We use git to manage the codebase of two apps that have about 15 people working on each. Every team or project branches from master at the start of an iteration and works off that branch until the end of the iteration then merges/rebases back onto the master branch. Then we we tag and branch at the end of an iteration to push code live. Works very well for us and seems a lot less painful than the frontend guys using SVN.
