Agile idea generation and vision planning
We at Agora wholeheartedly believe in the wisdom of crowds.
We provide a framework for crowdsourcing and online collaboration where the aim is to generate ideas and form a joint vision.
The tool is developed by Agora Crowdsourcing, a non-profit based in Reykjavik, Iceland.
