For what it's worth, you can score up to 5000 users per month completely free with Sift Science. So if you run a small site, there's no fee. If you run a large site, you can see for yourself whether we're saving you enough money to justify the price.

In addition, there are discounts from high volume, for pre-payment, and there's the possibility of scoring only high-risk users. If you run a web site, feel free to shoot me an e-mail at [email protected], and we can figure out how to make it work for you.

Just to clarify, we charge 10 cents per unique user that you query in a month, not per query. So, you can query the same user as many times as you like in a month and the cost will not exceed 10 cents for that user.
