Five years ago, I joined a tiny startup that was promising to democratize integration (Talend). Coming from another data integration vendor – a proprietary one – I liked that I would be able to leverage my market expertise. But, like most people at the time, I knew nothing about open source. Of course, I had heard about Linux, I had a vague idea of what MySQL was, but that was the extent of my open source expertise. The two founders of Talend told me not to worry, that open source was only in its infancy, and that we would be part of building it.
