Chief Financial Officer / CFO - PE-backed AI Martech SaaS. Hybrid - 19932

London

Gresham House Ventures have just backed us, and now we’re ready to back you.
We’re scaling fast - £3M to £15M ARR, backed by serious capital and have a clear growth strategy.
We see finance as a competitive advantage, not a control function. We understand achieving a 10x £150 Million exit in the future needs the right expertise to build enterprise value - not just report it - and before the real acceleration begins. Not only that, but we also know titles don’t create wealth - equity and timing do, and for you to do your best work you’ll need real ownership and a collaborative leadership team that’s ready for you to lead with vigour and deliver your best work.
If you're ready to be instrumental in this journey, actively shaping where we invest, how we grow, and how we position for maximum value at exit, we’d love to hear from you.
We are Modo25 / ASK BOSCO.
Ready for your next adventure?

The Role at a Glance:
CFO Chief Finance Officer
Hybrid Leeds HQ, 2 Days per Week
£90,000 - £150,000 + Equity
Plus Benefits: 4-day working week, 30 days annual leave incl bank holidays, health insurance, critical illness cover, life insurance, retail & leisure perks, electric car scheme
Values & Culture: Outstanding Company to Work For 2024
Company: B2B SaaS (AI-powered marketing analytics) & Digital Marketing services
Pedigree: Visionary Founder. Backed by renowned tech entrepreneurs, including co-founder of SkyScanner. Profits with Purpose — 10% of profits donated to 1moreChild orphanage annually
Markets: Marketing & eCommerce Agencies, eCommerce retailers
Your Skills: Qualified - ACCA, ACA, CIMA. Hands-on Financial Leadership with Scaling Tech Co - expertise with a sale or significant funding round.
Who we are:
We’re building a high-growth AI SaaS business alongside a profitable agency, and we’re looking for a CFO who wants to help shape the story - and the exit.
Modo25 is a digital marketing agency working with enterprise brands. ASK BOSCO is our AI-powered marketing analytics platform that predicts marketing ROI with 96% accuracy. Together, we're scaling from £3m to £15m over the next three years, backed by Gresham House Ventures, with a clear path to exit at a 10x revenue multiple.
You will be instrumental in this journey.
Your Expertise:
You are a commercially astute, qualified accountant (ACA, ACCA, CIMA) (ideally Big-4 trained) with a proven track record of helping ambitious businesses scale at pace. Having spent several years inside a high-growth scale-up, you are fluent in SaaS metrics (ARR, churn, NRR, LTV:CAC) and comfortable operating in the complexity that comes with rapid expansion, funding rounds and exit-readiness. Based in, or excited to relocate to Leeds or happy to be onsite 2 days per week, you thrive working closely with a leadership team and shaping the future of a business from the inside.
What truly sets you apart is your breadth of perspective: experience across SaaS and professional services, exposure to M&A, and a genuine commitment to building a business that balances performance with purpose through progressive ways of working and meaningful social impact.
Why This Role Is Different
You'll be joining a leadership team that genuinely wants finance at the heart of decision-making. The CEO and COO are ready to hand over the numbers to focus on growth, product, and market expansion. They're not looking for a gatekeeper.
They're looking for a commercial partner who can:
Build reporting - real-time dashboards and MI to run the day-to-day business, as well as report at Board level
Navigate a hybrid model - agency retainers alongside SaaS subscriptions, each with different economics
Spot growth opportunities the rest of us haven't seen - you'll have access to data nobody else is interrogating
Prepare the business for exit - clean books, compelling story, data room ready, and a CFO who can hold their own in due diligence
We’ve built today, for you to build tomorrow
We’re not perfect - and we’re honest about that. Today, our finance function is a fractional CFO for half a day a week, a high-calibre new Finance Manager, and a COO who’s been carrying more financial responsibility than she should. It works, but it’s not built to scale. With funding in the bank, investors on hand and an ambitious scale target we need you at the helm - dedicated financial leadership building out robust processes, embedding best practice, and making proactive, insight-led decisions about what we should prioritise, invest in, and do next to support sustainable growth.
You'll be managing two business models with different rhythms, different metrics, and different levers. If that sounds like a headache, this isn't for you. If it sounds like an interesting puzzle, let’s talk.
What We Offer
£90,000 - £150,000 base salary depending on experience
Equity - real ownership with meaningful upside if we hit our exit targets
Four-day working week - we believe in output over hours, and we've made it work
A seat at the table - you'll report directly to the CEO and work closely with the COO and Gresham House
An 'Outstanding Company to Work For 2024' - we take culture seriously
The Process
We’re taking a considered, high-bar approach to this hire. Our interview process is intentionally rigorous because we’re focused on attracting true A-players, and we’re prepared to invest the time to find the right fit. You can expect a thorough, high-quality process that includes psychometric assessment and a commercial case study-designed to understand not just what you’ve achieved, but how you think and make decisions.
Target start date: June 2026
Ready to make a move?
If this sounds like the challenge you’ve been looking for, a true commercial partner role rather than just another finance position, we’d love to hear from you. No cover letter is required; simply share your CV along with a couple of sentences on what drew you to the opportunity.
We’re excited to meet you. Team Modo25 / ASK BOSCO
