Guru is very well suited for storing lots of product information. It's very easy to tag and organize your Guru cards which makes it easy sort through later. You can also assign certain people the responsibility of making sure their team's Guru cards are up to date which also keeps everything clean, organized, and updated.
Guru was difficult to learn and navigate at first, but once you get the hang of it, it is very efficient and actually makes day-to-day work a lot easier
