More about our agencies

Plug and Play

No need to look for different agencies or build temporary internal teams.
Connect your business to Sono and take off immediately.

One managment

We’ve built the element of circles into our domain and visual identity. Why? We were inspired by the Japanese management system called keiretsu (circle).

Our “keiretsu” consists of a group of four individual agencies. Each one is an expert in one area of marketing. When these specialists meet, they deliver added value to our solutions.

Business Skills and Craftsmenship First

Being a rockstar is not everything. Our teams understand how the industry works. Our communication brings results because it’s carefully planned. We believe in 100% craftsmenship.

We think it’s best to generate higher profits, not shiny awards in advertising competitions.

Together we've worked with more than a hundred Slovak and international companies.

Long Term

We often start with small projects, but our cooperation repeatedly turns into a long term partnership with clients.

They outsource a part or complete communication strategy to Sono (for example B2B business segment).

Smart Budget Allocation
at All Times

We get the bigger picture. If we see that a company needs to work on their visual identity or support their sale reps first, we won’t be pushing a pricy YouTube campaign.

Effective allocation of your budget is our priority.
