Our culture

Our culture is extremely important to us, it is what makes our firm truly unique, the ‘how’ we do what we do. So much so that we have explained and defined our culture in Our Way (our code of conduct) so we all remain unified in the understanding of our approach; "the why", "the what" and "the how" we do what we do from the moment we join the team.

Our Way is entwined in our people processes and is at the heart of the employee lifecycle, we attract, recruit, assess, develop and reward our people in line with their adherence to the performance and behaviours it defines. In the same way that we make markets by bridging between buyers and sellers, we bring together high calibre financial and technology specialists by providing an environment that helps cultivate innovation, promote collaboration and enables excellence to flourish.

We recognise that our culture continues to evolve as we grow, enabling us to be the best we can be in achieving our purpose. That’s why we are committed to our diversity & inclusion initiatives, we want our team to evolve to be as diverse as the client network we serve, but we have to be realistic, due to the nature of our firm this will take time. We recognise as a firm renowned for growing our own talent which prides itself on our people’s experience & long service history, it may take longer for us to authentically reach diversity targets at senior levels.

Servicing our clients' needs for more than 30 years

In 1994 our fixed income desk was launched, trading in retail size. European and North American trading followed in 1999; investment trust trading, research and corporate advisory in 2002; ETF trading in 2006 and then Winterflood Business Services WBS (our fully outsourced dealing and custody model) in 2010 - all in response to evolving demand to widen the investment universe.
