Evan Spiegel (left) and Bobby Murphy (right) co-founded Snapchat, an app for sharing photos and videos that disappear in 24 hours. They weren’t even 30 years old when they had already made more than $2.7 billion each.

Murphy is married to his Stanford university classmate Kelsey Bateman. In 2017, Spiegel married Miranda Kerr, one of the highest-paid models in the world. By the way, she’s 7 years older than Evan. In 2018, she gave birth to a boy whose name is Hart. In March 2019, mass media informed the world that the couple is expecting their second baby.
