Particularly CI. If you want to be able to release fast and often, having that automated is going to save you a lot of time.
And CI doesn't immediately have to include everything you'll eventually want; just having automated build and deploy will make your life a lot easier. Add some automated testing as soon as you can afford to (which hopefully is right away, because it's not that hard to set up), and you're ready to move.
