I used to (as recent as a couple months back) work at SpiderOak. Encryptr is connected to SpiderOak in a couple ways. First, it's build on top of crypton (https://crypton.io/ https://crypton.io/) which is a SpiderOak research project. Second, the dev (https://github.com/devgeeks https://github.com/devgeeks) works for SpiderOak (see his github teams or https://spideroak.com/about/team-&-leadership https://spideroak.com/about/team-&-leadership). Encryptr was a side project of his that he started in his spare time (to mess around with crypton), though obviously SpiderOak is now interested in its success (since it's one of the first/only crypton projects live in the wild). Some other notes: SpiderOak didn't surface after the Snowden leaks. It was around at the same time that dropbox started. However, the Snowden leaks did prompt a lot more interest in zero-knowledge cloud services, so if you mean "surface" as in "became more popular with the public" you're right on those lines. Also, while I'm not sure if Encryptr has been audited or not, the Crypton project itself has been at least a couple of times.
