Jenkins is a 15-year-old mature open-source CI/CD project that I created, and it really dominated the market, and CloudBees is a 10-year-old business that I served as CTO, and it has been in a symbiotic relationship with Jenkins. In this talk, I’d like to look back at the history and share what worked and what didn’t work, such as the difficulty of justifying engineering efforts to OSS, how enterprise product can stifle open-source, and the impact and the consequences of hiring people from the community.
