The 2018 Fortune 40 Under 40 list has been released with Instagram cofounder Kevin Systrom having knocked French leader Emmanuel Macron off of the top spot.

Trends come and go quicker than ever in the digital world, but photo-sharing social network Instagram remains one of the world’s most popular apps almost eight years on from its release. This year, the app has crossed the one billion user mark and has amassed a value of more than $100bn.

With a safe pair of hands at the helm in Systrom, the Facebook-owned company is going from strength to strength.

Systrom is joined on the 40-person list (there’s actually 54 individuals in total) this year by 34 new entries, all of which will be hopeful of dethroning Systrom in future years.

From billionaire tech founders to culinary creatives, here are the fresh faces on Fortune’s annual list:
