We use Gigalixir to host our consulting company's website. We deprecated our Squarespace website inside of a week with minimal knowledge of Phoenix deployments, something we wouldn't have seriously tried without Gigalixir. It absolutely slaps being able to hack something out locally and have it in production sixty seconds later, without having to engineer a deployment pipeline. (Which, don't get me wrong, we can do, but the time cost would quickly exceed the value of just trying stuff out.)
