Senior🎓
Top SchoolFergus Noble is a seasoned deep-tech founder and CTO with 16 years of experience building hardware-software products from first principles, currently leading Circularity Fuels after co-founding and scaling Swift Navigation for over a decade. He helped create the Piksi RTK GPS receiver that brought centimeter-accurate positioning to robotics, UAVs and automotive markets and now advises Swift Navigation as a board member. Fergus blends hands-on embedded and systems engineering with product leadership—he's contributed to the open-source libopencm3 ARM Cortex-M project, adding STM32F2 support and DMA/USART improvements. His background in physics from the University of Cambridge informs a rigorous, experiment-driven approach to product architecture and algorithm design. He mentors early-stage technical founders and has consulted across biotech and aerospace, demonstrating an ability to translate deep technical work into commercial outcomes. Based in San Francisco, he combines low-level firmware chops with strategic GTM and team-building experience, often operating at the intersection of hardware, navigation, and control systems.
