Data is the most valuable asset in the world.

Every time you work on a political campaign, half the people hate you. That's how it is.

In order to create predictive algorithms, you need to have a training set. So, that training set is created through our quantitative surveys. Those surveys need to include either basic market research questions or basic political polling questions, which might be added to get your opinion on a brand or an issue or a candidate.

Our data has been harvested, collected, modeled, and monetized - sometimes sold on as raw data, and sometimes licensed just for advertisers to be able to target us.

Imagine if Facebook's users received a universal basic income every day. This isn't going to be easy because it means that inherently their business model is going to take a little bit of a pay cut.

Corporations like Google, Facebook, Amazon, all of these large companies, are making tens or hundreds of billions of dollars off of monetising people's data.

The bigger a data set that you have, the more polls, the more surveys that you have that people undertake, the more accurate your models are going to be. That's just a fact of data science.

Ukip had undertaken a survey on why people wanted to leave the E.U. or not, and they also had membership data. So we were able to build personas out of that. That was work that would normally be paid for.

What if in a permission-based structure, you could decide if you wanted to provide value to advertisers or to political groups? Or, for instance, share your medical data for cancer research? All those options should be available for an individual to make.

I felt like I'd spent many years making excuses for my executives and making excuses for political candidates I was representing and their views, when some of those political views, in my mind, were very distasteful.

I think of myself as intelligent and strong and principled.

The use of data for political purposes wasn't invented by Cambridge Analytica. It started when I was on the Obama campaign in 2007-2008. We invented social media strategy.
