It's a python shop running either on a custom DB or on Berkeley DB. Their core business asset is the collaborative filtering mechanism that drives the Redux.com site.
I got the impression that the site itself is very much a proof-of-concept application of the underlying technology. They have a BHAG to become the default collaborative filtering mechanism for the internet. If they are successful, I consider it very likely that they will do so by licensing this technology to other companies.
It should also be noted that, as a company, they did not start out in the direction that they're going now. They've gone through several products and switched directions multiple times, eventually settling upon what they're developing now as a result of that process.
If I remember correctly, they are 11 employees, 8 of which are engineers and the CEO is a definite techy.
Smells like win to me.
