Ann Radford

Founder & CEO

Ann has had a highly successful international career spanning 25 years in interim executive search.

After graduating from the University of Oxford, her recruitment career started at one of the world’s largest global HR and recruitment firms and she became a prolific biller and highly respected Director in both the permanent and interim space.

Having built her reputation among Senior Management within SMEs and Private Equity clients, as well as internationally listed organisations across all hierarchical levels of finance and project management, clients now reach out to Ann when they or their portfolio companies require specialist interim talent. At pre and post deal pain points she provides them with C-Suite professionals to support their business objectives from both a finance and transformation perspective.

Armed with an enviable network of clients and candidates, she has the ability to intuitively match individuals to roles with a comprehensive understanding of the brief process, shortlisting the most suitable candidates and taking the mandate through to completion.

Ann’s hands-on approach to recruitment is consultative and she understands that not only is experience important to a role, the culture and personality fit are equally as vital and can often mark the difference between success and failure.

Her raison d’être is to make the recruitment process fun and hassle-free. She will always give an honest answer and maintain an open dialogue with clients and candidates, some of whom have been with her for many years.

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.


Sam Barrett

Group Business Development Manager

Sam joined the Ad Idem Group in 2017, having spent 10 years within international sales working with clients across Europe, Asia and the Americas within varying business sectors from finance and insurance to media and advertising. 

His natural ability to build and develop relationships quickly served him well within the world of recruitment, where he came up through the ranks, quickly working his way up from Candidate Manager to Executive Headhunter within 3 years.

In his time with the company he has supported clients across all Group entities to include finance & accounting, investment management, executive search and private equity. Now working as Group Business Development Manager, Sam looks to apply his trade within the latest offering from the Ad Idem Consulting Group and extend his client base across the pond.

Having already successfully helped develop two business units and launch an external subsidiary in a totally new field, he has a proven ability to learn and adapt to new environments and quickly develop an understanding for the differences within each market of operation, making him a key asset to all areas of the business.

Working directly alongside Ann, he looks to leverage off this network, experience and success he has had within the Group to date, to help grow the company’s global footprint across the U.S. and Canada. His flair for relationship building and client management plays a vital role within the wider group and he now plays an equally important role in the generation of revenue for Ad Atlantic.

When Sam is not working, he enjoys spending time with his friends and family or can be found playing cricket, golf, or watching either Chelsea or Saracens with his girlfriend.

Henry Lenehan


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 soon-to-be dad who is a long-suffering Arsenal fan, and he enjoys spending time with family (as Covid restrictions currently dictate!).
