Meet the Builder behind DPI

From the Battlefield to the Boardroom: Engineering the Future of Business

Ben Legg is an engineer and builder at heart. From building infrastructure in the Bosnian war, to leading a systematic turnover of Coca-Cola India, to designing Google’s monetisation engine, his career has one through-line: breaking down complex problems and rebuilding them into scalable, high-performance systems.

Today, through Digital People International, Ben applies this engineering mindset to help leaders and investors navigate a fast-changing digital world. His work spans two key areas: Proprietary Investment Advisory and High-Impact Keynote Speaking - both grounded in unique insights, rigorous analysis and real-world operational experience.

Decoding Technologies for Investors

Ben supports institutional investors, hedge funds and private equity firms by decoding the technologies shaping the global economy. He goes beyond conventional market analysis - opening the black boxes of AI, search, social media, e-commerce and digital advertising to forecast revenue, outline risks and predict winners and losers. His expertise is very hands-on: Ben has built and run multi-billion-dollar ad ecosystems and led PE-backed technology scale-ups across the US, Europe and Asia.

Battle-Tested Leadership for a Rapidly Changing World

Ben’s leadership insights come from genuine “war zone to boardroom” experience - from ending the Siege of Sarajevo, to McKinsey strategy consultant, to turning around Coca-Cola India, to COO of Google Europe, to PE-backed CEO roles in global tech. His keynotes and executive sessions help CEOs, CMOs, and boards rethink business models, lead through disruption, incorporate artificial intelligence (AI) into org design and make confident decisions in high-stakes environments.

Building the Future of Work

Always the entrepreneur, Ben continues to build new ecosystems. In 2020, he co-founded The Portfolio Collective (TPC), the world's leading collective of portfolio professionals, reinventing the future of work, and in 2022 he launched The Chief of Staff Collective (CoSC). He also teaches at Oxford University and mentors executive teams and boards. Across every role, Ben is committed to equipping the next generation of leaders to build future-proof businesses and meaningful careers.
