I'm not an expert - just learning more about this myself over the last few months, but it sounds to me like the investment style you're talking about exists inside the world of private equity.
They're not playing the venture game - it's a different model. Buy and hold for either cashflow/dividends, or do some financial/managerial engineering and flip the asset.
Outside of the world of Venture Capital, there's a HUGE spectrum of investors out there doing every kind of investment - just gotta tune into it I've found.
(Great place to start is a podcast called PE Funcast - seems to me they've been doing this type of investing.)
Say A round wanted 100x. B round 10X. C round 7x. D round 5x. That will bring the total expected return to around 8B. However I am sure C and D would not mind a 3X or 2X, while B would probably settled happily for a 5X.
