Tesseract Space Inc is an alumnus of Y Combinator the pre-eminent start-up accelerator - Tesseract builds satellite propulsion systems that use non toxic propellants, have dramatically better performance, and lower cost than existing options. Current satellite propulsion technologies rely on toxic fuel that is dangerous to handle. This results in very hgih fuelling costs of up per satellite and are cost prohibitive for inexpensive smallsats. Tesseract has redesigned thrusters for low toxicity fuels and modern manufacturing techniques such as 3D printing. This eliminates the $500k fuelling cost and provides twice the propulsion for half the price.
