Most founders source their first customers in ways that don't scale. When they hire a CRO or CMO, they discover that they don't understand who their best customers are. These new hires don't fare much better: they use the data they have, such as industry and number of employees, instead of searching for the data they need.
If you can't understand your customers, you can't build on that foundation to grow. Raising a lot of money can hide the problem for awhile, but ultimately you'll need to understand your customers deeply to maintain product market fit and scale.
