One big, big name is Youtube, who was burning through other people's money faster than a drunk Kennedy and getting rightfully sued every 5 minutes for copyright infringement. They had a cool idea, and a completely non-sustainable business model that was guaranteed to put them belly-up within 36 months until Google bought them. Google brought to bear their expertise in funding a free service in a way that keeps customers happy (aka the best targeted advertising available) , allowing YouTube to survive and thrive rather than burning away investors' money until investors got sick of it and'the whole thing imploded.
YouTube's business model from the beginning was to get bought by Google, and so they focused their business towards that end and succeeded. Had that not been their primary goal, they may have done things very differently. In any event, using them as an example of a smaller company that needed to be bought isn't wrong, but the assertion that they needed the good processes that came from the larger company is false. They were very efficient at exiting for maximum return for their shareholders.
