I'm the technical co-founder and my co-founder non-technical; he's brought in so many soft skills around process, finance, sales, recruiting, etc.. that I would have (and would still) struggle at to replace.
He's also a domain expert in our field so for me it was definitely the right choice to make.
he doesn't sound nontechnical if he's a domain expert in your field, but presumably he would be even better if he also had whatever technical skills you're saying he lacks, not worse
