IBM

IBM brings together an amazing array of technology as the basis of real, practical solutions that power Earth's commerce. Some people still think of IBM as "that mainframe company," but today's IBM has been transformed into an agile, leading-edge technology creator. As an IBMer, it is amazing to be able to pick up the phone and chat with the very people who are creating and shaping tomorrow. Blockchain, quantum computing, cognitive computing, and countless other technologies are real-world here. Yes, we still sell some big iron, but (surprise!) it runs Linux!

No way to hide it -- IBM is a big enterprise, with nearly a half million employees around the world. It isn't a startup!
