Our story

We build and run smart finance functions® and data analytics for fast-growth and complex businesses.

Our mission is to deliver relevant insight that enables better business decisions.

flinder and our sister firm, Next Level Business, are both part of Ascendant, a new group leading the way in “Finance as a Service”.

How it started

In 2017, there were two accountants, Alastair and Luke, with a passion for technology and data, and a belief that the needs of fast-growth tech companies weren’t being met by established accounting firms; there was too much gazing into a rear-view mirror and a passive nod-along ‘involvement’ in the business.

They wanted to up the ante. They wanted to harness cloud technology to give founders real-time meaningful insight and be a commercial voice at the Board table.

So, they set out to bring their Big Four experience and knowledge of best practice finance functions, to tailor it for scaling, fast-growth companies. And flinder was born.

Pioneering change

Since then, flinder has been a disrupter and a pioneer; shaking up the accounting industry and acting as a catalyst for change. It’s at the forefront of the industry in its creation of smart finance functions® to accelerate the growth of tech, SaaS and e-commerce businesses.

flinder is now the technology and data-led finance partner to some of the most exciting fast-growth businesses helping them to improve performance, prepare for investment and scale operations.

The benchmark

While we’re proud to have won a number of awards on our journey, we're also involved in judging others across accounting, tech and e-commerce awards. We also help shape the future of the profession contributing to various panels, advisory boards and steering committees.

Thanks to our team and clients for continually pushing us.

We don't just talk fast-growth, we live it

Our ethos

Fast-growth business leaders need responsive reporting and relevant insight now, not tomorrow.

We think finance should be all the things you are. Technology-driven. Data-led. Agile. Commercial. Strategic. Insightful.

We cut through the fluff to deliver meaningful, real-time insight. We get you ready for funding. We support you on the Board. With our help, you have the insight and evidence to tell a great story about your business.

We know what investors want. Companies we have worked with have raised over £250 million. With our support, you will continue to grow.

What's the deal, why a butterfly?

flinder means butterfly
Both our founders have a deep and personal connection to the Dutch language and to the word ‘flinder’ itself.

The butterfly effect
The butterfly effect is the idea that small, apparently inconsequential events can have a profound impact later. For example, the flutter of a butterfly’s wings changing the course of a tornado.

Transformation
During its life cycle, a butterfly transforms from an egg and a caterpillar to an adult butterfly. At flinder, it's our goal to support our clients on their growth journey and help them transform their business too.

In the context of flinder, the way we do things can have a lasting impact on our client's business. Even small, or what we think are obvious changes we make in their business, can have a profound impact on them and their growth.
