Client Testimonials
Ross Smith, Director, AIRP (now part of Amber River)
We dealt with a few people before and you could tell they were just going through the motions. I wanted somebody to be more involved and engaged; that’s where Pieter and M&A Chambers were completely different to anybody else.
Their list of contacts and also understanding of what we were looking for in a deal undoubtedly helped, through every stage. They have a wealth of experience of matching buyers and sellers.
Pieter made us feel so relaxed about the whole process.
Spalé Marcinko, Director, Moyses Stevens Flowers Ltd
From first engaging Pieter we felt he had our best interests at heart. He took time to understand our business, whilst constantly paying attention to our commercial targets.
Pieter has been a trusted Lead Advisor to us during corporate restructures, commercial acquisitions as well as our international expansion, and we would be delighted to recommend him to Founders looking to exit or to Directors looking to acquire businesses.
Ross Murray, Managing Director, VivereXO
As Managing Director of The VivereXO Group, I have had the pleasure of working with James on various acquisitions and sale transactions, covering various territories. He adopts a pragmatic and logical approach to every transaction, always adding value to the process and presenting solutions in more complex deals. Very much an “old school operator”, James’ attention to detail and streamlined approach is somewhat a breath of fresh air. His commerciality and approachability make him a pleasure to work with, and I could not recommend them highly enough to mediate or be an integral part of any commercial transaction.
James Lyons, Corporate Director, Lawrence Stephens Solicitors
Pieter has been lead corporate finance adviser on various M&A deals we have worked on together in recent years. He impresses clients with his commercial and solution-orientated approach and, most of all, is a pleasure to work with.
Damien Field, Managing Director, MM-Eye
We came across Pieter in 2020 when an MBO opportunity arose for us. He demystified the process and guided us on the path to fulfil a long-held dream.
We view Pieter as a true business partner, helping present business exit options that delivered financial value to us as owners and passed the business to the next generation. He was lead consultant on this deal, orchestrating all parties towards a positive outcome in 2023.
Pieter understands that business is not only about the figures, but also about people and intangible value. He is able to navigate between both to identify commercially sound solutions and make them a reality.
Owner of a professional services business in Kent
James Gosling really helped us through a stressful period. He explained the requirements fully and was always available for any questions we had. He was very approachable and supportive. We would have no hesitation in recommending him when considering selling your company.
Managing Director of a £20m business in Cambridge
Superb partnering to ensure we had constant and effective communications, working alongside us, guiding us expertly through many issues we faced. Should the opportunity arise, we would 100% use the services of M&A Chambers again.
Owner, £1m business in Hertfordshire
James Gosling was a perfect consultant to sell part of my business, he was very helpful from day one and he gave me a lot of valuable advice along until we completed.
Owner, £1.5m Turnover Music Business
It’s been a pleasure working with James. His hard work in negotiations has been first class and pivotal in the process.
Managing Partner of a Corporate Finance house, whom we collaborated with on a £3m transaction
Having advised clients on numerous transactions over the years it was always important to me that any transaction would have communication and momentum. James remained attentive and informative throughout the process ensuring all parties were fully aware of the progress being made. The successful outcome of the transaction was a result of James’ diligence.
Oliver Wade, Partner at Movar Reply
I’ve known Pieter for many years, and having recently worked alongside him on the Movar / Reply transaction, I can confidently say he is an exceptionally diligent and professional adviser who truly knows his market. As our Lead Adviser, Pieter played a key role throughout the process, demonstrating a deep understanding of both the deal dynamics and the people involved. His proactive approach, attention to detail and ability to anticipate challenges meant that the transaction progressed smoothly from start to finish.
What really sets Pieter apart is his ability to build long-term relationships based on trust. Given our history and the importance of achieving a successful outcome, I knew we were in safe hands, and he more than delivered; ensuring strong communication, managing expectations effectively and always keeping momentum at critical stages of the deal. I truly think Pieter’s ability to manage the deal to completion; with us as his client, our buyers, and all the advisers (legal and financial) on both sides, was exceptional.
I would have no hesitation in recommending Pieter and the wider M&A Chambers team to anyone considering a transaction. Their expertise, dedication, and commitment to delivering successful outcomes is clear in everything they do.
