Kate is the dynamic founder and CEO of Diamond Logistics where she is driving growth and championing values

Kate has built one of the UK’s most forward-thinking delivery and fulfilment networks - and she’s done it with a blend of bold ambition, rock-solid values and a deep commitment to people. Under her leadership, Diamond has achieved annual turnovers of eight figures and contributed over £100 million to the UK economy in recent years. This isn’t just a story about financial growth; it’s about how vision, culture and purpose can power long-term success.

From the outset, Kate’s mission has been to transform the logistics landscape by blending technology with human connection. Through the company’s proprietary platform, Despatchlab, Diamond gives clients complete visibility, control and efficiency whether they’re fast-growing e-commerce brands, national retailers, or local businesses needing same-day courier services. But beyond the innovation, Kate places equal emphasis on the relationships behind the business.

Central to Diamond’s success is a culture of collaboration and empowerment. Kate believes in surrounding herself with capable, motivated people and then giving them the freedom to excel. She’s a strong advocate for inclusive leadership, ensuring that every voice within the organisation is valued. “Business is about people first,” she often says, reflecting her belief that happy, supported teams are the foundation of exceptional client service.

Kate also champions the idea that commercial success and social responsibility should go hand in hand. Under her guidance, Diamond has supported multiple charitable initiatives, encouraged environmental responsibility, and fostered an environment where ethical decision-making is the norm, not the exception. She’s vocal about building businesses that contribute positively to the communities they serve, rather than focusing solely on the bottom line

Her leadership style is both visionary and pragmatic - always scanning the horizon for emerging trends in logistics, yet grounded in the realities of running a business. She encourages calculated risk-taking, innovation, and resilience —qualities that have helped Diamond navigate industry challenges while continuing to grow.

For Kate, what matters most is creating a sustainable, people-centred business that can thrive for decades to come. That means keeping client trust at the heart of every decision, investing in the right technology, and never losing sight of the values that have driven Diamond from day one: integrity, service excellence and a relentless focus on improvement.

In an industry often defined by speed and competition, Kate Lester stands out for showing that success can be measured not just in pounds and parcels, but in the positive impact a business has on its people, its clients and the wider economy.
