Here On Biz, a free app, lets you see where LinkedIn connections are and send them text messages, reports Inc.com. You can also use it to check into events. You can see how many of your LinkedIn connections are using the app, as well as people near you using it who aren’t yet connections. One tap and you can request a connection. Don’t worry—it doesn’t give out your precise address or venue, just that you’re in the area.
The app’s algorithm knows where you are, who you know (based on your LinkedIn connections), what industry you work in, job titles similar to yours, and where you went to college. It connects professionals based on those attributes.
