Documented cause
Exos Aerospace, led by CEO John Quinn, developed reusable suborbital rockets targeting payload testing markets. After several delayed launches and a crash landing of their SARGE rocket in September 2020, the company failed to convert suborbital demonstration flights into paying contracts. By 2022, funding dried up entirely as investors pivoted to orbital-capable companies. The company quietly ceased operations having spent approximately $10M in total raised capital.
Lesson
“Suborbital demonstration flights must convert to contracts within 18 months or the market window closes permanently.”
