I don't know about entrepreneurship but investment is definitely struggling. As a share of GDP it is relatively low right now compared to the long run average (in the U.S). And that is in spite of exceptionally low interest rates. However, investment as used in GDP calculations comprises more than just business investment. It also includes construction of new homes for instance. So to compare investment to corporate profits, which are indeed relatively high, you would need to know the level of business investment and I don't know where to find that data right now.
