Not all financial modelling experts are the same

Are you tired of conventional, slow-paced financial modelling that leaves you in the dark until the last minute? We were too. 

That’s why we revolutionised modelling. Because faster insights lead to faster solutions. Whether for project finance, renewable energy, infrastructure, mergers and acquisitions, business modelling or other major investment opportunities, your financial model isn’t just a tool—it’s the bedrock of your future. 


So, whether you’re looking for a model build, an audit, or training, we’ll help you identify, understand and solve issues faster. Now you can make better, faster decisions with confidence.

We don’t just deliver accurate models; we ensure you’re always a step ahead.

Why Gridlines?

We’re not just financial modellers; we’re pioneers redefining the industry. That’s why, in 2023, we audited more financial models than KPMG, Deloitte, EY, and PwC combined. 

Financial modelling isn’t part of our service – it’s our sole focus. As dedicated specialists, we make it our business to lead the industry in new ways of working to ensure unparalleled precision and expertise.

Let us help you shape your industry with precision, insight, and strategic foresight.
