COSTAS MANTZIARIS

Costas helps people & companies make better decisions and uncover business opportunities. That’s why in 2018 Costas and his co-founder, Giorgos Vareloglou, started REBORRN.

Prior, Costas was the Chief Executive of Isobar & iProspect in Greece. He launched Isobar & iProspect in 2015 afterDentsu Aegis Network acquired his company, Mindworks. Along with his business partner Giorgos, they started Mindworks 12 years ago. From a tiny, specialised, performance marketing agency they transformed it into the fastest growing and largest independent digital communications agency in Greece.

During Costas’ tenure, Isobar & iProspect (formerly known as Mindworks) won more than 100 awards globally along with the recognition of clients, peers and employees. In 2017, Costas’ & Giorgos’ innovative projects were featured in the Advertising Age.

Although an introvert, Costas loves public speaking and teaching. He has been a speaker and trainer for more than a decade. From conferences to universities and seminars, he has trained more than 3.000 people in Greece and abroad.

Costas may have excelled in the “digital marketing” sector for the past 15 years, but solving real business challenges is what makes him 'get out of bed'. By merging data with intuition, he consults enterprise clients on how to build better experiences for their customers and achieve their goals.
