Greenjets

Greenjets is a London-based company engineering the next generation of electric propulsion systems for the advanced air mobility market. Founded in 2021 by CEO Anmol Manohar and CTO Guido Monterzino, the company officially spun out of Blue Bear Systems Research in late 2022 following a research project called Project InCEPTion. The founders bring extensive aerospace and engineering experience; Manohar previously worked on future aircraft platforms at Rolls-Royce, while Monterzino has a background leading engine teams at BAE Systems and Cosworth. This deep domain expertise is central to the company's approach.

The company's primary business involves the design and manufacture of ducted fan electric engines for a client base of airframe manufacturers across North America and Europe. It operates in both the commercial and military drone sectors, aiming for a balanced presence in each. Greenjets' business model focuses on providing 'propulsion as a service,' which includes offering bespoke engine development to meet specific customer requirements for weight and thrust, a key differentiator from competitors that only offer off-the-shelf products. The firm generates revenue through the sale of its propulsion systems and has secured significant funding, including a $7 million Pre-Series A round in March 2025, to scale its manufacturing capabilities.

Greenjets has developed a range of patented electric propulsion systems, noted for being significantly quieter and more efficient than traditional open-bladed propellers. Its ducted architecture not only enhances safety by shielding the blades but also reduces noise levels by up to 93% and power consumption by up to 45% for a given thrust. The product lineup includes engine families like the Sycamore, Aspen, and Hemlock, designed for various aircraft from small drones to larger multirotor and commuter aircraft. The company's focus on psychoacoustics—the perceived 'annoyance' of sound—is a critical benefit for drones operating in populated urban areas. By addressing key challenges of noise and efficiency, Greenjets aims to accelerate the adoption of sustainable aviation.
