Vast majority of people living in Australia have very useful items in their home. These items often find themselves being thrown in the rubbish bin or donated to large charities, which are often stocked with loads of inventory, selling it at an under-valued price. Meanwhile, a huge market exists whereby people are willing to buy useful second-hand items online, but cannot find them due to a lack of supply or inefficient marketplaces. charityBay is a non-for-profit organisation delivering an online marketplace that will provide a means for Australians nationwide to sell their unwanted useful belongings, and automatically direct the proceeds to their selected charity. Not only we are providing a means of helping those in need, but also providing belongings to buyers who need them. By finding these items a new home, we are increasing its lifespan and reducing hard waste. The act of giving is further incentivised by official taxable recognition for those donations in Australia, as well as our rewards program instantly claimable for donors and buyers.
