Hello. I am the founder of this company. I understand your skepticism. It's true that it is very difficult to build a fully general dev tool that's 1000x faster and lets you control everything entirely down the pixel level. We're not claiming that. We're claiming that for a broad range of software (esp., social, messaging, and collaborative software), we can make the development process orders of magnitude faster. You do lose some customization though.
There is precedent for something like this being possible and valuable. Mid-90s level web technology was very restrictive, but did make a whole class of online service much easier to build and deploy than what existed before that (CompuServe, etc.) You didn't have complete control over every aspect of display, networking, etc., but the loss in customization/control didn't prevent it from enabling a lot of very important and valuable projects.
