Silicon Microgravity Limited (SMG), the UK advanced semiconductor company pioneering next-generation MEMS technologies, has secured £6 million in funding to accelerate commercial growth across the defence, space and semiconductor sectors.
The round includes investment from the UK Innovation & Science Seed Fund (UKI2S), managed by Future Planet Capital, with participation from both the UKI2S Defence & Security and Space portfolios, alongside lead investor West Hill Capital.
The investment marks UKI2S’s first participation in SMG through its Space Portfolio, building on the company’s existing relationship with the fund’s Defence & Security portfolio, and comes as SMG achieves growing commercial traction with a number of globally recognised customers.
SMG’s proprietary technology enables the production of high performance microelectromechanical systems (MEMS) devices designed for extreme operating environments. These technologies are increasingly critical for modern defence systems, satellite communications, navigation, sensing and autonomous operations.
The company’s MEMS accelerometers are already supporting advanced space programmes, with applications spanning launch vehicles, lunar and planetary exploration, satellite enabled critical mineral exploration alongside wider dual-use commercial and sovereign capability deployments.
The funding will support SMG’s continued scale-up of UK manufacturing capability, expansion of its engineering and semiconductor production capacity, and acceleration of commercial partnerships across Europe and the US.
As global demand intensifies for resilient, sovereign semiconductor supply chains and dual-use technologies, SMG is positioning itself as a strategically important UK player operating at the intersection of advanced manufacturing, defence and space infrastructure.
