Used a type of pre-release funding model where those who pre-order the game (fund it) during its development phase get their hands on alpha, beta, and other very early development builds as they're made.
Name variations: Early Access
The first video game about Alpha funding was released in 2011.
The only realiable thing about this funding model is that those who buy the game at the very least get a prototype if not the final game if the developer flops financially during the development phase.
Following services are known to allow/aid alpha funding: Desura, Steam, and Humble Store. Crowdsourcing also commonly employs alpha funding.
