I was a solo founder and at the end of my journey, I realized I would have given up 25-50% of my company just to 1. have someone else to talk to on a daily basis 2. have someone I could bounce ideas off, 3. someone who could have focused on the parts where I was bad (even if they didn't have that skillset).
I would have done twice as much as solo founder.
Push yourself to find a co=founder. Invest 10% of your time in it. Have no expectations. Slowly you'll get a nose for the kind of people you will want to work with. Also you'll polish up your people skills which you'll need to raise money and to run a sucessful business in the future.
If you want to go fast, go alone. If you want to go further go with a team. (There is no fast startup.)
