THEN AND NOW: The first offices of the world's biggest tech companies, where billion-dollar ideas were hatched

Some of the biggest tech companies today were originally founded in garages and dorm rooms across the country.

A new set of GIFs from the Cove, an office space sharing company, morphs the "then" pictures of tech companies' humble beginnings into their new headquarters of today.

Cove made the GIFs to remind their members many companies that started small have reached great success, explains Kat Haselkorn, a member of Cove's marketing team, to Tech Insider. 

"Even when you're starting small or working remotely there's so much you can do and you can really grow into a huge global brand," she explains.

Check out what some of the world's largest companies looked like when they started out below:
