Momentus

How it happened

Momentus was a U.S. space-infrastructure company offering in-space transportation that went public via SPAC in 2021 at about a $1.2B valuation. National-security scrutiny, leadership changes, and operational setbacks gutted its market value, leaving it a sub-$50M micro-cap, down roughly 96% from peak. Glassdoor reviews traced the decline from inside: staff prized the engineers but said the culture flipped from beloved startup to toxic once a bench of ex-military and former old-guard aerospace and government executives took over. Insiders recounted promised raises deferred even as the health plan was downgraded, repeated layoff rounds and relentless turnover, and punishing hours — several bracing for the worst long before the stock cratered.
