In many contexts, "turn around" is used for cases when you "transform" something completely. E.g. "He turned around his life." I want a synonym for "turn around" in such contexts, but something which is stronger than "transform". Here is the sentence for which I need the synonym:
This prospect turned out to be a key element that turned around our business.
Now, here "turn out" and "turn around" are giving a repetitive sound. Hence, I am looking for a synonym for "turn around".
Or else, if someone can suggest some other changes to this sentence, which would make the sentence more lively, please do so.
