Where does data quality need the most attention in today's business?

Hi, I am Martin, enthusiastic product manager - trying to launch a product that will solve the problem of data quality. We are building collaborative data quality solutions that will support teams with managing their data. Dirty data in, clean data out. That's our goal. In order to start successfully, we'll have to focus on a single problem first and try to find a good market fit. Where do you think we have more chances to score first?
