-Some awesome people worked on the Phippy and Friends demo. [Stella Lin]() brought the idea to [Brady Gaster](), who then got a **ton** of help from [Ralph Squillace]() and [Ahmed Sabbour](http://twitter.com/sabbour) to bring it to life and [Mathieu Benoit](http://github.com/mathieu-benoit) for his Azure DevOps build pipeline. As mentioned earlier, Phippy and Friends was originally inspired by a blog post written by [Matt](https://twitter.com/technosophos) [Butcher](http://technosophos.com/).
