Tim Walton

Principal, Portfolio / CFO

Tim leads our Portfolio Practice in Europe, supporting a diverse set of investors from VC, PE and Core Infrastructure, on building robust and effective leadership teams at the executive and non-executive level across their portfolios. 

Tim began his career with One Search, where his passion for sustainability and decarbonisation was born. After a few years, he took the opportunity to explore life in a leading tier 1 search firm as part of their Global Industrial Practice, where he successfully worked on the appointment of C-level executives across hydrogen, transport, energy technology and advanced manufacturing as well as the build out of several pioneering decarbonisation investment platforms, globally. Tim returned to One Search in 2021 to focus on continuing to make an impact through talent.

Outside of the office, Tim is a keen athlete having represented GBR in sailing and water polo during his younger years. Residing in Dublin, Ireland, Tim now spends his time in the Wicklow Mountains on his bike and racing in the Irish National Series.

“Changing jobs during COVID was not easy. One Search were instrumental in keeping the interview process on track, feeding back to me as a candidate so that I felt comfortable with the job fit and culture during a period of mandatory Zoom interviews, and ultimately making sure both sides were happy when it came time to sign the contract. Their approach was just the right amount of involvement at just the right times.”

Jennifer Smith

“I hired One Search to find us a new CFO in 2020, and was impressed with the speed and agility with which they successfully completed the assignment”

Daniel Seiner

One Search introduced me to Porterbrook, and then went on to partner with me to build my team.  I have been impressed with their efficiency; in a recent process they were able to identify suitable candidates, deliver the shortlist and run a selection process that led to the successful candidate accepting our offer, within just six weeks of the process starting.
