It's the project creator's responsibility to complete their project. Grouphunt is not involved in the development of the projects themselves, neither is the platform we place the group order on.
Platforms like Kickstarter and Indiegogo do not guarantee projects or investigate a creator's ability to complete their project. As such, we've made sure to highlight this if the Grouphunt is for a crowdfunded product.
While we do engage due diligence before running a hunt, backers ultimately decide the validity and worthiness of a project by whether they decide to join the hunt and fund it. In a few cases the community has suggested the implausiblity of a product which has resulted in us not taking the risk of running the hunt.
