Jim Gervaise-Brazier

Head of Investment Management Recruitment

Jim joined the Ad Idem Group in January 2017 having spent 12 years working in Investment Management recruitment. Jim set up his own recruitment firm, JGB Partners, in 2012 which he ran successfully for 5 years. A chance meeting with Ann Radford, an ex-colleague and friend, lead to Jim teaming up with Ann to establish and run the investment management division of the Ad Idem Consulting Group. Jim loves recruitment but he felt that running his own firm took him away from what he really enjoyed – changing people’s lives and matching ideal candidates into the right businesses. Ad Idem gave him the opportunity to get back to what he does best and since taking the position, he has never looked back.

Jim recruits across the entirety of functions from front to back office and works with some of the world’s leading Hedge Funds and Asset Management firms. He prides himself on his integrity and honesty and will always strive to give people the best advice he can to help forward their careers, all the while ensuring he is providing his clients with unrivaled service. For Jim, it is all about the long term, and his reputation in one of the most competitive recruitment markets speaks for itself.

When Jim is not working (though you can almost always reach him on WhatsApp!) he enjoys spending time at home with his wife, young daughter and their cats. He is also an obsessive collector and player of electric guitars. He has played thousands of gigs with countless bands across the UK, Europe and America. He has played bass for legendary 80’s pop star Tiffany, live on Strictly Come Dancing, as well as appearing at both the Glastonbury and Download Festival. He loves crime documentaries, travelling in Europe and almost all whisky.

Henry Lenehan

Senior Consultant

Henry joined Ad Idem Consulting in 2018 as a Junior Resourcing Associate having spent a brief time on work experience with another London recruitment firm. They were unable to offer him a permanent position at the end of his placement but referred him to Jim who immediately saw a spark within Henry that he knew he could nurture.

Jim was right, and Henry quickly got to grips with the world of Investment Management recruitment, utilising his natural personality to form and develop key relationships in the industry with both clients and candidates. Henry’s eye for talent saw him quickly begin to make placements and he was soon promoted to Candidate Manager and then Consultant not long after that, as his confidence and reputation continued to grow.

Henry has since undergone further training and development and is now one of the firm’s most prolific billers. With his fearless approach to business development, he now consistently pulls in business from some of the biggest names in the industry. His ability to build relationships with businesses of all sizes, coupled with his exceptional knowledge of the industry, has seen him become a trusted recruitment partner to his ever growing client base – an impressive feat in such a competitive market.

When he joined the business, Henry’s main focus was on junior level recruitment across Middle Office Operations but he has since grown into Sales, Research, IT, Performance, Risk and Distribution recruitment at a much more senior level.

Outside of work, Henry is a new dad to son Archie and a long-suffering Arsenal fan, he enjoys spending time with family (as Covid restrictions currently dictate!).

Jon Pettet

Senior Consultant

Jon joined Ad Idem Consulting in 2021 as a Senior Consultant. Prior to this he worked for two global recruitment firms covering both the Financial Services and Healthcare sectors. Jon also has experience working on the other side of the fence in operations within the Financial Services industry, with the Bank of England. 

Jon recruits for Risk and Compliance roles on a temporary, fixed-term contract and permanent basis across the Financial Services sector. His experience working for the Bank of England for over five years prior to working in recruitment, puts him in a great position to connect with candidates and clients and have a real understanding of their needs and aspirations. Above all else, Jon is passionate about helping his candidates and clients by providing them with a consultative service and being available at any time of the day! Jon’s remit includes junior risk and compliance graduate roles to C-Suite Compliance Directors and Chief Risk Officers as well as Transformation and Risk / Compliance Interims on a project basis.

Outside of work Jon likes to keep fit and healthy by running, going to the gym and playing golf. He is a forever hopeful Arsenal fan so likes to watch football games in his spare time, which tends to end in disappointment! Jon also enjoys holidays abroad and has a long list of locations to visit once travel restrictions are lifted!
