Recent transactions

In order to secure the right investor we knew we needed bright and persuasive presentation of Brady Solicitors and the niche sector we work in. PMSI were outstanding throughout the process and grasped the nuances and opportunities swiftly. Their commercial due diligence was clear, insightful and thorough, and they represented us to potential investors with professionalism and a strong understanding of what makes Brady and the sector valuable.
They were responsive, practical and collaborative throughout, helping us achieve an excellent outcome for both the team and the business. I would not hesitate to recommend PMSI and Aditi and Catherine to anyone considering a similar step.
Brady Solicitors Colin Hussey, Executive Director
It was a pleasure to work with Gareth and the team at PMSI, who supported us with VCDD and helped to deliver a great new home for Gentronix and a strong exit for the shareholders.
Gentronix Matt Tate, CEO
The PMSI team delivered a very objective approach and provided us with some very helpful insights into our customer base and wider industry. They are professional and very detailed in the work they do so we can only recommend their services.
Deltron Lifts Director
PMSI helped us quickly get up to speed with the key trends in an exciting but relatively niche sector. The team used a bottom up approach to determine market size and growth combined with market interviews to assess ETL’s competitive position. PMSI’s work was invaluable in enabling CBPE to assess ETL’s market opportunity and complete the transaction within the required timeframe.
CBPE Jolyon Latimer, Partner
Working with PMSI was a great experience. The result was a fantastic outcome for the team and the business. I would not hesitate to recommend PMSI.
Phoenix Health & Safety Nick Higginson, CEO
The PMSI Healthcare team were pivotal to the success of our transaction – rapidly delivering an exceptionally high quality of work despite demanding timescales.
Spire Healthcare Elizabeth Potter, Director of Strategic Projects
I have reviewed the PMSI report, it really is excellent, thank you very much. There is some great research in here and it will hugely benefit us in growing these businesses, so thanks a million.
Learndirect Wayne Van Resburg, Chief Executive
PMSI took the time to understand our business and how it operates. It was particularly pleasing to see that the team were happy to get ‘in and amongst it’, speaking at length with key members of staff rather than basing their research solely from sitting behind a desk. Their interaction with customers during their research was extremely professional, their questioning to them was very relevant and helped us get a real and accurate picture of how we are perceived by them. Because of the work that they put in at the start of the process, the final report gave an accurate view on the strength of our business and the opportunities that exist to continue our growth story. I would have absolutely no hesitation in recommending David and the team to anyone looking for a Commercial Due Diligence provider.
Workdry International Richard Brown, CEO
PMSI went further than analysing the numbers – they understood our model, our market, and why we were different. Their clear insights helped tell a sharper story to investors, which made a real impact and played a meaningful part in the strength of our deal outcome.
