From experience, if you start creating changes in departments to have a better PMF and a clear GTM strategy, you should shift to a hybrid base + commission and ask for a clear mandate if you believe you really can make a change, this was a game changer for me with my current client, once I delivered a lot of value across multiple departments and I pushed my ideas for change, I switched to the hybrid approach with clear executive power and mandate, then I could easily double down and lock in
