A fractional CPO (chief product officer) is a senior product leader who works with you part-time and owns one thing: the product. A part-time co-founder works across product, design, go-to-market and early hiring, and does the work alongside you rather than leading a team. If you already have a product team that needs senior leadership, a fractional CPO is the better fit. If you're pre-launch or early and the founders are doing everything themselves, a part-time co-founder usually covers more of what you're missing.

## What a fractional CPO does

A fractional CPO brings senior product leadership to a company that can't yet justify, or find, a full-time one. Typically they:

- set the product strategy and roadmap
- decide what gets built and in what order
- lead and coach the product and design team
- set up how the team works: planning, research, metrics
- represent product to the board and investors

The role assumes there's a team to lead and a product to manage. It works best once you have something live, users to learn from, and at least a few people building.

## What a part-time co-founder does

A part-time co-founder fills the gaps a founding team usually has in its first months. That means working on the product, but also on the things around it:

- deciding what to build first and what to leave out
- designing and shaping the first version
- positioning, and how you explain the product to customers
- getting to the first users, and fixing what stops them signing up
- first hires, and the story you tell investors

The role assumes there isn't much of a team yet. The work is hands-on: making the decisions with you and doing the work, not directing other people.

## Side by side

| | Fractional CPO | Part-time co-founder |
|---|---|---|
| **Focus** | Product only | Product, design, go-to-market and hiring |
| **Best stage** | Live product, a team in place | Pre-launch or early |
| **Way of working** | Leads and coaches the team | Does the work alongside the founders |
| **Typical length** | Ongoing, often a year or more | A fixed period, such as 90 days |
| **Main output** | Strategy, roadmap, a stronger team | A first version, positioning, first customers |

## What each costs in Dubai

Both are usually paid as a monthly retainer. A part-time CPO in Dubai typically costs AED 22,000–37,000 a month, depending on seniority and days per week. That's for product leadership alone; design, go-to-market and hiring support would be extra.

Part-time co-founder arrangements vary more, because they're less standard. Mine is AED 7,500 a month for 90 days, and I'm open to a mix of cash and equity. Whichever you choose, be clear about the days per week, what's included and how either side can end it.

## How to tell which you need

You probably need a **fractional CPO** if:

- your product is live and you have a team building it
- the team is busy but not sure it's working on the right things
- you need someone to set strategy and hold the roadmap

You probably need a **part-time co-founder** if:

- you're pre-launch, or have only just launched
- the founders are doing everything, and product isn't your strength
- you need help deciding what to build, not managing who builds it
- you also need help with positioning, first customers or first hires

If you're somewhere in between, start with the part-time co-founder model for the first few months. Once there's a team and a live product, a fractional or full-time CPO becomes the natural next step, and you'll know exactly what to look for.

## Questions founders ask

**Is a fractional CPO the same as a product consultant?**
No. A consultant usually reviews and recommends. A fractional CPO is part of the leadership team and accountable for the product's direction over time.

**How many days a week does a fractional CPO work?**
Commonly one to three days a week, depending on the size of the team and the stage of the company.

**Can a part-time co-founder become a full co-founder?**
Sometimes. Working together for a fixed period is a good way to find out whether you want a longer partnership, without committing a large share of equity up front.

**Do I need a CPO before I raise?**
Not usually. Investors in early rounds look for a clear product direction and evidence that users want it. Someone senior can help you get there without holding a CPO title.
