Perhaps the OP would be happier again working for an organically grown startup (rather than a "well" funded one). In such companies "Real money is being made and lost" - and a lot more directly than in a huge company (with all its inefficiencies). What each employee does matters, and stupidity is punished.
As someone bootstrapping a company that has no chance of getting funded by doing consulting - and having started from next to nothing in savings + high living expenses inherited from salaried days - I couldn't agree more.
