“My co-founder is ruining my business…”

That is something I have heard countless times in the startup world. Too many founders pick their core contributors like they are swiping on dating apps.

Shared interests? Check.

Good vibes? Check.

Actually tested each other under pressure? Nah, we will figure it out.

The co-founders who survive are battle-tested allies.

Here is what separates the good partnerships from the bad ones.

Foundations of Strong Co-Founder Relationships

Some things you should know:

Brutal honesty: If your idea sucks, they tell you.

Complementary skills: You are not clones. You are puzzle pieces that fit.

Shared hunger: You are collectively putting in the hours to build and grow.

Ego check at the door: Your company comes first, always.

Crisis-proof communication: You can disagree with clients, employees, or each other and still choose a solution together.

Conclusion

Building a startup is hard enough. A weak partnership will break you.

A personal note to my co-pilot, Devin Ambron.

Thank you to Devin Ambron for being an awesome co-pilot at Market Chemistry with me.

I firmly believe our work together is an example of a top-tier partnership. Bringing you on as my business partner has meant doubling my creative power, problem-solving skills, and relationships, plus a whole suite of unique knowledge.

You have got the sauce (from one Italian to another).
