Hannah Mann and Abigail Stuart, Co-Founders of Day One Strategy, have been recognised in The LDC Top 50 Most Ambitious Business Leaders for 2026.
The prestigious programme was created by private equity investor LDC, part of Lloyds Banking Group (NYSE: LYG), in partnership with The Times, and has celebrated exceptional entrepreneurs since 2018.
This year’s edition attracted more than 620 nominations from across the United Kingdom, reflecting the breadth of ambition among leaders building businesses in every region and sector.
The 50 leaders featured are expanding internationally, developing new products and services, challenging established markets, and investing in their workforces to drive sustainable growth.
Together, the businesses represented generate £1.4 billion in annual revenues and employ almost 8,500 people across 55 towns and cities throughout the UK.
Day One Strategy is a global healthcare insight and strategy agency that works with eight of the world’s ten leading pharmaceutical companies, combining human expertise with purpose-built AI decision tools.
Founded in 2019, the business has grown rapidly across the UK and US, helping healthcare leaders launch stronger, grow faster, and lead their respective markets with greater speed and clarity.
Hannah Mann commented on the recognition, saying: “From the start, we set ourselves ambitious goals. We wanted to build a global company that the best people wanted to work with and work for.”
Mann added: “We even had a picture of Mount Everest as a reminder of the journey ahead. That ambition pushed us to make bold decisions and take risks, and today we’re proud to work with eight of the world’s ten leading pharmaceutical companies.”
John Garner, Managing Partner at LDC, praised the cohort, stating: “What stands out about this year’s LDC Top 50 is not only what these leaders have already achieved, but their determination to keep moving forward.”
Garner continued: “Across the UK, they are finding new opportunities, investing in their people and building for the future. I congratulate every leader featured this year and wish them continued success.”
Day One Strategy’s proprietary AI decision engine, InsightBrain, supports brand teams from early opportunity assessment through to performance tracking, underpinning the agency’s rapid expansion on both sides of the Atlantic.
LDC has partnered with hundreds of medium-sized companies across a wide range of sectors throughout the UK, positioning itself as a key driver of growth among ambitious management teams nationally.
