Chua runs Singapore’s most valuable company, with a market capitalization of $46 billion. Now she is reshaping the telecom giant to become a global player in cybersecurity. She recently snapped up US-based Trustwave for $810 million, strengthening the firm’s cloud-based portfolio and giving it an edge in threat intelligence technology. Expect more such investments in growth sectors: the chartered accountant is doubling down on digital marketing, premium video, and advanced analytics. Singapore Telecommunications is known as one of the best-governed and most transparent companies in the country. —Rupali Arora
