Lived in Silicon Valley for a time, and actually met one of the VC guys. You guys got the essence of VCs. They listen to a number of entrepreneurs, pitch their idea of the 'next best thing', and from that, decide whether to commit capital to bring that product from conceptual to actual. VCs fund this process, and keep an eye on how well they progress. Other than money, most of the VCs are experienced businessmen/managers, and since they have skin in the game, can and do, offer 'suggestions' to the originator. Kinda like Shark Tank, only bigger. Usually, along the way, more funding is needed, called mezzanine financing, which means more capital infused, to actually produce a product, or ramp up production to take to market. All of this chips away at the founder's (and his co-founder's) equity position. To skip ahead, when the company is sold to another company, then the founder and VC's cash in on their 'Founder's Stock', usually issued at pennies a share, to cash, or shares in the acquiring company to recover/make their profit. The Private Equity (or Investment Banker) slice, is exactly what was mentioned. This is where the 'Corporate Raiders' or such step in. Companies find themselves in need of money, and really sell themselves to an acquirer, or maybe get into a situation where someone starts buying (usually at a discount) their shares. Then, (am skipping some parts) the company is dismantled by shedding the pieces/divisions/non-viable groups to other companies, keeping the core group intact. Has been called many things over the years, such as 'right sizing', downsizing. Essence is that the Sum of the parts is greater than the whole. KKR/rupert Murdoch, and others have made headlines over the years. Some sell everything, taking their profits, and others may keep the crown jewel, and run that alone. Excuse the rant, and excuse some of the above that some may take issue with, but what I remember from my MBA days. PS, my cousin had worked for at least seven of these 'start-ups', and earned a good but not great living (ultimate payout was a large number of founders shares). Have lost touch, but hope he hit it big.
