## Summary

Electric aircraft aerodynamic flow control technology increasing range and payload 30%; Australian government-backed with clean-sheet design flight planned for 2025 competing in e-aviation.

## Company Overview

Seaflight Technologies is an aerospace engineering company developing advanced aerodynamic flow control technology for electric aircraft — using active flow control systems that manipulate airflow over wings and control surfaces to increase lift and reduce drag, enabling electric aircraft to carry 30% more range or payload than they could with conventional aerodynamics. Founded in 2022 in Carson, California and backed by Y Combinator S22, 7 Percent Ventures, and Collaborative Fund with $3.68 million raised, plus $2 million from the Australian Government's Electric Aviation Technology Program (EATP).\n\nSeaflight's active flow control technology uses carefully placed airflow actuators (blowing or suction devices embedded in the wing surface) to prevent boundary layer separation and maintain laminar flow at higher angles of attack — effectively giving the aircraft a larger effective wing area without the weight and drag of a physically larger wing. For electric aircraft where battery energy density is the primary range constraint, a 30% improvement in aerodynamic efficiency translates directly to 30% more range or payload without adding weight. The clean-sheet aircraft design planned for 2025 demonstrates the technology at full scale.\n\nIn 2025, Seaflight operates in the electric aviation technology market competing with Joby Aviation, Wisk, and Archer Aviation for electric air mobility technology, and with Boeing and Airbus research programs for advanced aerodynamics in commercial aviation. The Australian government EATP funding reflects the country's significant interest in electric aviation for its geographically dispersed population and domestic air travel market. Seaflight plans a full-scale demonstrator over Australia in early 2026 that would validate the technology at commercial-aircraft scale. The 2025 strategy focuses on completing the clean-sheet design flight test, building the flight test evidence needed for partnership discussions with airframe manufacturers, and positioning for the regulatory framework that governs commercial electric aircraft certification.
