Bubble

The shortage of engineers, and more generally the need for employees that can program computers is one of the main challenges that companies face. That's the reason why we're building Bubble, a visual programming tool to build web apps without any code. The idea has been talked about for years, but we have a platform that is now used in production (we have customers that got into 500 Startups without writing any code, and another user cloned Twitter - notrealtwitter.com).
