I'm working on http://algorithmic.ly -- algorithms as a service.
It's cool because I get to help startups who don't always have the resources to hire someone like me who specialized in implementing and scaling certain kinds of algorithmic features. These startups need help with everything from geospatial search up to anomaly detection and predictive analytics.
It's bootstrapped, so while I'd love it if it was a public offering, at this point it's still a hybrid consulting/data-services company. Eventually it will be a public platform, and I hope we can help a lot more people!
