From the inside · Glassdoor reviews, 2022–24
Engineers on Glassdoor praised the satellites but not the paycheck: reviewers said equity-heavy pay packages lost much of their value as the shares fell, and a return-to-office mandate — which employees said leadership tied to weak results — strained morale.

How it happened
Spire Global operates a constellation of small satellites collecting weather, maritime and aviation data. It went public via SPAC in August 2021 at roughly a $1.6B valuation. Post-SPAC, its stock declined heavily amid cash concerns and the space-sector slump, dropping its market cap below $1B and to ~$0.3B by 2026, a ~81% decline from peak.
