Take for example, Google:
As I understand, the search engine was started as a research project.
(by the way, was it patented or the code is fully open through the contents of the respective thesis work?)
But during all consecutive successes (initial investors, IPO, growth) - how did the founders manage to keep the main technology in their hands?
They hired a lot of new engineers to work on the core technology, while they did a lot of other non-technical stuff themselves (business relations, investments, marketing, etc.).
Taking that into account, there is some probability that now the founders and initial developers of the main Google's technology are:
vaguely understand how the current version of the core system works (because they are not just the developers now);
have employees that have more control over the core system's technology than the founders have.
Is that true?
If it is true, isn't it dangerous for the founders to give up control in such way?
How can this be fixed?
