Startup idea: Amazon S3 / CloudFront cost distributor
Right now Amazon charges $0.15 / GB of Amazon CloudFront data transfer. However, if you do a higher volume, it gets progressively cheaper, until at over 1000 TB, you are only charged $0.03 / GB.
Someone should create a competitive CDN that sells premium bandwidth for say, $0.05 / GB, dramatically undercutting everyone in the business by a huge margin.
How would one or two co-founders possibly compete with Amazon CloudFront in quality and price? The backend would actually be Amazon CloudFront! Since you would rapidly exceed the 1000 TB amount, you'd be able to pass the savings onto your customers.
To be 100% sure that you make a profit, you could wait until you get enough people to pledge to switch to your service before launching for it to become profitable from day 1.
