We've built LeaseMatrix (http://lease.io/) over the last 18 months. The stack is Linux/Apache/MySQL/Rails along with Bootstrap and Javascript. The app is a web-based alternative to a spreadsheet for commercial lease analysis and comparison. We (obviously) use Bootstrap 2.3 with very little customization, as most of our development focus has been on the backend thus far because it is heavily finance focused with many complexed calculations. We use AWS and Rackspace for hosting. Other apps we use include Stripe (love it), Intercom (love it), Optimizely (love it), Google Maps API, Google Charts API, Feedjit and Wordpress (for blog only). We've played around with integrating KISSMetrics and considered Mixpanel, but our traffic volume is such that Google Analytics + Intercom + Feedjit works well enough for now.
