€19.6m · Series A · Deeptech · Barcelona, Spain
Barcelona-based Qilimanjaro Quantum Tech has completed a €19.6m first close of its Series A to industrialise its quantum computers and develop new chip generations. The company says Indra Group invested €10m through IndraMind and Spain’s Society for Technological Transformation (SETT) committed €9.6m. Qilimanjaro expects a further close in the fourth quarter with Avançsa and existing investors.
Founded in 2019, Qilimanjaro builds the full computing stack: superconducting fluxonium chips, control electronics, cryogenics, software and algorithms. Its systems combine analog and digital quantum processors with high-performance classical computing, offered as on-premise installations, cloud access and adoption services.
Funding moves the challenge from demonstration to production
The company reports that eight systems have been deployed and that three operate inside the Barcelona Supercomputing Center, including an analog quantum computer integrated with a European high-performance computing centre. It works with customers in energy, telecommunications, logistics, healthcare and finance, and employs 80 people from more than 22 nationalities.
The new capital is intended to expand manufacturing and deployment capacity, rather than finance a single laboratory milestone. That distinction matters because quantum companies must make tightly coupled hardware, calibration and software reliable outside their own research environment. Qilimanjaro’s full-stack approach gives it control over those interfaces, but also leaves it responsible for industrialising each layer.
Industrial and sovereign capital arrive together
Indra brings a potential route into defence, security and industrial workloads, while SETT’s renewed backing frames the company as strategic Spanish infrastructure. Qilimanjaro CEO Marta P. Estarellas describes the pairing as sovereign and industrial capital working together to keep quantum capability in Spain.
The commercial test is now deployment quality. More machines and chip generations can broaden access, but customers will still require evidence that hybrid quantum systems improve specific optimisation, simulation or AI workloads relative to classical alternatives. The next close may enlarge the round; this brief records only the €19.6m first close already completed.
