Identity as a Service
with German Precision and Global Reach

Cross-Device Technology

Consumers constantly switch between their digital devices, such as smartphones, tablets, desktops, etc. The process of tracking consumer behavior and building a single digital identity for each user has become more complex.

By accurately determining which devices belong to the same user, the Cross-Device Technology enables you to create data-driven strategies with focus on people-based marketing. This approach helps to increase engagement with your audience across all their devices and optimizes your marketing budget and analytics.

Proprietary Machine Learning algorithm

100% compliant with European and German privacy laws

Seamless integration

Reach people across all their devices!

Revolutionize the communication between your brand and your audience by determining exactly when and where to engage with your audience in order to drive them through your conversion funnel. Cross-Device technology creates a single digital identity for each consumer. This allows you to coherently communicate with your target audience, no matter what device the customer is using.

How? developed a set of proprietary Machine Learning algorithm to identify all devices belonging to the same user. is offering different solutions for a number of Cross-Device use cases.

Identity Graph

Uncover which devices your users own and how they use them to interact with your brand.

Understanding your audience and their online behavioral patterns enables you to define the perfect strategy to increase engagement.

Built in-house, Cross-Device Identity Graph uses probabilistic data to make predictions and deterministic data sets to train the algorithms.

ROPO360 Analytics

Research Online, Purchase Offline Analytics

Create a solid link between your digital advertising activities and offline conversions in your shops, restaurants, dealerships, outlets, service points – wherever you want your consumers to “convert” in the offline world.

Analyzing the customer journey of your consumers, including all her devices, enables you to measure each individual digital advertising placement, optimize digital media budgets and identify those customer journeys most frequently used by your customers.

How do we integrate with Technology? support two ways of integration: by tracking codes or server-to-server.
The former could be done with JavaScript codes which requires either cosmetic changes (campaign or use-case specific) or for NO changes at all.
We can also provide an IMG tracking code but in this case, it needs to be customized.
The second integration type (server-to-server or s2s) is just a RAW data file sharing using (s)FTP or AWS S3. For this scenario some additional criteria must be met, i.e. presence of all attributes in the data exports requires for the calculation.
Before the project starts, our Customer Team is always involved in the use-case clarification discussion to make sure the most beneficial way of integration is chosen.

How does the algorithm work?

It’s our secret sauce :)‚ However, to understand the process a bit better we strongly suggest reading our 
White papers. Definitely it’s worth spending 30 minutes to understand the idea of cross-device technology.

What is the USP?

The USP is privacy compliance and strongest local Cross-Device device pool in central Europe. works on 100% opt-in or consented users, and thus is adhering to the strict German data privacy laws. Active user consent means that will not process any data without a user actively agreeing to do it. The user’s consent for processing can be withdrawn anytime via several opt-out mechanisms.

What is the difference between deterministic and probabilistic approach? Can’t I do cross-device with my log-in data only?

Deterministic data (also called «label data») includes information such as user name, email address, etc. tied to a specific user. It is considered as one of the most accurate ways to identify a person in the online world. Typically, social media platforms, gaming sites, and large eCommerce businesses have the largest number of log-in data. However, when the person moves away from these platforms to other digital properties or does not login to a specific app or website – it is almost impossible to track the user across their multiple devices. Here, a probabilistic approach is needed in order to solve for online identity resolution.
Probabilistic data itself means observation data that does not contain a persistent identifier belonging to a given user (e.g. an e-mail address). A probabilistic identity solution collects a wide range of signals from the observation data and computes connections between the underlying device identifiers. The more matching attributes that are received and mapped for a given device and user, the higher the likelihood that these device identifiers belong to the same person.
In summary: A deterministic Cross-Device solution works well, as it holds high precision level between the device connections, however, it lacks in scale. Using probabilistic solution in addition to the deterministic solutions increases the scale of the approach at relatively high precision rates (+90%).
