Cisco.
A web-app for developers to manage their web-apps. Yes, this is a meta application with a lot of, well, meta. The beauty of CliQr by Cisco is the ease it brings to developers. Create an application once, port it into the CliQr platform, and then have the magic ability of running, testing, and migrating across all major cloud providers. In addition to solving very complex problems, we also built an admin and super-admin layer of usability, including white-label solutions. CliQr was acquired by Cisco for $260 million.
