Here is a quick rundown of the tools that we use to collaborate and win at efficiency.

Company wide for Collaboration and Productivity

  • Asana for task management, planning, full replacement for internal email
  • Gmail for email
  • Google docs for sheets, word, powerpoint (supplemented by MS office for a few computers if you need to collaborate with lawyers etc)
  • Slack for real-time chatting, channel for each project
  • Expensify - simplify expense receipt filing
  • Xero - Web accounting system, that will scale normally up to ~10m of revenue, or maybe more.
