The company has flight-tested prototypes on Dornier 228 and plans a Dash 8-400 testbed, with certification applications underway with CAA and FAA. It has partnerships with major OEMs and nearly 2,000 engine pre-orders from global airlines, representing over $10bn in future revenue potential. On September 12, 2024, ZeroAvia completed its Series C financing round at $150 million total, co-led by Airbus, NEOM Investment Fund, and Barclays Sustainable Impact Capital (noted as Sustainable Impact Capital in some reports), with Scottish National Investment Bank contributing £20m (~$26m). Additional investors included UK Infrastructure Bank as cornerstone, American Airlines, IAG, ITOCHU, and existing backers like Breakthrough Energy Ventures, Horizons Ventures, Ecosystem Integrity Fund, Summa Equity, Alaska Airlines, Amazon’s Climate Pledge Fund, and AP Ventures.
