Everyone tells you that you need to start with a niche, a beachhead market, and then grow from there. But how does that actually work? What does that really look like? It looks like Mark's story starting and growing GoBolt.  Mark started off storing items for students over the summer. He expanded to storing all things for all people. He now provides logistics for enterprises. He's raised over $150M and has over 1,000 employees. But it wasn't pre-destined, it was 100% organic.  What really matters is finding a problem that you're acutely positioned to solve and then solving that problem. If you have real demand, and you stay close to your customers, things tend to take care of themselves.
