Cambridge-based tech startup Silicon Microgravity (SMG) has raised $8.1 million in a funding round led by West Hill Capital with participation from the UK Innovation & Science Seed Fund (UKI2S), aiming to scale its GPS-free inertial navigation and gravity sensing technologies. Originally a spin-out from Cambridge University backed by BP, the company utilizes advanced microelectromechanical systems (MEMS) developed by Professor Ashwin Seshia to provide highly accurate, compact, and low-cost navigation alternatives in extreme environments where GPS signals are unavailable or denied. Operating across dual-use commercial, space, and defense sectors, SMG’s high-performance accelerometers, gyroscopes, and gravimeters are currently supporting advanced space programs—ranging from lunar exploration to satellite-enabled mineral surveying—and the startup plans to use the capital to scale its UK manufacturing, expand semiconductor production capacity, and accelerate commercial partnerships across Europe and the United States.

Business Owners: Earn Unlimited Cash Back and a $1000 Welcome Bonus

Every month you put business expenses on a card with no cash back, that's money left on the table. This card flips that script — apply and if you get approved, hit a spending threshold within the set timeframe, and earn a $1000 welcome bonus on top of unlimited cash back on everything you buy, no caps, no categories to track. Throw in a $0 annual fee and free cards for your employees, and it's one less thing costing you money without you realizing it. FinanceBuzz experts pointed this one out for exactly that reason.
