Pure Entertainment Company (PEC) was an early entertainment and live-event setup company. It provided sound, lighting, and entertainment setup for real events.
What matters about it in the venture map is the operating reality it forced early: client service, logistics, equipment management, setup/teardown, and delivering live experiences where failure is immediate and public. That constraint pattern shows up again later in much larger systems work: you can only move as fast as your prep, interfaces, and reliability allow.
