We have a very small development team. But at the same time had big concerns about application quality. QA doesn't have to have a size. With Sauce we were able to setup some simple test automation in a day, and can grow in steps towards full automation. It kept our cloud infrastructure cost down so we did not need to scale compute instances to manage a grid. And we did not need to find a testing team, which we would have outsourced. The benefit we did not prepare for is how it fit into our CI process. Their new functionality allows us to kick off tests from GitHub and when things pass do a build. They have better analytics now as well, just wish I could get more via the API. We are big fans.
