Yup. I came here to write this. You don't know about how those people helped because they're not the public face of the company; but often they started the seed of something that grew into something big (like you!) or solved some critical technical problem blocking scale, or helped land a key deal, or any of a hundred factors that, if they weren't done, would have severely hit the growth of the company, and couldn't have been easily done by someone else walking in off the street with a nice CV - things that required history with the company, its codebase or market or customers etc.
