Great British Billion-Pound Businesses
Foreword
James Whittaker
Head of UK wealth management, UK CEO, Deutsche Bank
We are living through challenging times and there is a lot for our clients to process, whether they are investors or active entrepreneurs. The rise of interest rates, the changing geopolitical situation and a new government are just some of the factors leading our clients to adjust their approach, alongside the impact of technological advances. The business leaders in this list have demonstrated an ability to navigate testing times and continual changes to build impressive and lasting legacies.
Having spent the majority of my career working with entrepreneurs, including some on this list, it has been a privilege to have a ringside seat to see their energy and creativity as they realise their vision for their companies. As in their businesses, it’s important that business leaders choose the right advisers for their wealth. It can be easy to forget the emotions at stake when you’re working with people who built their businesses from scratch.
Deutsche Bank is proud to have been acknowledged by Euromoney as the World’s Best Bank for Entrepreneurs. Supporting entrepreneurs has always been a core part of our DNA. Historically, that’s been a keystone of our business, starting in Germany where we were facilitating international trade. But it’s become a focus and point of pride for the Private Bank to work with entrepreneurs in a very holistic way. That means looking at their life goals broadly, what they want for their businesses and their families, and what mark they would like to make on the world.
