Many companies think that machine learning techniques are reserved for the big guys only - wrong! I have some interesting cases, where a special offer is presented to chosen clients basing on multiple variables and patterns, and this approach makes some nice dollar each day. Another example - an anti-fraud system working in a quite niche domain, saving about thousand dollars each day.. Real fun starts when you look at your data from a different perspective,and most times it is worth the hassle!

Many times a simple logistic regression or SVM could do wonders, especially on datasets <100K examples. It's a matter of being aware such applications are possible. The code is usually less than a couple hundred lines, but takes some experimentation to get it right.
