Simply put, an engine is a machine for converting energy (fuel) into motion. And an engineer is a person who designs, operates and oversees an engine. Most business owners start out expect to be all three: fuel, engine & engineer for their startup. We bootstrap, use sweat equity, and “build the plane as we fly it” all in the hopes that little by little we find other sources of fuel to create motion within our business and build a sturdy engine to generate the profit & lifestyle we envision. We start generating cash, hiring a team, sourcing vendors, creating structure, investing in capital, etc.
