Founders role as business scales? I will not promote

Hi all, I’m wondering what roles does the jack-of-all trades founders do after the company scales? We are in the process of raising and it’s going ok so we should be able to hire more technical people build out the scaling required etc but the thought occured to me what happens to my role? I started the business solo as I was passionate about my vision, my co-founder joined along the way and he’s way more experienced (founded and exited multiple times) and he deals a lot with strategy, marketing, presentation, network etc like he has a very top down way of looking at this while I have a more user focused way so we work well together. The business got a lot more traction after he joined. As we scale I expect him to step into the CEO role but then I’m not sure what I’ll be doing? Like I built the MVP, the coding and design etc but I’ll be the first to admit that I’m not the expert in any of them and we will hire people to redo these properly. I guess my strength is getting excited, building and iterating fast and being user focused but that seems to be more a product role? This is my first startup so I’m quite curious what is the usual trajectory for people like me.
