Investors don't give two hoots how many hours your people work, they care if you reach the goals you promise you will (which translates near directly into likelihood that their investment has some return). The key insight is that working more hours doesn't lead to more work being accomplished, because there's a saturation region to productivity. Couple that with the fact that there's a negative return for sustained overexertion, consistently working excessive hours actually is less productive for individuals and teams. But if you don't believe it, measure it.
