“I was wrapping up our annual hiring stats, which prompted me to look across the rest of our team, and did you know that HartleyCo placed 50% of our entire DS/ML/Software team? It's been a real pleasure working with you and look forward to continuing working with you next year. Thanks for your continued support and guidance - and answering all my questions when it comes to writing our job specs and understanding the market better. It's been really helpful. Do send my best wishes and thanks to the wider team - particularly Chris whose patience is never wavering.”

I had an excellent experience working with Charlie from HartleyCo, during our search for engineers in the UK. Charlie took the time to deeply understand not only our technical requirements, but also our company culture, values, and long-term objectives. This thoughtful approach made a real difference in the quality and relevance of the candidates presented to us. Charlie consistently demonstrated strong market knowledge, professionalism, and genuine commitment to delivering the right results rather than just filling roles quickly. The engineers we hired through this partnership have exceeded our expectations and are already making a meaningful impact within our teams, both on a technical and personal level. I truly appreciated the consultative approach and the high level of care shown throughout the process. I would gladly recommend Charlie and HartleyCo as a reliable, knowledgeable, and trusted recruitment partner.
