Founder

Dinos Chamalis

Dinos brings a rare combination to brand and digital transformation work: nearly a decade inside Accenture Technology Consulting, followed by 14 years building and running his own consultancy.

Greek-Peruvian by background and raised in Greece, Dinos earned his MSc in Distributed Systems and Networks from the University of Kent before spending almost ten years at Accenture, delivering technology and transformation projects for organizations including Philip Morris, HSBC, Barclays, SAP, Santander, Lloyds Banking Group, BT, and CLP Power Hong Kong. That work took him from Hong Kong and Switzerland to Milan and Munich, and taught him how large, complex organizations actually make decisions.

That enterprise consulting foundation is what sets Core Concepts apart. In 2012, Dinos left Accenture and founded Sociolus in London, then took it into the US market: Chicago from 2016, Miami from 2019. It became Core Concepts in 2020. What began as a digital marketing venture, backed by an early round of Angel investment from a London-based media venture, has grown into a studio trusted with more than 3,000 projects across 14 years. The portfolio spans high-visibility work like the Chicago Thanksgiving Parade, the Chicago Bulls’ team physician, and multiple TEDx events, and an Awwwards nomination in 2021.

Since 2021 the studio has been in Thessaloniki, where Dinos leads Core Concepts’ mission: applying the rigor and strategic discipline of enterprise consulting to help ambitious brands transform: not just their websites, but how they show up, compete, and grow.

Why Core Concepts

Yes, AI can build you a website in minutes.

Polish is now free, so a good-looking site no longer sets a business apart. What wins a customer is what a website builder cannot produce: motion that explains your product, tools your buyers can use, illustration drawn for your story, your real team on camera, and pages that buyers, search engines and AI assistants can read and quote correctly.

That takes people and experience. Core Concepts is 11 people (designers, AI specialists and system architects) plus two advisors, with 14 years of international delivery, 10 years inside Fortune 100 consulting, 3,000+ projects since 2012 and 81 Google reviews, rated 5.0.
