What frameworks would you use to handle such an steep growth curve? Most startups I know of start of with rails or the like - and obviously they couldn't handle the strain. So what would you use?

WhatsApp was a pretty well known case for Erlang[1], given that I'd think Phoenix would be a great fit.

Phoenix will be much better than Rails out of the box for things that need a certain level of concurrency. However Twitter's problems were about scaling dependent writes, this is a data-store / architecture problem that really has nothing to do with the chosen language.
