StackPath came out of nowhere. As far as I could tell at the time, they didn't have any public products. And all of a sudden they bought MaxCDN. I could never tell if it was actually an acquisition or more of a merger or something else?

Stackpath is from the founder of Softlayer. Raised private equity money and acquired several companies including MaxCDN to start a new service. The subbrands still exist but are slowly migrating and will refer you to the stackpath products.

Hi there. I'm DevRel at StackPath. We have an will continue to support the businesses that we have acquired, but the long term plan is to roll everything into a single platform under the StackPath umbrella. Our customers won't see much if any difference in service other then better performance and more features/products when we migrate them.
