Financial Modelling:
Let’s get clear on the numbers.
Flying blind, second-guessing decisions, or stuck arguing about whose numbers are right? We help ambitious businesses build financial models that bring clarity, confidence, and alignment - so you can make better decisions faster.
Financial Modelling is about understanding what really drives your business forward - where growth comes from, what it costs, and how today’s decisions shape tomorrow’s outcomes. Whether you need a model for planning, fundraising, or simply to get everyone on the same page, we’ll build something that’s robust, usable, and genuinely helpful.
What is Financial Modelling?
With us, it’s a focused, structured service designed to help you understand how your business actually works.
We don’t just build models and hand them over. We work with you to identify the real value drivers, and translate complexity into something you and your stakeholders can use. That means clear assumptions, sensible scenarios, and a model that becomes central to you operations and supports decision-making.
To grow confidently, you need more than a forecast. You need a model that reflects your strategy, your operations, and the realities of your business. That’s exactly what we help you build.

“Pay As You Go COO helped us to set our goals in a really clear way. The team feel so motivated and we're already seeing results."
But why choose us?
We understand the breadth of challenges in building a business and raising for growth because we're both serial business-builders. We're startup operators with 35+ years experience across scaling startups, leading VC funds, and large corporates.
We know what good financial models are really for.
We’ve built and used financial models as operators and advisors, and we've seen countless from inside VC.
We know where models often go wrong: over-engineered, disconnected from reality, or built to impress rather than inform. We focus on what matters - clarity, credibility, and usefulness.
Our work helps you cut through noise, understand your options, and make decisions with confidence, whether you’re planning for growth, preparing for investment, or simply trying to run the business better day to day.
