A little about us

At Mighty, we believe small businesses deserve better. Better software, better service, and better support.We’re not just accountants.

We’re product people, problem-solvers, and small business champions. We know how frustrating and outdated traditional accountancy and clunky software can feel - especially when you're trying to run a lean, agile company.

So we built something better.

Our Story

We're two people with deep roots in accountancy, and even deeper frustrations with how needlessly complex and expensive it can be, for relatively simple businesses.

James has spent over a decade in the industry, working as both an accountant and a product manager across both a leading contractor specialist and top-20 firm. His experience with freelancers, contractors and small businesses showed him first-hand how little traditional solutions really serve these clients.

Mark is a developer with over 20 years’ experience in the accounting space. A serial hackathon winner at Xero and QuickBooks, he’s been building better tools for accountants for years and knew it was time to create something different for small businesses.

Together, they built Mighty: a modern accountancy service with custom-built software designed specifically for the needs of small, service-based limited companies. No bloated features. No generic tools. Just exactly what our clients need and nothing they don’t.

Our ownership & ethos

We're small, mighty and proud.

We don't chase venture capital or investors — we're customer-funded, customer-focussed and they're the only people we answer to.

We don't put hyper-growth on a pedestal. In fact, most of our new clients come from referrals which is all the proof we need that we're doing something right.

Mighty is run by Mark (developer & dad), James (consultant & dog dad), and our amazing team based across London, Liverpool and Cambridge.

We invest heavily to create best in class software and recruit outstanding accountants to help our customers save tax, time and stress.

Your success and satisfaction is all that matters to us. So if you'd ever like to chat, complain or share any suggestions reach out to our CEO directly via james@mightyaccounting.com or +44 07958 590 227.

We hope to hear from you soon.


Our Mission

To make accountancy simple for the small but mighty.

We’ve tailored every screen, every feature, and every part of our service to the types of clients we know best. Mighty isn’t designed for everyone and that’s exactly why it works so well for the people it is.
