CubeCab submits DOE STTR Phase II application
50 FOMOCubeCab submitted a Phase II application under the Department of Energy's STTR program. This follows earlier public comments about waiting for the Phase II NOFO and working on the proposal through summer and early fall 2026. The effort appears tied to the company's nuclear thermal launch vehicle research.
Why it matters
A Phase II award would provide meaningful non-dilutive capital for a tiny team; outcome remains pending as of late October 2026.
