PaperC is a platform for reading books online. After reading a page of a book online for free you can buy it for 5 cents and add citations and comments, download it as PDF etc. We bootstrapped their website including PDF processing and download infrastructure, payment gateways and publisher backend within three weeks coaching their programmers in agile and test driven development at the same time.

DoingText helps you to work on any kind of text together: Marketing concepts, articles for a magazine, project plans, group assignments, scientific papers, an invitation text… you name it!

HouseTrip is a market place for short term rentals. Together with HousTrip’s people one pair of upstram programmers built the site within 3 months.
People can rent (out) rooms, apartments or houses from/to other users. The extensive profiles, reviews and comment walls allow you to get to know the place you are about to rent in advance. With the built-in auctions you migh be able to snatch a bargain. The site also spots a complex property management system for hosts.
