## Summary

California aerospace company developing Duality electric adaptive engine for supersonic trans-Pacific flight; $27.1M raised in 2025 from a16z, Lowercarbon, and United Airlines Ventures as YC W24 company.

## Company Overview

Astro Mechanica is a Sebastopol, California-based aerospace company developing the Duality — an electric adaptive engine for supersonic commercial aviation — targeting viable trans-Pacific supersonic flight at commercially sustainable operating costs. Founded in 2020 and backed by Y Combinator (W24) with $27.6 million total raised including a $27.1 million round in April 2025 co-led by Andreessen Horowitz, Lowercarbon Capital, Giant Step, United Airlines Ventures, and Neo, Astro Mechanica's 23-person team aims to demonstrate trans-Pacific supersonic flight within three years.

The Duality engine's electric adaptive architecture addresses the economic challenge that ended Concorde and constrains modern supersonic programs: conventional turbines operate efficiently only within a narrow speed/altitude band, running inefficiently at takeoff and subsonic cruise. Duality's adaptive capability adjusts engine parameters dynamically across the full flight envelope — takeoff thrust, subsonic cruise efficiency, and supersonic transit — potentially achieving fuel economics that make supersonic routes viable beyond ultra-premium first class. The electric component enables energy recovery and more precise engine modulation than purely mechanical throttle systems.

In 2025, Astro Mechanica competes in the supersonic aviation propulsion market with Boom Supersonic (Overture airliner, $700M+ raised, United Airlines purchase commitment), Spike Aerospace, and next-generation propulsion programs at GE Aerospace (NYSE: GE) and Pratt & Whitney (RTX) for the emerging supersonic commercial aviation market. United Airlines Ventures' investment creates a direct airline customer pathway. Lowercarbon Capital's involvement reflects the clean supersonic propulsion thesis. The 2025 strategy focuses on the trans-Pacific demonstration milestone that would unlock the commercial partnerships needed for certification, building the regulatory relationships with FAA and ICAO for supersonic noise and emissions standards, and attracting aerospace propulsion engineering talent to the Sebastopol team.
