Q-CTRL announced a US$290 million Series C on November 12, 2026, led by Salesforce Ventures, with significant participation from Affinity Partners and Bullhound Capital. The quantum software company says the financing makes it a quantum-sector unicorn. Its announcement doesn’t give an exact valuation. Source
Q-CTRL said the round was oversubscribed and expanded twice to accommodate investor demand. Source
According to the company, new investors include Affinity Partners, AMD Ventures, EDGE Group, MPower Partners, Australia’s National Reconstruction Fund Corporation and SPARX Asset Management. Returning backers include Salesforce Ventures, Bullhound Capital, In-Q-Tel and Lockheed Martin Ventures. The lead investor, in other words, is back for another helping. Source
Software, with a route beyond GPS
Q-CTRL describes its business as AI-powered infrastructure software for quantum computing and sensing. Its announced growth plans include expanding its software capabilities and global reach across sectors such as finance and energy, while continuing its autonomy and aerospace programs. Source
Salesforce Ventures partner Robert Keith explained the bet in Q-CTRL’s announcement: “The hard problem in quantum is not building the machine, it is getting useful output from it.” Source
Q-CTRL says its Ironstone Opal quantum navigation system works when GPS is unavailable or denied, and it plans to expand global deployment of its navigation systems. That puts the company’s ambitions beyond quantum computers in data centers and into navigation for aircraft and autonomous vehicles. Source
