Their business model is pooling small orders and sending them to board fabs in europe, mainly germany and some in the east.
For higher-end board that seems likely. For cheap hobby-grade boards just the job fee[1] is more than 10 boards delivered is from JLCPCB.
That said, thanks for reminding me. Will definitely compare next time I need boards.

Just checked myself using a board I already had manufactured, and can confirm it's a lot higher than JLCPCB or PCBWay.
Maybe for rapid prototyping it is okay, but at scale, to make one board is more than the entire selling point of the whole device.
Express service adds ~20 EUR, roughly the same cost as picking DHL express delivery on JLCPCB.
On top of that they also offer 3D printing, CNC machining, sheet metal bending, and even a McMaster-Carr-like parts store. It is literally a one-stop-shop for all your hardware prototype needs.
