Y Combinator hosted 52 demos at the end of March. "Demo day" means that new software and hardware startups get to show off what they do in a brief demo to potential investors and the world, and hopefully get further funding.
Two of them related to CAD. Here are the synopses quoted from TechCrunch at https://techcrunch.com/2017/03/20/yc-demo-day-winter-2017/.

It uses Peek, a revolutionary plastic it says is as strong as metal. It’s already shipped 33 printers and booked $450,000 in revenue with 60 percent margins.
Pantheon Interactive VR Development
Pantheon has built a VR game creation tool where you can pull in shapes, sculpt them to your liking, add textures to create a VR world, then drag-and-drop in simple game mechanics. Creators can then instantly publish their VR game to the Pantheon platform, which is hoping to become the central hub for casual VR games by amassing a ton of titles.
