Your question will get lots of different answers, because you've phrased it in an ambiguous way, with no context. This suggests to me, that in your specific case, the answer is no.<p>For example, "company" could mean private or public. It could be 5 people or 150000 people.<p>"own" can refer to control, responsibilities, legislation, profit share, product direction, market fit, investment of cash, and more.<p>"team" might be everyone from the lead who's been there from the beginning, to the receptionist hired last week. Or some subset.<p>Context matters. The goal of ownership matters. Each context is different so there's no blanket answer. Hence my answer to your (incomplete) answer is no.<p>I post this reply, not to be a dick, but to point out that your question needs a lot more thought and clarity. From that I infer (perhaps incorrectly) that you are the team-member in this context, not an existing owner.<p>I think you have a valid, specific, question in there somewhere, but you need to narrow it down a bit. And perhaps also figure out if team ownership will actually solve the problem you are trying to solve.
