Matryoshka doll, originating from Russia is a set of wooden dolls of decreasing size placed one inside another.
Much like having dolls placed inside each other, organizations that thrive at scale are usually set up in the same way.
Like Elon Musk has recently said that Tesla is really a bunch of start-ups operating as one.
Corporate bureaucracy, long chains of command, and long decision-making circles ultimately become the death of most big corps but those who are set up as one organism with a bunch of mini start-ups thrive because of the freedom to make decisions and cut out the unnecessary middlemen.
