Cornerstone (for SVN to store design assets / projects)
General tools: - JIRA, Confluence, HipChat (the Atlassian stack) - Google Drive / Docs / Sheets
Other tools, depending on the client: - Sketch - InVision - Marvel
The nice thing is, since our team of 50+ designers have so many clients, it's really up to our smaller teams to decide what we like best and use it, for the most part. We have a lot of flexibility in choosing our tools here, aside from storage or anything cloud-based (which does limit our options, due to security and audits).
