Oxford Engineering Science spinout Densix launches with $4 million seed funding

Densix is based on more than six years of research developed within the department and is creating a new class of ultra-dense power converters designed to significantly reduce system size while improving energy efficiency, thermal management and reliability.

The company says its proprietary technology can enable up to an eightfold reduction in form factor compared with conventional systems, with applications in AI data centres and future power grids.

The funding round was led by Oxford Science Enterprises, with participation from Parkwalk Advisors and the University of Oxford Innovation Fund.

Densix was co-founded by Dan Rogers (CSO), alongside Anders Hakfelt (CEO), Aleks Ristic-Smith and Kawsar Ali. 

Anders Hakfelt said: “Densix reflects the strength of Oxford’s deep-tech ecosystem — where world-leading research, venture building expertise and early-stage investment come together to build companies with global potential.”

The company was supported by Oxford University Innovation through its Venture Scouts programme, which helps connect founders with scientific teams to translate breakthrough research into commercial ventures.

Prof Rogers said: The interdisciplinary nature of the department has been key in developing the technology that has led to Densix's spinout. Oxford undergraduates, postgraduates and research staff in the department have all been involved in one way or another in developing aspects of Densix's technology. The department has also been highly supportive in helping establish Densix and enabling close collaboration between the company and ongoing academic research.”

The technology underpinning Densix was developed within the department and is licensed through Oxford University Innovation. The new funding will support the continued development and scaling of the company’s technology platform as Densix expands its engineering and commercial activities.
