From the snow-capped peaks of Davos to the academic halls of Oxford, Arun Kar’s career has crossed borders and sectors, blending military discipline with modern entrepreneurship. Born in Odisha, India, Kar’s journey began in the Indian Army, where he served until an injury ended his military career. That experience, he has said, instilled values that now shape his ventures in technology and sustainability.
At the World Economic Forum 2026, Kar took part in a CNBC session focused on responsible innovation. He argued that technology must solve real problems before chasing profits. “Trust comes first,” he told the audience, a sentiment that aligns with global conversations about ethical AI and inclusive growth. His remarks drew attention from investors and policymakers alike.

His work extends beyond policy discussions. In 2025, Kar received the UN Global Excellence Award at Oxford, where he spoke about leadership transitions from the military to global business. The event brought together scientists, doctors, and business leaders, all interested in how enterprise can drive change. His focus on scale, capital, and influence reflects a growing trend in corporate responsibility.
Xpertnest, the technology company he founded, has grown without external funding. By 2025, it had reached a valuation over USD 100 million, verified by SEBI-registered banks and UK-based analysts. The firm’s growth rate—220% in one year—placed it among the UK’s 500 fastest-growing companies. A separate index later listed it in the top 200 firms, according to data from Professor Dylan Jones-Evans’ UK Fast Growth Index.
Parallel to his tech ventures, Kar founded Earthnest, a sustainability initiative targeting plastic pollution. The company’s focus on biodegradable materials and circular economies aligns with UN Sustainable Development Goals. Investors and analysts note the rising importance of environmental strategies in corporate planning, a shift Kar has helped accelerate.

Kar’s work isn’t limited to boardrooms. In Odisha, he collaborated with the UK Odia diaspora to build a sanitation facility for tribal girls at a government-run ashram. The project addressed long-standing issues of health and dignity. He also holds a Guinness World Record for participating in the Vitality Marathon to support UNICEF’s polio vaccination efforts in 2021.
Industry estimates place Kar’s net worth at around USD 145 million, drawn from tech, sustainability, and real estate. His ventures span continents, yet his focus remains on solving problems—whether through AI, infrastructure, or public health. The numbers tell one story: growth. But his work suggests another, one centered on trust and impact.

At Davos, Oxford, and in Odisha, Kar’s presence shows a shift in how business leaders approach their roles. The metrics are clear: Xpertnest’s valuation, Earthnest’s environmental goals, and the sanitation project’s impact. Yet the message, he insists, is simpler. “Innovation must serve people first,” he said in an interview last year. “That’s how trust is built.”
His story, like his ventures, is a blend of discipline and vision. The military taught him resilience. Business gave him scale. And the world, he says, has started listening. Whether in policy forums or tribal villages, the same principle holds: solving problems comes before profit. That, at least, seems to be working.
