Here since the beginning

Since Infrastructure became an investible asset class in 2006, we have been the retained search partner of choice to the investors and organizations transforming the world’s infrastructure and, now, driving the energy transition. In this time, we have successfully completed more than 2,000 senior searches.

Access & influence

One Search at an industry event

Part of the community

We are not just a search firm. We are a fully fledged member of the infrastructure and energy transition community.

We participate across the network, at industry events/conferences and engage with the likes of the Women’s Infrastructure Network. We also aim to make a positive difference to the diversity of this community, via our global mentorship/internship program, Young Women Into Finance.

Our clients

Our client list is a veritable Who’s Who of the investors transforming the world’s energy, resources and industrial infrastructure.

I have worked with One Search on a number of occasions, both in recruiting new positions, and as a candidate myself. I have found them to be a pleasure to work with and, whichever side of the recruiting process I’ve been on, they have taken the time to understand what I am after from either a new role or recruit. As candidate, I received lots of useful advice and encouragement, and as a recruiter, I have received a strong range of candidates accompanied with honest feedback and appraisals, all of which has helped make the process as streamlined as possible.

It had been obvious to us for many years that the only way real gender diversity in our sector was going to be achieved and sustained was if more young women wanted to come into it.

After years of talking heads getting us nowhere in this regard (female entry level hovered between 12-18% for ten years in the decade 2008-2018), in 2018 we decided to do something about it.

Introducing the future

Our sister company, Infrassocs is here to revolutionize junior level hiring across infrastructure and the energy transition. We identify the most talented juniors and partner with them as they navigate their early career.
