This product is incredible. Our process used to be to download lead lists from a data provider (similar to Zoom info) where we would set parameters and then mine leads through outbound outreach. It was a very frustrating process as we couldn't ever seem to set the right parameters and the returns we got were extremely low. Then we tried to go manually using a combination of Sales Nav and data enrichment and that was laboriously manual. This tool is the perfect balance that allows me to identify my ICP and then hone in on the companies and personas that are most relevant to our product. Like the title of my review states - it's the missing link to our lead gen woes. The data we collect is clean and, even though I am dealing with smaller organizations, I still get a return of more than half my searches (which, if you've done this long enough, you know that that is great!). I'm still getting used to the product, but support has been great and the functionality is superb. I'm pulling for these guys to do great things. Highly recommend ZeroIn.
