IdeaHunting is a Portuguese site, but they are kind enough to also accept submissions in English. I won 400 Euros for an idea for Volkswagen and I was thrilled to receive the prize. The best thing about it, is that they celebrate each winner with a mentioning on Facebook. This lends a lot of credibility to a crowdsourcing operation – announcing winners fairly fast, fairly openly and most importantly, fairly.
Their system of reviewing ideas is very good, too. They have a moderator who they call a “Hunter” (coz their site name is IdeaHunting). S/he does a great job of giving comments on each idea entered. The site is extensive, but very easy to use. They use precise long numbers to code each submitted idea. The briefs are also very detailed and the community interacts and posts comments and clears all doubts rather well. They are not running as many live contests as they deserve. I wish more clients would come to them.
Their company name is very apt and will help them SEO wise down the road – after all, all Creative Crowdsourcing is a form of idea hunting. Their “Hunter” is kind enough to give you feedback, even if you don’t win or your idea isn’t hitting the mark. I have participated in very few contests and will do my best in every contest they put forward. I wish them the very best.
