I've bought several products in this category in the past, and the common problems with them were either the credits went too fast or the data was not that great (or not updated often enough).

However, I just spent some time testing this and I am liking it. It works well, is easy to navigate, and I have not encountered the two previous concerns I mentioned. For example, with this, the credits are not frivolously burned using intermediary steps, and two, the data seems pretty good.

To give you a rough idea of how this works: you first enter either a URL or search terms. Personally, I prefer search terms because although it can derive those from a website, you may have a specific plan in mind (say you want to focus on one aspect of your website and not the full product/service line). But either way, you will then be presented with a number of relevant search tags. Next, you select the tags you want to explore (and you can choose the number of results you want for each tag).

Lastly, you choose the target country, follower count, and if you require an email to be available (I don't, because you can usually find their contact info elsewhere regardless). At this point, the results will take a few minutes to generate. You don't have to wait around for that though, and in fact, they will email you letting you know when the results are ready. The time it takes will depend on the number of results you want, but a search for 20 influencers took maybe 2-3 minutes I think.

A few other things to note - you can create folders for projects/lists, which is handy. Your past searches are saved under a history section. Also, you are not charged for influencers that have already come up for you, since there can always be subject area overlap when it comes to influencers in general.

I have not used the bulk email function, although I am sure some will find that handy. I prefer to use my own email, since I want to send very personalized, individual emails. I know they are working on supporting your own email provider (gmail was just introduced), so if you are looking for that functionality, they will have it.

In summary - I like this product. I can see the founder is absorbing and implementing feedback - a great sign. I think the value is definitely here right now, and it is worth the price asked. If you work with influencers (or think you might), I would recommend you give this a try. These tools can be very expensive, so this is a good opportunity for you to "get in early" as they say, at a very favorable price.
