Challenge Overview

Welcome to the DMH DATA INSIGHTS Ideation Challenge Series. We are launching two parallel tracks looking for meaningful business insights, one with client only data, and one with client data + public data. You can participate in one or both but you need to register and submit to each respectively. Please ensure you are viewing and uploading to the correct one. 

Track 1 - Client Only Data:

Track 2 - Client Data + Public Data:


In this particular challenge, DMH DATA INSIGHTS - TRACK 1,  we seek creative analysis based on the provided HEOS activation dataset

Dataset Description

A new dataset can be downloaded hereOn this new dataset, the client runs a new query in their database. Therefore, the IP addresses might be refreshed. The missing Macs could have been removed by the engineering team but for the most part everything should be the same. The major differences are: (1) More data has been added. The original data was up to September the latest is run through December; and (2) Email addresses are anonymized based on full email addresses. Therefore, please consider to use this new dataset, although the previous version is also good.

In the provided dataset (that can be downloaded here), there is connection information like MAC address and IP address, location information like zip code and GPS coordinates, product models, and registration information like activation date.

HEOS by Denon product descriptions are available here.

Some ideas on what “meaningful business insights” from the Goals section above, could be (but not limited to) are:

- Can we market to these people differently?

D+M Group, known for their premiere audio/video brands such as Denon, Marantz, and Boston Acoustics launched HEOS by Denon in June of 2014. The HEOS by Denon audio system is a wireless music system that allows you to control all your music effortlessly from anywhere in your home whether listening to different songs in each room, or listening to the same song in  all rooms.

Since its launch, HEOS has expanded the product line to what is now the complete HEOS system consisting of four speakers - HEOS 1, HEOS 3, HEOS 5, HEOS 7. It also includes the HEOS Amp, HEOS Link pre-amp, HEOS Extend Wi-Fi range extender, HEOS Drive multi-zone amplifier and HEOS HomeCinema soundbar with wireless subwoofer. In a fast-paced tech-savvy world of streaming music, mobile applications, and consumers on the go, the HEOS by Denon system has quickly become a relevant and vital brand in the D+M Group product offering. The D+M Group will continue to expand the brand and grow market share globally as it competes with Bose and Sonos. 

The HEOS brand is unique in that every unit is a true IoT (internet of things) device.  This allows D+M to collect product usage information, some consumer listening habits, and geographies where the products are used.  In this challenge, we are sharing 200,000+ lines of HEOS device activation data from around the world.  The question is:  What can we learn from this data set that could enhance and benefit the business value of this product for the D+M Group?
