Has anyone considered a SCRUM funding model? i.e. Similar to how Patreon's used to fund ongoing deliverables from YouTube artists (among others) the team could have patrons sign up to pay a smaller amount on a fortnightly basis, with the development team announcing their goal for that sprint, then taking funding on delivery. This gives patrons the option to back out further down the project if things go off course/change, thus reducing risk in committing to a failing project, whilst allowing other patrons to sign up down the line as the project starts to look increasingly feasible. Optionally small awards could be given per pledge, whilst larger rewards (e.g. your own phone) given to those who've given a certain amount by the end of the project / the pledged amounts could be discounted from the resulting phone's price.
