You’re going to have 100 things you disagree about in the first year, and you need to be able to talk those through without it being a world war. If he can do that, despite how he is around politics, then he at least checks one box. If you’re not unified in the type of culture you want to build, that will be debt you have to pay down in the future. Might not bite you till an A round, but will matter some day if successful. If they’re a straight up liability, which he sounds like he might be, you may end up having a cofounder leave early with a huge chunk of equity, which is always less than ideal. If you can limit his equity stake or increase the vesting cycle you may need to look into that. Happy to talk more one on one. Email is in my profile. Best of luck.
