“The due diligence reports were well presented with some excellent insights and we found PMSI to be very curious about the complexities of our business yet were crisp in drawing conclusions. The litmus test is that we were able to use their report to inform our operations let alone the transaction.”

R V Ahilan, CEO, LOC Group

“A pleasure again to work with you and your team and an excellent piece of work delivered at the end, many thanks.”

“Gareth and the PMSI team consistently provide highly valuable insights and analysis that are critical in evaluating potential investments. We have chosen to work with PMSI on multiple projects because of the quality of work produced, the specialist expertise of the team in the healthcare and life science sector, a flexible approach to scoping and efficient project management.”

Lauren Edison, Investment Manager, Apposite Capital

“Having worked with PMSI for the first time during our acquisition of Inciner8, I found them to be diligent, efficient and very collaborative throughout the process. They got to grips with our requirements quickly and provided a well-prepared report covering the full scope of information and intel requested at the outset.”

David Butler, Chiltern Capital

“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.”

Jolyon Latimer, Partner, CBPE

“PMSI supported Mobeus on a focussed brief with an impressive speed of engagement and level of resourcing. Customer interviews were handled sensitively and generated detailed commercial insights. The report conclusions were clear and comprehensive with the findings critical to enabling Mobeus to complete the transaction.”

Freddie Bacon, Investment Director, Mobeus
