and Transpose Capital also invested, and Hoxton Ventures and Hermann Hauser are among the existing investors. On its own page the EIC Fund describes itself as the venture capital investment arm of the European Innovation Council, financed by the European Commission. How much it put in, and the split between investors, is not published.
QuantrolOx sells software that automates the tuning and control of quantum computers, which the company calls a current bottleneck in quantum. It says the software works across different hardware architectures. Its website names the platform Quantum EDGE, dates the company to 2021 and says it has customers and partners in 13 countries.
Where it is based depends on the source. tech.eu calls it Anglo-Finnish and says it is headquartered in Finland. The company's site lists offices in Oxford, Espoo, Delft, Bengaluru and Berkeley, names a Finnish entity, and does not say which office is the headquarters.
Of the four founders tech.eu names, Andrew Briggs and Natalia Ares hold Oxford posts, and Dominic Lennon did his DPhil there. CEO Vishal Chatrath says: "Our tools industrialise quantum hardware and train the people to run it."
The limits: no valuation is published, and tech.eu does not name the research behind the 70-minute result. No revenue figure is published.
What the money pays for: speeding up commercial growth and funding the company's efforts in the US.
