Agency pitch management including production

For many years we have been supporting our clients in disciplined and fair in media or advertising agency selection processes.  Our pitch processes end up not only with a partner selection, but also with a value-based guarantee of delivery. We also run pitches and negotiations in TV ad production.

Marketing effectiveness technology

We are the only one in Poland to offer not only the service itself, but the state-of-the art tools for self-management of marketing effectiveness analytics and sales forecasting. If needed we can run analytics for clients as well.


We are the partner of the leading global consultancies: Ebiquity and ID Comms. And the market leader in the Central Europe!

For few years now, we have been a close partner for the largest marketing performance and auditing company in the world, Ebiquity.

As of 2019 we have also partnered with ID Comms, a leading global management consultancy, specialising in media and advertising.

Just in Poland we service the largest number of clients out of all auditors present in the market (own research dated March 2019, based on Top100 advertisers as per Nielsen Audience Measurements data), that allows us to see the market from the broadest perspective and to have the largest and thus the most robust Pools and databases.

Our market share on the audited market is a solid 58%, with the closest competitor having less than half of it.
