In 2003, iReuse CEO Ken Kurtzig asked Monsoon to help build an online community that would help businesses donate unwanted materials and furnitue to nonprofits who could use them. Businesses would be able to sustainably dispose of extra materials and collect a tax write-off, while nonprofits would get free or inexpensive stuff. iReuse required an intuitive front-end combined with a sophisticated back-end matching system to connect businesses (“sellers”) with non-profits (“buyers”). Key components of the matching process would be the proximity of prospective buyers to sellers, and need. Monsoon created a complete web application to serve the needs of the iReuse community. Comparable to eBay or Craigslist in scope, we built iReuse.com on a sophisticated set of platforms: an online marketplace for individuals to sell, donate, buy, or take what they needed; a wishlist feature that allows organizations to communicate their needs; and a tool for larger corporations to reallocate their own resources. The main power of the software is an algorithm that connects the needs of non-profits with corporate overstock. The algorithm matches organizations, checks for proximity, and factors in each organization’s need. The app then facilitates the meetup, transaction, and delivery. Successful web applications evolve quickly and often. iReuse has worked with Monsoon for more than four years, and the website has continusously evolved as our team gains a stronger understanding of what their clients need. Built entirely on a .NET platform, Monsoon worked with iReuse through several versions and continues to support the interface as the company grows.
