Green Square Corporate Finance

Secure the right deal with advisors who genuinely know your sector. Corporate finance specialists for ambitious, owner-managed businesses.

Expert M&A advice underpinned by sector insight, sharp judgement and a clear understanding of what matters to you.

Selling an independent business is rarely straightforward. We work with shareholders to prepare well, move with confidence and secure the right outcome when the time comes.

Green Square is led by a team who know this journey firsthand having operated on both sides of the table – building, scaling and selling marketing services agencies themselves. That perspective makes a tangible difference. We understand the commercial stakes, but we are equally alive to the emotional realities of transferring ownership of something you have created. It’s why our advice is clear‑headed, pragmatic and grounded in real experience.

We are supported by a high‑calibre team of analysts, researchers, copywriters and client service specialists, alongside an Advisory Board of seasoned entrepreneurs and respected industry figures. Together, we bring depth, perspective and momentum to every engagement.

We are deeply embedded in the market. Our team regularly speak at industry events, contribute to the press and stay close to the conversations shaping the landscape. That insight feeds directly into our client work, ensuring we give advice that is current, relevant and commercial.

Our Corporate Finance services

Whether you’re considering a sale, looking to grow organically or via acquisition, or simply need a clear, well-grounded assessment, we provide the insight and support for you to plan and move forward with confidence.

Mergers & Acquisitions

We advise shareholders of independent businesses through some of the most important decisions they will ever make. Our M&A work typically focuses on companies with enterprise values between £10m and £100m, where preparation, positioning and execution are critical to success.

Our experience spans a wide range of transaction scenarios, including sales to trade and private equity, and management buy outs. We start by understanding your business and what matters to you. Whatever the route, our focus is always on achieving the right outcome for shareholders.

We act predominantly for vendors. That means our advice is independent, clear headed and firmly aligned with your interests. Our fee structure reflects this too, ensuring we are fully motivated to secure the most rewarding outcome for our clients, not just to get a transaction over the line.

Having advised on numerous successful transactions, we bring a rounded understanding of what makes a business attractive to buyers, how value is truly assessed and where deals are won or lost. This experience informs how we help clients prepare, position their business and negotiate with confidence.

Drawing on years of experience, ongoing research and strong relationships with acquirers around the world, we have developed a deep understanding of the global buyer landscape. This insight enables us to identify the right potential partners for your business and create the competitive tension that drives the best possible outcome.

We are proud of the reputation we have built and the strength of the relationships behind it, with the vast majority of our work coming through recommendation. We never take that trust for granted and work hard to keep earning it.

Ascension Day

The Ascension Day is a high impact, one day workshop designed to sharpen performance and accelerate value creation. It brings shareholders and management together to focus on what really matters - where value is created, what buyers look for and what is needed to optimally position the business and drive the next phase of growth.

Ahead of the session, we carry out a focused review of key information. On the day itself, we share our detailed assessment of the business and challenge thinking through structured, practical discussion. We concentrate on the value drivers that influence acquisition decisions, with a keen eye on personal ambitions and longer term objectives. This ensures priorities are aligned from the outset.

The result is a clear, prioritised action plan. One that cuts through complexity and sets a confident direction for growth, performance and value maximisation.

Consultancy

Business leaders face decisions that shape the future of their company. They need trusted, confidential guidance from people who understand the pressures, the trade offs and the bigger picture. Someone to think alongside them, challenge assumptions and bring clarity when the stakes are high.

Without experienced, independent input, it’s easy for owners to miss opportunities or lose momentum, revisiting the same questions without moving forward. The right perspective at the right moment can make all the difference.

That’s where our Trusted Counsellors come in. A carefully selected group of highly experienced individuals, they work directly with agency leaders and management teams to provide clear direction, challenge thinking and support better decision making.

Engagements can be structured on an ad hoc basis or as an ongoing relationship, depending on what’s needed. Every situation is different. Our role is to bring experience, perspective and focus, helping leaders make decisions and move forward with confidence.

What our clients say

  • We had been approached by several potential acquirers and were uncertain how to establish suitability and whether we would benefit from a wider market process. Green Square quickly understood our business, people and culture, and worked with us to determine the best fit for Given and its team on a strategic and personal level. Working closely with our team, they negotiated an outcome that was great for all parties involved. Andrew and the Green Square team were a pleasure to work with and we always felt they were on our side, working openly with other advisors, and the buyer, to find solutions to the inevitable challenges that arise during this type of process. Green Square’s clarity and direction made a real difference to how all of us experienced the process and, critically, their expertise enabled us to get a better deal.
    Becky Williams

    Founder of Given

  • We’ve said it before, and we’ll say it again. You’ve been true pro's, a rock, stable, reliable support. You’ve also become trusted friends. You kept on believing when we maybe had our moments of doubt. It’s a skill what you guys do and you’re bloody good at it. Thanks for believing (or faking it when you didn’t). MASSIVE RESPECT. We couldn’t have done it without you (or your incredible patience!). Thank you for the calm advice over such a long time. Thank you again for your incredible hard work and resilience to get us there in the end.
    Jez Nelson and Steve Ackerman

    Somethin’ Else

  • I cannot recommend working with Barry and the team at Green Square highly enough. We absolutely couldn’t have done this without them. It’s been a journey and they’ve been with us at every step of the way. Their counsel has been impeccable and not least, it’s been a total pleasure. Barry’s strategic and financial acumen is second to none, only matched by his calm. He has been a true inspiration to me and the team and long may that continue.
