> I do not agree that in corporate you make lesser impact. Big company usually produces things used by real people.

It really depends on what kind of impact one is looking for. The author touched on this point but think he could have made it clearer that working at a startup gives you the possibility of having a significant impact on a product with limited reach while working at a larger company gives the possibility of having a smaller impact on a product with much greater reach.

This is not always the case of course, you could work at a startup that creates an extremely popular product (though it may not be considered a "startup" for very long then) or work for a corporation on a project that will never see the light of day.
