I recognized their name from Packer.io, for which there is a DigitalOcean-specific builder: http://www.packer.io/docs/builders/digitalocean.html.

Given that it's a fairly new project and DigitalOcean is a relatively unknown cloud (relative to EC2 the other cloud-based builder in Packer.io), I wondered if they had also perhaps contributed heavily to the project. That's another good way to see a sharp rise in popularity from developers!
