Spreadd captures all the human activity across the organization, by tapping into the tools that everyone uses (gdocs, calendar, dropbox, wikis, etc.). That way, it learns what everyone is doing, keeping an always up-to-date profile of every worker. No more filling (and maintaining) endless forms at the company's directory.
But there's more. For every activity you do, Spreadd will try to match it with all the profiles - gathering the best people around the right activities at the right time.
