"Arne from World4Brains proved to be not only a great inspiration for my new start up venture, but a reliable and efficient business man who knew exactly what he was talking about from past experience.  He took the time to provide me with prompt follow ups after sending through his initial advice. He has such a positive enthusiastic attitude which gives the new business man a proud boost in confidence.  World4Brains is a great, fast, effective tool.  I have no hesitation in recommending  Arne for your next project".
- Tania, Australia


"I posted a small project with a very small budget on World4Brains, seeking creative feedback on how to market my business offering- an innovative approach that helps companies turn themselves around. I found the feedback to be of an excellent quality and helpful in clarifying my thinking. In fact it led me to proceed in an entirely new direction!

Arne Klingenberg, the creator of the concept, is very hands-on, and was extremely generous with his time and insights over the course of the project. Without reservations I can recommend World4Brains to any individual or organization looking for intelligent, creative, innovative thinking at a very economical price."
- John Berling Hardy (

"I used World4Brains to develop strategies for raising seed funding our our organization. Over the course of two weeks - we had dozens of innovative solutions. I also saw direct traffic to my site from World4Brains consultants trying to find out more about my organization before submitting their ideas. Many suggestions were initially put forward by one person but then built upon by other consultants to make it even better. A combination of these ideas will be used.

I would not hesitate to use the service again and would suggest that any organization (of any size) could benefit greatly by tapping into this vast pool of experience and brains. I am happy to discuss in more specifics the World4Brains service and ideas received with those who want more detailed information."
- Roii Patterson, co-founder (


"We tried World4Brains recently to get ideas for a marketing campaign, we found the site easy to use and received a multitude of ideas from their consultants. World4Brains were professional and very helpful throughout the entire process."
- Dominique Wright, Marketing Manager, - Business software for control freaks

"I was delighted to be selected a winner on my first project on World4Brains. The client, Mr. Jonas appreciated the ideas submitted in the Consulting Project for his business and Arne of World4Brains provided prompt support for all queries. After the Consulting Project ended I was glad to get more work from Mr. Jonas directly. I am looking forward to participating in many more projects on World4Brains. The Crowdsourcing Industry needs many more such sites which are genuine and listen to participants' queries."

"I am very happy to be one of winners of the project! By the way, I think you have built a great online service for people from all around the world to share and use each other's knowledge and expertise. Really unique place. Experience from so many fields, clear rewarding and payment rules, open-minded problem solving discussion (for both well defined problems as well as the ones that needs more definition and clarification during the problem solving process itself)! Great work."
- Jakub Grabowski,


"Arne, I just wanted to let you know how pleased I was to have been accepted as one of the winners of the Sybiz project and to thank you for your help in posting my last minute comments from the airport! It was great to be able to share my experiences and even better to be able to view and learn from the inputs of the other consultants. From a consultants view, it was an easy to use and professional process from the posting point to receiving payment which in other companies has not always been my experience. I believe your web-site has a “winning” formula so I am looking forward to being able to further contribute. Thanks again for making this happen. Regards,"
- Peter, Talkcents
