When you and your cofounder are not a match, but you have shares in your registered company.

Hello Everyone, My name is Prince, and I am a product designer and aspiring indie hacker. Over the years, I've made the error of registering my company before gaining traction or even launching it. One recent difficulty occurred when I brought on a co-founder and paid my hard-earned money to register the company one stripe atlas, but we were unable to start since my co-founder (CTO) had other priorities.
I saw on Atlas that you need to call a lawyer to address this by reclaiming the shares. As I write this, I'm currently reading through it. One solution to this challenge that came to mind was to have a way to verbally and contractually agree on shares without necessarily registering the company.

I'm considering developing a system in which two people collaborate on a project for a set period of time before registering. Of course, this can be remedied by bringing money for the business registration without committing to it all at once.

I'm not sure if this is a problem worth tackling or if folks who can't develop face the same issue. This is my first post or comment on this site, so any input is appreciated.
