I've been to a dozen accelerators and many teams were above 30/40 years old and some with kids. So definitely not late for you but it will take a lot of time, grinding, resources, and its an emotional rollercoaster! First step is to get some MVP going on and some basic business model and then apply to all the things. Good luck!
