We went from deploying every 6 months with fingers crossed and hunting for db changes that someone forgot he had somewhere to deploy every 2 weeks just because of automated builds that said "this does not compile". There is insane amount value in CD to test environment and merging changes multiple times a day and then having that deploy promoted with one push of a button to acceptance/prod. Keep in mind we barely have code coverage above 5% and we did not had much tests starting. It starts to pay off as soon as you have more than 1 developer in the project. Though even with one person building something and setting up automated build and deploy to something there is a lot of value when someone else has to do the changes to a project. We have bunch of small projects with Jenkins and Team city set up. I can jump into a project that I never touched before, make a fix and I don't have to figure out how the hell I am supposed to make production version out of it or build it.
