How much money to start a VC?

I'm curious, just how much money does one need to start a venture capital (VC) fund? I understand that it's a significant investment, but I'm trying to get a better grasp on the financial requirements. Is there a specific threshold that's generally considered the minimum, or does it vary greatly depending on the fund's strategy and target market? Additionally, are there any other key factors, aside from the initial capital, that a potential VC fund founder should take into account when embarking on this endeavor?
