PeerReach is a tool to find the influencers in a topic, language and geographic area. But it does more than help you find them, it helps you understand their main areas of interest and influence in each one of them.
You probably thought of other tools that are stablished in the market- like Klout, PeerIndex and Kredly- that already do something similar. These competitors are focused on their ranking number and are not so good in defining the right areas of interest and influence.
When I first saw my profile in PeerReach and those of a couple friends I was impacted by the quality and relevance of their categorization.tech startup videos.
