I see the hero as the one pushing innovative new strategies for world-changing (eg. starting a business in that area, like Givewell—specifics subject to what changes the hero wants to make), while the sidekicks are the ones that help out by being employed in that business (in a non-directing role) or donating to it or providing moral support etc. - they help what’s already been created do better, and thus have to choose from people/causes that already exist rather than creating their own.

What would examples of new such strategies and businesses be?
