FAQ

Before we work together

How do we start working together?

It usually starts with a short call or a message through the contact form. We discuss where your marketing stands, what you want to achieve, and whether I am the right fit. If we move forward, the first step is typically an audit or a strategy session, so every recommendation is grounded in your actual data.

Do you work with businesses outside Greece?

Yes. George Tsiros works with brands in Greece and internationally, in English and Greek. Campaigns, reporting and communication run fully remotely.

What size of business do you work with?

From small and medium businesses that need senior guidance in a flexible setup, to market leaders that need an experienced specialist for a specific channel or project.

How do you collaborate with in-house teams or agencies?

In whatever setup works best for the business. Some clients work with George Tsiros as their complete performance marketing function; others bring him in alongside their in-house team or agency for audits, strategy or a specific channel. The goal is always the same: better results, with everyone working together.
