How should co-founders divide responsibility between themselves?

Kathryn Minshew · Sep 2, 2016

A co-founder should defer to their partner in the partner's area of strength even when they disagree

At the end of the day that person will be most effective at making the decision in their domain

Scope: applies to areas of clear divided expertise

Co-founders should split responsibility by 'majors and minors' across every part of the company rather than dividing the company into separate territories.

It lets each defer to the other's superior judgment in their domain — Brett on sales and systems design, Clay on operations, finance, legal and people — while both stay engaged in consequential decisions.

Equality between co-founders — in age, life stage, naivety, experience and wisdom, not just equity — is what makes a co-CEO partnership work.

Neither person can pull rank; you both walk in not knowing and have to figure it out together, and being at the same life stage (marriage, kids) means you can support each other through the same hard periods.

Co-CEOs should be roughly 60–80% overlapped: full overlap makes the second person pointless, zero overlap produces constant conflict, so you need shared context on goals plus distinct swim lanes.

You need enough shared middle ground to agree on goals, but also clear roles and responsibilities so each can just do their own thing.

9:46 Sixty to eighty percent overlap with distinct swim lanes is the right co ceo balance

Deadlocked partner disagreements should be settled by who believes in it more, with the partners trading wins over the long term rather than trying to keep it equal

Like friends alternating who pays for lunch, it doesn't need to come out even; over a long working relationship deferring to whoever cares most tends to work out well

Lovable is better served by having one consistent public face — himself — while his cofounder stays focused on building the product

It is much easier for people to relate to the company if they see and keep seeing one person

Cofounders should write and sign a short explicit contract on decision rights and areas of responsibility at the outset, which avoids a lot of later conflict

He and Luis moved from advisor-student to equals and he didn't fully trust the arrangement; writing down who decides what defused it, and most conflicts land in the first two years anyway

85:18 Explicit written decision rights contract at outset prevents conflict

Being customer-obsessed is the most important thing for a company, and a co-CEO structure gives you the superpower of spending twice as much time with customers.

Customer obsession is the most important thing a company can do and it requires an indefinite amount of time with customers; like a boutique coffee shop that beats Starbucks purely through the time it spends listening to customers and refining product

12:37 Co ceo structure doubles time available for customer obsession

A co-CEO structure between founders with diverging desires and visions generates tension that can destroy the partnership
