As a norm People Aggregators simply aggregate information found on the web into one profile or place. However some do way more than just that, and in this post , we will tell you about a few.
Hiretual for example when you are on Github uses advanced AI to grade a persons code. On Linkedin it lets you know if they might be looking, their salary and more.
WhoKnows not only aggregates but will give you a a graph breakdown of their expertise, experience and Education and much more.
Engage Talent lets you know how likely they are to engage with you, how they compare with others in the industry, salary and bonus info.
Seekout not only does the aggregating thing but also can provide insights with regards to companies, people, location and more. For example You can ask for insight on Nurses working for Kaiser Permanente and it will tell you how many, what locations, other companies, schools and much much more.
Of course there are also plenty of others and new ones such as Amazing Hiring, Human Predictions, and Deepsense.
The key here is to always get as much as you can from any tools and these tools that give you more are pure gold.
