Informational edge, analytical edge & behavioral edge are very important for an investor to build conviction about an investing idea. However, most of my time goes into sorting through enormous amounts of source material. Needl is that one of a kind tool that allows me to sync all my relevant data sources into Feeds which 'feed' me the bite sized data points I want to cover. I can attach my personal data sets to it as well & never bother to sort or clean them in any way & Needl does contextual searching for me. It's fast, it's accurate & it also surprises sometimes by pulling relevant stuff out a pile of my own data which I otherwise wouldn't have remembered on my own.
