It's entirely possible I don't know what I'm missing and/or my React usage so far mostly falls in the "toy" scale, but I've not yet felt a need for Redux or another state management system. Our strategy so far involves very little use of component state (nearly all usage is for form fields and showing/hiding modals). Everything else is in the props, and all 'app state' lives in a collection of modules that get DI'd into the components via their props. It seems like it's probably not too far from what Redux is going for at a conceptual level, but so far it's worked well and been easy to work with.

We also use TypeScript though, so this more OO-style approach felt more natural. It's not particularly verbose (in the context of interfaces and static types, so YMMV) and it's been extremely easy to work with so far.
