Datathon d

This was What datathon 2017!

On April 22-23, 2017 we invited all data enthusiasts to come down to central Amsterdam to apply their knowledge, challenge themselves and gain new skills!! As a pre-event to WHAT – The Behavioral Data Conference, the datathon aimed to fuel new thinking in analyzing behavioral data and impact the consumer insights industry. The participants had 24 hours to create the coolest model, visualization, or insight in order to better understand online behavior.

A huge ‘Thank you’ to everybody who attended and contributed in making this event amazing! You can find the recap to have a look back on the event and see some of the impressions of the day here.
