I actually am looking for a lead finding tool for a while, and this 1 might be it.
I am looking forward to Chrome extension and to see how well that works before buying.
Personally, I am looking for a tool like mailhunt where I enter the domain name and get the data that way, more often than not I know what leads I'm looking for, whereas this tool as we know, is for those who don't know what they are looking for exactly.
So, I think it could be a bit of both.

For example, I would love to have a feature where I enter a domain name, or a company name for that matter, and it gives all the filters it has on that company like job titles, different departments and so on.
A bit of diversity would be nice, because it's good to have a business to business functionality but also it is good to have the functionality when you know what you're targeting exactly.
A Chrome extension I believe will bring functionality a bit closer, but also it would be nice to have that on the website itself.

where is the login button???

If you ask me, the basics are there, but they are only basics, and I will track this deal a bit more, as it goes along.

But as I said, for me, personally, I need more like mailhunt experience, will you be able to provide that in the future?
