This looks like it has a long way to go before it is usable. Clicking 'Capabilities' largely just gives me the 7 day turn spiel again, while I'd expect something about min trace / space, HDI capabilities, number of layers, any fancy laminates, etc. For assembly I'd need to know more about min pitch / package size, available types of solder paste, etc. If you're doing PCB sourcing AND assembly (like it sounds like in the text here), that is not clear on the site.

Also, for slow old industries (like Automotive), you'd likely need a fast way to coordinate NDAs just to get an engineer to be allowed to share the design files with you.
