Le Hoang Diep Thao (Lê Hoàng Diệp Thảo) is a Vietnamese businesswoman and national leader in Vietnam's coffee industry.

[6] She met her future husband Dang Le Nguyen Vu, a medical student with aspirations to start a coffee business, when answering his calls to the service.

Thao offered to financially support a new coffee business targeting the major metropolitan area of Ho Chi Minh City (Saigon) using her family's resources.

Convincing Vu to support the new line of business—which he named “G7” in reference to his ambition to penetrate the world's most developed markets[11]—Thao led Trung Nguyen to invest in production facilities and launched the brand in Vietnam at a high-profile event at the famous Reunification Palace in Ho Chi Minh City, where during a blind taste test involving 20,000 drinkers, 89 per cent said they preferred G7 over a foreign brand.

[14] G7 instant coffee became a high-performing commodity traded by the firm, selling in 60 countries around the world and achieving significant market penetration in China, South Korea and the US.

[21] In 2020, Thao was elected vice president of the Vietnam Cocoa Coffee Association for the ninth term and was awarded as Most Admired Entrepreneur in the Vietnamese Food & Beverage sector by Global Brands Magazine (UK).
