It's hardly a secret that most people working on/for Matrix are employed by Element.

https://matrix.org/about/ has a list of names for the "guardians" of the foundation (whatever that may mean exactly) which consist of 40% Element, 60% external parties. The core spec team at the bottom links to Github profiles, from which I believe 8 out of 10 people work for Element (though I'm not 100% sure if the last person in the list still works for them based on his Github profile tag).

Thib isn't part of the foundation, he's just part of the business side, and quite a public part at that. I think his role is a good example of the distinction between Matrix and Element.
