We initially put about 5 days (2 people working almost 24 hours a day it seemed) into getting the concept from paper to a working site in time to make a deadline for a VC funding submission (which we didn't get). The crawler, ripper, indexer, DB and the website have been tweaked almost daily over the last 6 months or so. The interface is under a re-design and so is most of the back-end (crawling needs to be done better, uploading to S3). It all runs on 2 linux machines and ripped data is stored on Amazon's S3 service. So-far the only money that we put into it ourselves is $20 for a logo off ebay that we're not even using and the S3 charges, which are about $20/mo at this point. Other hardware and bandwidth is just our own personal machines and internet connections, so that's 'free'. :) We don't have any investors.

How much money/time did you sink into this, and do you have investors yet?
