Who is behind SJ Finance…
I’m Sean Mooney and I founded this company with one clear goal: to provide professional services firms with the precision, simplicity, and strategic insight to drive significant growth.
With over 15 years in senior finance roles – working with start-ups, SMEs, and large international groups – I’ve seen firsthand the impact a well-built financial model can have on business critical decisions.
My background as a Group Finance Director for complex, multi-entity businesses gave me a unique perspective on the financial challenges facing professional services firms.
I know the tough questions that shareholders, lenders, and investors ask, and I understand how essential it is to provide clear, actionable answers. That’s why we build models that do more than just handle data – they simplify complexity, turning financial information into insights that make decision-making faster, clearer, and easier.
How we work
At SJ Finance, we leverage the latest in Excel modelling, automation, and Power Query to create financial models that are more accurate, faster to load, and easier to update than most of the models currently in use.
By automating data flows and enhancing real-time reporting, our models reduce your team’s time spent on manual data entry by up to 75%, allowing you to focus on growth and strategy.
And unlike traditional modellers who may deliver a one-time solution, we design each model to evolve with your business, providing lasting value well beyond the initial transaction.
But our commitment doesn’t end with building a model. We take a holistic approach to bring you a comprehensive suite of expertise that supports your financial operations, strengthens forecasting, and drives sustainable growth.
If you’re looking for a partner who understands both the technical and strategic side of financial modelling, we’re here to help. With SJ Finance, you’re choosing a solution that adapts to your business as it grows and empowers you to seize each opportunity for long-term success.
