Keeping startup costs close to zero means spending only when there is a clear return. Initial costs should directly support sales, provision or learning from actual customers. Service- or knowledge-based businesses work best because they require low upfront costs and can sell quickly without inventory or heavy infrastructure.
You can still build a successful, scalable business without high-profile investors. In fact, doing so often allows for greater long-term control and strategic clarity. The best business opportunities are hiding in your backyard. Real disruption often lies in solving everyday problems in industries that are overlooked by investors focused on trendier sectors. More money sometimes does mean more problems. Taking money means giving up some control to investors who may lack your industry knowledge, which can be challenging.
Cuban's origins are fairly humble. He was raised in a middle-class family in Pittsburgh and once had a job selling garbage bags door-to-door around his neighborhood (yes, you read that correctly). He bootstrapped his way up, starting with bartending and software sales before founding MicroSolutions, which he sold for $6 million in 1990, and later co-founding Broadcast.com, acquired by Yahoo for $5.7 billion in stock during the dot-com boom.
