10 European startups building trustworthy adtech

Adtech is a market vertical full of innovation, constantly evolving, but one that also receives a degree of criticism and incites some controversy. From concerns over privacy to fears of exploitation, ad tech innovators need to toe a careful line between achieving what businesses want, and doing so in a way that is ethical for the end consumers. Here, we look at 10 European startups that are helping achieve just that. 

Adtech is a fundamental part of digital marketing strategy and as the world has gone increasingly digital, it’s now accepted as a fundamental process to business strategy. Businesses ultimately need to share their brand, sell their product, and become visible – in a digital world, ad tech helps achieve that whilst optimizing budget expenditure.  It’s about delivering the right content at the right time to the right consumers. 

Global advertising is massively growing and, according to Hubspot, it reflects a total spend of €634 million

However, as advertising goes digital and competition between businesses ramps up, the stakes are higher than ever before. And companies are trying to use every opportunity and new innovation at their disposal to reach their consumers – before their rival does. As a result, consumers are getting worried about their privacy.

​​Daniel Tjondronegoro, Co-Founder, Beatgrid:People need to know that their data is safe and if possible, that they are involved in something bigger and better. Now transparency comes first, and we have witnessed this first hand, seeing how European advertisers have hopped on the cross-platform audience measurement train, and have started to experience the benefits and the positive outcome of user-centric “adwaste”-cutting solutions. With such change being driven out of Europe, the global advertising scene is taking note and we now sit at the forefront of a period of huge transition, for the better.”

There’s no doubt, some ads are just creepy. Ever had a conversation with a friend about something or some product totally randomly and then seconds later seen it popping up on your Instagram feed? Or the ads that keep following you after you make an Amazon purchase. 

As the power of ad tech grows, more regulations have been coming into place to monitor the market and ensure that ad tech grows for innovation not for exploitation. These regulations have landed some ad tech companies in hot water and also pushed businesses to rethink their ad approach. Apple, for example, did away with unfettered access device-level identifiers – IDFA (“Identifier for Advertising ”), instead forcing all iOS app makers to get permission to collect and use IDFAs from users. And let’s not forget that in August this year, the creepy tracking ads world took a blow as French ad tech unicorn Criteo was found in breach of regulations and hit with a €60 million sanction. 

So, with this context in mind, we wanted to take a look at how innovation in ad tech can be used for good. How it can be harnessed in a way that connects brands and consumers when they need and wants it  – and so without exploiting or being creepy. After doing some digging, we found that Europe is pacing the way forward in this, and startups are leading the charge
