The Devil Is In The Data.


For as long as we have had mobile devices in our pockets, people like Stephen Caffrey have been working on how to best penetrate them and use this technology to delivery highly targeted and frequent advertising.

Gone are the days of billboards and posters. What was once a blind leap into generic advertising such as location or content placement, companies like Display.IO can use the data we give to apps and websites to tell them as much about us as possible.

“We’re not reinventing the wheel with advertising,” explains Caffrey. “The thing we do differently is 1st party data. We share data, gender, age, other apps, and use this data to advertise to the user.”

It is a lucrative business. According to a report by Techcrunch, the average person is using 9 apps a day, and approximately 30 per month. This means a lot of companies have direct access to much of your behavioural habits. “When you download an app on to your device, you are giving the developer access to the interactions with that device. This is done anonymously and securely.”

Today, Display.IO is valued at $10 million after receiving a $1 million seed round from angel investors from the advertising sector. In only three years, the company is turning a profit and preparing for offices in Beijing and China – where its clients are providing access to data of approximately 500 million people.

“How can I better understand who the user is before I offer them adverts? There is a huge amount of data,” Caffrey states. It is long-known that companies gather all our individual data, and now they have discovered how to monetise and benefit from our actions. Before we know it, they will be selling us things we didn’t even know we needed.

The days of the billboards are dead. Adverts are moving from public spaces and generic magazines into the intricate movements within our intimate devices. Our phones, our lives, hold the key for advertisers. Let’s hope they like what they see, and you buy what you see.
