CEO @RE-wize

About

A Digital Marketing & Growth Marketing enthusiast. I love when Marketing & Sales are combined with great design & when strategy reflects on the bigger picture of a company's vision.

Started my career early on in 2007 as a Sales agent & later on IT support at the National Bank of Greece, which gave me an understanding of sales & technical background, which helped me understand tools & sales later on.

Joined Buldoza.gr in 2014 as Digital Marketing Specialist & Account Manager for brands like Attrattivo & Laura Ashley Greece.

In 2017, I became Marketing Director at Laura Ashley Greece & co-founded two start-ups, whitefabric.gr & fotojar.com.

In 2019, I founded the agency re-wize.com which specializes in Performance Marketing & e-commerce growth as a Shopify Partner.

In 2020, I started an ongoing collaboration as a Marketing & Growth Manager at Vimachem, a leading AI Platform that helps pharmaceutical and biotech companies to scale faster with greater flexibility.

In 2022, I founded a B2B agency uplify.agency which helps B2B companies expand their online presence via growth marketing. As a HubSpot Solutions Provider, we provide a roadmap to companies to generate more leads & revenue.
