Josh Koenig

When a developer tells Josh Koenig how happy they are, that the drudge work has been automated and now they can handle more and larger projects, he knows it’s only a matter of time. Open source just took one step closer to world (or at least world-wide-web) domination. As Co-Founder and Head of Developer Experience, Josh believes the clues to Pantheon’s destiny are in its developer DNA: best practices, modular architecture, high performance are key for all websites whether it’s a personal hobby project or a major enterprise launch. And Josh believes all this should be easy and fast. Developers need tools that let them tackle more and bigger projects with less stress and worry, and that’s what he works on As a very early Drupal adopter (user #3313), Josh was part of the team that drove the first high-profile public Drupal use-case with the Howard Dean campaign in 2003. He went on to found the Drupal Dojo, an online learning community for developers, and to co-found the premiere Drupal agency in San Francisco, Chapter Three. Demand for open source website technology is high and getting higher, but the the lack of readily available services presented too many challenges for widespread adoption. Developers and organizations didn’t need big support contracts to build faster, more scalable websites — they needed better tools to do it themselves. Today, Josh lives for the spark in a developer’s eye when they realize “there’s a best practice for that,” and it’s already built into Pantheon, the professional website platform.
