About Ei
Jumping in to help marketers since 2007
Ei Advisory started life in 2007, with three people sitting at laptops around a table with a single telephone in the middle. When the phone rang, they would compete to see who could answer it first.
Fast forward to today. We have two offices, in London and New York, and employ a team of exceptionally bright individuals from diverse backgrounds.
The way we work has changed enormously, but that appetite – to pick up the phone and jump in to help – is still at the heart of everything we do.
Evidence. Confidence. Results.
