Data is like a “seed” for social problem solving, new business models, and technology research including artificial intelligence. We create a location-based data trading platform ‘Cada’ that gathers these seeds that cannot bloom. ‘Cada’ turns them into new opportunities. 'Cada' is a data market where subjects who need data can open a data collection project, and the public can easily acquire data through it and trade it fairly. Up to now, over the 17,000 users have legitimately traded the data that they easily acquire in their daily lives, creating new research and business opportunities for more than 10 companies. Paprika Data Lab Inc. is doing its best to achieve the goal of creating the largest living lab data pool by gathering all the location-based data that is overlooked in daily life more easily in one place.
