Deep insight: This tool isn’t just reactive; it’s proactive. By cross-referencing names early, entrepreneurs avoid the “name squatter” trap, where similar entities block your branding. For instance, if you’re eyeing “GraniteTech Solutions,” a quick scan might reveal a dormant but reserved name, prompting a pivot before you invest in logos or domains.
