Fractional Chief Product Officer

What is a fractional CPO?

A fractional CPO is an experienced Chief Product Officer who works with your company part-time, typically one to two days a week on a monthly retainer. You get senior product leadership — strategy, roadmap, discovery and delivery — without the cost, equity or commitment of a full-time executive hire.

How much does a fractional CPO cost?

Retainers run £4,000-£10,000 per month for one to two days a week, depending on scope and stage. UK day rates, retainer bands and IR35 are covered in full on the fractional CPO UK page.

How many days a week does a fractional CPO work?

Most engagements run one to two days a week. One day suits strategy, roadmap review and weekly product rituals. Two days adds hands-on discovery, spec writing and delivery. Days are scheduled as fixed slots so the team knows exactly when product decisions get made.

When should a startup hire a fractional CPO?

Hire a fractional CPO when product decisions are costing you money but you don't yet need a 40-hour-a-week product function. That's usually pre-seed to Series A: you need strategy, roadmap discipline and MVP delivery, and the founder has become the bottleneck on product.

What's the difference between a fractional CPO and a consultant?

A consultant advises and hands over a deliverable. A fractional CPO is embedded in the team, owns outcomes, makes decisions, runs the product rituals and is accountable for what ships. The engagement is measured on product results, not on a document.

What's the difference between a fractional CPO and a fractional CTO?

A fractional CTO owns technology architecture, engineering hiring and infrastructure decisions. A fractional CPO owns product strategy, roadmap, discovery, and, in AI-first teams, model choice, prompts and evaluation. In early-stage AI startups the two overlap: I ship working MVPs with Claude, Cursor, Lovable and Bolt, which covers the technical MVP surface a CTO would otherwise own. Beyond MVP, most teams need both.
