Ask HN: I am doing $2M annually as a solopreneur and need your help 10 years ago
Seeing from your earlier post about a year ago when you seemed to be dealing with a burnout, I would recommend getting a co-founder or someone experienced who can guide you.
Handing out some responsibilities is not bad, it's what happens when you grow. It will help you to scale and grow more easily with less stress.
Good luck!
