100 Product Managers Who Changed the World · #25: Travis Kalanick

A year later there was UberCab: press a button on your phone, watch a car drive toward you on a map, and get out without reaching for your wallet. The man who built it, Travis Kalanick, was pushed out by investors in 2017 and came back in September 2026 with a robotics company. #25 of the 100 product managers who changed the world, scores 92/88/80/90/95/95.

100 Product Managers Who Changed the World · #20: Brian Chesky

In October 2007 two design-school graduates who couldn't make rent put air mattresses on their San Francisco living-room floor and charged guests $80 each. In 2025 Airbnb made $12.2 billion in revenue. The man who built it is Brian Chesky: son of two social workers, trained in industrial design, once sold election-themed cereal at $40 a box, and in 2023 said Airbnb had got rid of the classic product management function. No. 20 of the 100 product managers who changed the world, six dimensions 92/95/95/90/89/93.
