Former army officer Arun Kar named among UK’s Top 50 Ambitious Business Leaders for 2026

Former Indian Army officer Capt. Arun Kar (Retd.), founder of UK-based technology company Xpertnest, has been named among the LDC Top 50 Most Ambitious Business Leaders for 2026. The annual programme, organised by private equity investor LDC in partnership with The Times, recognises business leaders driving company growth and contributing to employment and economic activity. The recognition ceremony was held at BAFTA in London.

From military service to technology entrepreneurship

Kar’s move into entrepreneurship followed an unexpected turn in his military career. A medical injury forced him to leave the Army, prompting him to pursue a different professional path. He founded Xpertnest in the UK in 2016. The company provides technology services in areas such as artificial intelligence (AI), automation, analytics and digital transformation. It also has offices in Noida and Ahmedabad in India and maintains a presence in the US.


The 2026 LDC programme represents businesses with combined annual revenues of £1.4 billion and nearly 8,500 employees across 55 towns and cities in the UK. Reacting to the recognition, Kar said the principles of resilience, teamwork and mission-focused execution that he learnt during his military service continue to influence his approach to business. He also acknowledged the contribution of Xpertnest’s employees, leadership team, customers and partners to the company’s progress.
