Leonardo DiCaprio

In October, DiCaprio became the latest investor -- and adviser -- to Israeli photo sharing app Mobli.

DiCaprio participated in the company's $4 million Series A round in his first tech investment.

The app lets users share videos and photos through subject-based channels in real-time. For example, if you were at a concert but had bad seats, you could use the app to get a different angle of the stage based on other users' uploads of the venue.

The app attracts more than 10,000 users a day, and is available on iOS, Android and BlackBerry. Besides DiCaprio, other celebrity users include Paris Hilton and David Arquette.
