Investment thesis
Nebular focuses on very early and unexpected opportunities, backing uncommon people, ideas, and technologies where new markets and movements are beginning to form. The firm positions itself as an early-stage lead investor that moves fast and writes lead checks, while remaining hands-off with founders unless support is needed. It embraces founders who chart new paths and claim unmarked territory, favoring rebellious, unconventional bets over obvious, established plays.
