Funding history includes a seed round led by Khosla Ventures, Series A and B rounds totaling over $116M by 2022 across multiple rounds, and a reported $100M Series B in May 2024 at $1B valuation led by Bling Capital, Sam Altman, and Khosla Ventures.

Lessons from these platforms will inform the commercial passenger aircraft Halcyon. The investment underscores private capital's role in advancing hypersonic technology alongside government early markets. CEO AJ Piplica highlighted the round as validation of the team's execution amid high engineering challenges, entering a phase with elevated stakes and resources for ambitious goals.
