LEGO Ideas is LEGO’s crowdsourced product-development platform, originally launched as Cuusoo.
The service allows fans to submit original LEGO models and gather support from other users. Projects that reach the required support threshold can be reviewed by LEGO, which considers factors such as originality, play value, safety and licensing before deciding whether to produce an official set.
The platform began in Japan as Cuusoo through a partnership with the online crowdsourcing company Elephant Design. LEGO later expanded it internationally and renamed it LEGO Ideas. Successful projects have included fan-designed models based on subjects such as science, architecture, entertainment and nature.
A common misunderstanding is that reaching the support threshold guarantees production. It does not: LEGO’s review process is separate, and only selected projects become official sets.
