Ugh, mobile sucks trying to do anything related to this, especially with translations. If you're looking to do dd on the merging parent/sub-cos, I listed them below. These are at least the main ones for the most part. They are established, but since they are private it's going to be hard to find a whole lot. I'm pretty satisfied with the dd we have. I'm not saying quit doing dd, I'm just saying don't drive yourself crazy. The company gave us a lot of info we didn't have to do much digging for and they flat out specify their plans/projects/products.
