Datum Interviews

Take Control of Your Data with Datum

"Datum is taking the power of data back to the users who create all that wonderful selling points that companies like Google, Facebook and the like take advantage of without offering your any monetization possibilities. They make money off your data while you get nothing in return. Its really a backwards system and Datum is looking to help put that power back in the hands of the people." – Tijo of Arcane Bear

C2B2B: Enrich Bluetooth Beacon Data with Consumers' Data

Company B with Bluetooth beacons installed in retail stores creates billions of data points every day. They are interested in purchasing shoppers' location data from their phones to enrich their in-store data with behaviors before and after the visit. With the user's permission, the Datum App extracts users' location data, securely anonymizes it and makes it available through the Datum Marketplace. Company B can now enrich their existing data set with this new data and re-sell the new, more valuable data back onto the Datum Marketplace. Proceeds of the enriched data sale are shared back to the original consumer data owners as well as Company B who added value to the data.

Telecom Company Selling Smart Home Kits and Unsure How to Unlock Data Value

Large telecom Company T sold smart home kits to over 1M households in 2017, but smart home is not their core business. Now they have mountains of data from the smart home gateways of all the homes, but they do not know how to unlock the value that lies in this data. By uploading data sets to the Datum marketplace they can gauge interest in the data and find customers who are interested to buy this data.

Marketers Looking for People Interested in Electric Vehicles in London

With the users's permission, the Datum App collects social media likes and preferences and aggregates the information into lookalike audiences that marketers can buy.

Mobilizing Communities To Collect Data

The right mix of fertilizers specific to a region and crop can be the difference between feast or famine. Poor farmers in developing countries can not afford to pay for soil analysis on their own. Several NGOs already provide free fertilizer mix analysis but they need data. Using the Datum App, people are incentivized to enter soil sample measurements and make it available for NGOs to process. The resulting fertilizer mix ratios are shared back with the farmers who can use it to boost production.


At Datum we have one focus - Creating a viable data marketplace to start returning value to token holders in the shortest time possible.
