Now in its 46th year, the non-profit forum - which most people just refer to as Davos - features the motto "Committed to improving the state of the world," and it's attracting more high-profile attendees than ever.

Over the course of the week, celebrities, politicians, and high-profile executives give talks to champion causes important to them while also taking meetings and networking. In the evening, there's parties to attend.

With many choosing to arrive and depart Davos in style, private jets and celebrity sightings are commonplace.

Here's some of the famous actors, tech execs, world leaders, and billionaires who attended Davos this year.
