“Cost of the U.S. embassy that hosted our reception: $1 Billion. Price of the round trip ticket from Pittsburgh to London: $550 (on Wow Air). Value of our relationship with Stylianos: Priceless! Thanks for everything Stelios!”

– Brian Kennedy | SVP for Operations and Government Affairs – Pittsburgh Technology Council

“Stylianos worked on our first ML proof of concept in late 2016. He was great to work with as he was able to operate on both a business level and a technical level. His original code has since formed the basis of our production NLP application, so many thanks for that work you did for DealGlobe all that time ago!”

— Alan Buxton, CTO, Founder, Early stage investor

“Stylianos is a very skilled data scientist and a great guy to work with. I really enjoy his enthusiasm, but most of all, I like his ability to communicate effectively. He knows how to make a client feel safe, understand their concerns and win them over with his methodical approach and professionalism. I am very happy with his services and I wouldn’t hesitate to recommend him.”

— Larry Kotch, Co Founder, brainbroker

“Dr Stylianos (aka Stelios in the office), is one of the most intelligent, passionate, and enthusiastic colleagues I have ever worked with. He has been instrumental in building the algorithms and methodologies that make up the Brandtix Score Index, and continues to find ways to refine and improve.

Stelios also has an infectious personality and his colleagues and external clients enjoy working and partnering with him. He’s a rare breed of a fantastic data scientist crossed with a great sense of humour and teamwork bias. A pleasure to have in the office.”

— Jon Rosenblatt, EMEA Marketing, Amazon game studios
