The problem with most cam companies is that only a few have the ability to make the billets in-house. Crower, Isky and Crane have this ability, while the other cam companies like Comp, Schneider, Clay Smith, Reed, Lunati, Ultradyne and all the others can only finish grind the cores once they are provided to them by you or from a supplier. So that goes back to having a blank cam core to provide them to be able to grind it. I went from A to Z back when Crane folded up and found a lot of this out, some of it I already knew from my years being affiliated with Crower and Crane and a few others. But what it really showed me was how few cam companies really had this ability to do it, and most of these other cam companies are just grinders/regrinders.
