In Shoshanna Solomon's article (in French) for the Times of Israel about how founders of startups need to let go, she discusses how change affects management style. Among others, she quotes Eyal Waldman of Mellanox as saying "...when the company was a start-up, I was much more involved in all the processes. I miss that. I used to be more involved. Now I need to talk a lot. It is more difficult to play on the playground of adults, because if you fail, the fall is stronger and more difficult. "
