👫 About the team

At Equativ, we’re on a mission to develop advertising technologies that empower our customers to reach their digital business goals.

Our innovation team based in Paris, Nantes, Limoges, Krakow and Berlin is composed of 90 straightforward and energetic engineers working in an Agile environment and ready to tackle the most complex technical challenges.
