We recently built and launched CashOffersFast.com. It gives people an easy, no-risk way to put their home up for sale. Pre-qualified investors can then make anonymous bids on any home listed with the site.
We worked very closely with the owner of the site to convert his concept into a working web application. From the initial concept, we identified the minimal set of features necessary for the site to function, then took an iterative approach to quickly deliver those features. This allowed the owner to use our working copy for presenting the site to potential investors while we were in the middle of the development cycle.
The site is built in Django and was designed by Derek at ashwebmedia.
