Senior Software Developer

Company Description

We help brands make BOLD MOVES

Nowadays, brands want rapid, spectacular growth and they expect media to deliver it.

Clients used to give us media briefs that said “deliver 80% awareness” or “give me an impactful Christmas campaign.”

Now we hear

“Take me from 4th to 1st in my category”

“Help me grow 10% in a market declining 10%”

“Make me the most loved brand in my industry”

These are huge asks of media, that can’t be met through tweaking the media plan of two years ago.

Decades of advertising research prove that without a big change, large brands stay large and small brands stay small.

This is why Zenith help brands make BOLD MOVES.

Bold moves are big, brave changes to media strategy, delivering more impact for brands and more value for consumers.

Bold moves are backed up with a solid forecast – they are a better path to growth.

Bold moves build a partnership – we believe in this approach so much we link our growth to your success.

Bold Moves bring bigger ROI

This approach works for our clients, our people and consumers – it’s why we are recognised as the UK’s best media agency.
