Despite the data quality issues, there are a number of companies that license CrunchBase's data and have built their own subscription services on top of it. One such company has a few hundred thousands of dollars a month in revenue and has raised millions of dollars in funding. While most of the CrunchBase "repackagers" will tell you they add proprietary data, from what I have seen, most rely very heavily on the CrunchBase data and without it, would not have commercially viable services.
