Chief Financial Officer | Fast-Scaling B2B SaaS Business | London (Hybrid)

The Client:

Harmonic is delighted to be retained on the search for a Chief Financial Officer with a fast-scaling B2B SaaS business headquartered in London. The company has built a loyal and expanding customer base, grown in a disciplined and capital-efficient way, and has been quickly gaining market share within it's space.

Well capitalised and backed by high-calibre investors, with an international presence the business is now focused on accelerating commercial expansion and putting the operational foundations in place to support the next stage of the journey as the company becomes more mature and established within it's sector.

As the business enters this pivotal period, it is looking to appoint a CFO as one of its most significant senior hires to date.

The Role:

Reporting directly to the CEO, the CFO will sit at the centre of how the business is run and how it scales. This is a commercial, forward-facing appointment rather than a purely operational one. The successful candidate will act as a trusted sounding board to the CEO, bringing financial discipline and strategic clarity to the questions that matter most: where to invest, how to play a key role in future funding for the next stage of growth, and how to scale at pace without loosening financial control.

Key Responsibilities:

• Act as the CEO's principal commercial partner across strategy, capital allocation and investor relations.
• Own and evolve the financial model as a live tool that shapes decisions on hiring, commercial investment, pricing and product priorities.
• Take the lead on investor relationships and drive preparation for the next funding round, positioning the business for future capital raises as it scales.
• Build out and professionalise the finance function, maturing the team, systems, controls and reporting from an early-stage footing into something fit for a business of scale.

What We Need to See:

• ACA / ACCA / CIMA qualified, or equivalent.
• A strong track record as a senior finance leader within a venture-backed B2B SaaS business.
• Hands-on experience managing investor relationships and contributing to fundraising processes.
• Someone who has steered a business through a period of rapid growth, ideally across the Series B stage, in a role that influenced decisions rather than simply reported on them.
• Experience building out and professionalising a finance function as a business scales.
• A strong interest in applying AI, automation and agentic processes within finance, with a track record of modernising ways of working.
• First-rate financial modelling skills, with the ability to build and stress-test complex models, scenario analyses and cohort analyses personally.
• A clear history of raising the standard of financial decision-making across an organisation.

What We Would Like to See:

• Experience modelling or supporting international growth.
• A background in enterprise software.
