CEO of Jungle Disk here, we spun out in Jan of 2016 from Rackspace. Reason they sold Jungle Disk is they're focusing on data center based apps sold to mid-market and enterprise buyers. Jungle Disk was a SMB data backup and online storage service for laptops, desktops, and servers (either on premise or cloud). Not a fit in the core sales and marketing machine inside Rackspace. My 2 cents on why for Mailgun? It is a developer focused service and while Mailgun may have customer overlap with Rackspace's overall base it is a different decision maker / buyer inside the company than the person who's choosing where to host the IT system or website, etc. So while you may have customer overlap you don't have sales and marketing buyer overlap.
