I think there are some companies / missions / bosses, who can clearly identify goals and a concrete strategy to achieve them. This, plus some equity, can really help set people's incentives in the right direction such that people want to put in more time and effort.

On the other hand, a lot of companies don't offer either and seem to believe that simply rallying the masses to put in 20% more time (on average) will somehow lead to outsized gains.
