Trevolta is a crowd-funded website focusing solely on travel. The goal of the site is to enable travellers to submit their extraordinary ideas for expeditions in order to raise funds for it. Projects can be backed up by inspired people or sponsors looking for marketing opportunities and brand awareness. Think Kickstarter, but for travelling. Currently, access to Trevolta is private and given in batches. Batch 1 is in progress now. Sign up and claim your spot in the queue to join the next batch!
