Douglas (Doug) Levin is an American businessman, technologist, and serial entrepreneur. He is best known as the sole founder and first CEO of Black Duck Software. Levin saw early on that developers’ use of open source code in commercial products created code management and license compliance concerns among enterprises. In addition, he was one of the first to recognize the application security risks associated with open source software. He started and built Black Duck to address those issues. Today, the company’s products are the de facto standard for open source software security, software development and management – a mandatory check box for most app dev projects and software.Levin founded or co-founded six other companies, and holds four software patents.
