I have been using this solution for two and a half years. I was serving as vice president of engineering and integration in a company in Austin, Texas. I was assigned to acquisitions of companies, more specifically to the technical due diligence that takes place during acquisition. So, we used Black Duck Hub very extensively. We had the biggest ever contract with Synopsys for almost $1 million per year, and we used Black Duck Hub to scan the license for each acquired company. We had a very aggressive acquisition plan of almost one acquisition every 15 days. So, I have accumulated quite a big experience with the Black Duck Hub tool.
