I saw several of these attempted at Google. They never went anywhere. Probably the most public was Google Wave. Here's the problem: you can't create the same environment without the same risks and rewards. Google employees get compensated very well, better than all but the luckiest startup employees. If the "startup" fails, no biggie. You just move to another project. At the same time, the "startup" needs to retain talent so you're competing with other projects. So what happens? The "startup" creates an incentive structure that rewards mediocrity that has nothing to do with the original goals. This happened with Wave and it happened with Waymo.
