My co-founders and I set up an equity split with a mix of vesting and role based compensation. It was finalized last year, and everyone signed off on it. One of my co-founders is now wanting to increase their equity share on the argument that our respective roles are now not exactly what they were when the distribution happened.
Any thoughts on how to handle it and convey that the split is not a living document that can be constantly updated (risks are not at all the same?).
