Story behind Gandalf

We are product-oriented fintech team. Almost all projects we created needed a decision engine that reduces business risks. And all solutions we could find is hard to use and maintain, or very expensive. So we decided to create free open-source alternative, that is scalable, reliable and flexible enough to cover 95% of cases.
We decided to use open-source database MongoDB that have good scaling capabilities to make it suitable for Big Data.
Also we believe that vendor-lock is a bad thing, so we published all source code under a GPL license, feel free to change it as you wish.
