Co-founder roles: how to divide responsibilities

Why clarify roles from day one?

In the very early days everyone does a bit of everything, and that is normal. But without a named owner for each topic, some tasks fall through the cracks while others get done twice.

Clear roles let you move faster, because everyone knows what they are expected to deliver, and reduce friction, because a decision taken by the co-founder who owns that area does not have to be renegotiated at every meeting.

What are the classic roles (CEO, CTO, COO, CPO)?

In a team of two, roles often split between one person who builds the product and one who sells it. See our guides on finding a technical co-founder (CTO) and finding a business co-founder.

How do you divide roles according to skills?

1. 1List every area of the business: product, engineering, sales, marketing, finance, legal, hiring, investor relations.
2. 2For each area, note who has the strongest experience and who actually wants to own it.
3. 3Assign a single owner per area, even if several co-founders contribute to it.
4. 4Identify the areas nobody covers well and decide whether they will be learned, shared or left to a future hire.
5. 5Try this organisation for a few weeks, then adjust it together.

If an essential skill is missing entirely, it may be a sign that you need another co-founder. Talent profiles on EasyCofounder show the role each person is looking for and their skills, which makes that search easier.

Who decides what: decision areas and tie-breaking

Dividing roles also means dividing decisions: each co-founder decides alone on routine matters in their area, while some important decisions remain collective.

• Individual decisions: day-to-day technical choices, how sales are organised, the week’s priorities within one’s own area.
• Collective decisions: fundraising, key hires, a change of strategy, major spending, bringing in a new co-founder.
• Tie-breaking: if a disagreement persists, specify who has the last word on each type of topic, or which procedure to follow.

These rules must stay consistent with the company’s articles and the shareholders’ agreement, which set the majorities required for the most important decisions.

How should roles evolve as the team grows?

With the first hires, each co-founder moves from doing the work to managing people, a shift not everyone wants or handles in the same way.

• ✓Review the division of roles at every key stage: first employees, fundraising, a new line of business.
• ✓Accept that a co-founder may prefer to stay an expert rather than become a manager, and hire a lead above or alongside them.
• ✓Discuss titles and scopes openly before an investor or a new hire forces the question.
• ✓Set out in the shareholders’ agreement how a change of role is decided.

How do you put the division of roles in writing?

One page is often enough: for each co-founder, their title, their area of responsibility, the decisions they take alone, the time they commit to the project and the objectives expected over the coming months.

This document can be attached to the shareholders’ agreement or remain an internal document reviewed regularly. What matters is that it is known, accepted and dated.

A clear division of roles reduces the risk of disagreement, and if a conflict arises anyway, our guide to preventing and resolving co-founder conflict offers a method.
