Great resource for quickly looking up information about ventures. Incredibly handy for angel investors, comparing competitors, and tracking executive movements. When combined with AngelList and LinkedIN you're pretty much all set.
I LOVE Evernote. It started off slow, but now I use it for everything, across all of my devices. I have outsourced my entire brain to Evernote at this point. The new stacks and reminders have really made it even more useful. Great tool
