What a fractional Chief Product Officer delivers.
A fractional Chief Product Officer gives B2B SaaS companies the strategic product leadership they need — without the cost and commitment of a full-time executive. Sally steps into the CPO seat to set direction, align stakeholders, and make the product function a driver of revenue rather than a cost centre.
Engagements are structured around your stage. Early-scale businesses often need someone to build the first product roadmap and establish a product management function from scratch. More mature scale-ups benefit from a rigorous review of existing roadmaps, pricing architecture, and team structure to unlock the next growth phase.
Product roadmaps that bridge technology and commercial goals.
Too many product roadmaps are wish lists disconnected from revenue. Sally builds roadmaps grounded in commercial reality — prioritised by customer value, technical feasibility, and the growth levers that move the business forward.
She works directly with engineering leadership to align delivery timelines with go-to-market plans, ensuring the product management function is a credible voice in board conversations and investor updates. The result is a roadmap the whole organisation can rally behind.
Setting up product management functions and mentoring product managers.
Hiring your first product manager is a milestone — but without the right structure, even talented product managers struggle to make an impact. Sally helps B2B SaaS leadership define the product management function: roles, rituals, tools, and the decision-making frameworks that let product managers own outcomes rather than just manage backlogs.
She also mentors existing product managers, raising the calibre of the team so the product function becomes a genuine competitive advantage rather than an administrative layer between engineering and the business.
Fractional CPO — frequently asked questions.
What is a fractional CPO?
A fractional CPO (Chief Product Officer) is a senior product leader who works with a B2B SaaS company on a part-time or interim basis. A fractional CPO sets product strategy, builds the roadmap, hires and mentors product managers, and aligns engineering with go-to-market — without the cost of a full-time executive hire.
When should a B2B SaaS company hire a fractional CPO?
Hire a fractional CPO when you have product-market fit signal but no senior product leadership, when your roadmap has drifted from commercial goals, when you are preparing for a fundraise and need an investor-ready product story, or when you need to build a product management function from scratch and mentor your first product managers.
How is a fractional CPO different from a product consultant?
A consultant produces recommendations. A fractional CPO owns the outcome — sitting in the CPO seat, making decisions, leading the product team, and accountable to the founder and board for product performance.
How much time does a fractional CPO commit?
Engagements typically run between one and three days per week over three to twelve months, scoped around the stage of the business. Sally tailors each engagement to deliver a specific outcome — a new roadmap, a product function stood up, or a team levelled up.
