10. Microsoft Research Lab

Microsoft’s research arm is focused on computational theory, AI, machine learning, networking, security… the list goes on. Perhaps almost as impressive is the geographical reach. The original (and still functioning) lab is at HQ (Redmond, WA/US) but it also has labs in Cambridge (UK), Beijing (China), Bengaluru (India), Santa Barbara (CA/US), Cambridge (MA/US), New York (NY/US) and Montreal (Canada).
