Documented cause
XCOR Aerospace was founded in Mojave by ex-Rotary Rocket engineers to build highly reusable, low-cost rocket engines and a suborbital spaceplane (Lynx). They raised ~$40M from private investors and developed genuine technical innovations in reusable propulsion. For 17 years they made progress — but hardware development is exponentially more expensive than software, and XCOR was perpetually underfunded relative to the development timelines required. When investors grew impatient and their Lynx program faced further delays, XCOR filed for Chapter 11 in September 2017.
Lesson
“Reusable rocket development requires either government contracts or billionaire capital. Private VC rounds cannot bridge 17-year development timelines.”
