About
My name is Tea Mastelic. Originally Southern European, with a UK address for the last decade, I have always been driven by a passion for bringing positive change wherever I go.
The best compliment I’ve ever received? That I should create a job title called 'Problem Solver'! I thrive on understanding challenges, exploring their impact on the business, its stakeholders and employees, and turning those challenges into new opportunities for growth and innovation.
As a genuine relationship builder with years in tech sector where I have recruited across the UK, NA and EMEA for martech, fintech, ML start-ups, and someone who has my clients and candidates best interest at heart - I have decided to transform the recruitment industry as we know it!
Join me on this exciting journey of redefining recruitment!

Our Story
What is behind our name?
In Croatian, 'Opa!' is an expression of excitement and joy! It’s used to celebrate success, to embrace the unexpected and to inject a little fun into the moment. 💫
It is a word you shout when something surprises and delights you, when something awesome happens, when you’re full of enthusiasm and energy! 🚀 It conveys a sense of liveliness and positivity, which reflects the values or approach in our work —dynamic, engaging and focused on success. 'Opa!' represents a sense of community, celebration and connection. These values are at the core of our consultancy, as we work closely with our clients to create lasting, impactful partnerships.
'Opa' is the perfect word to describe the feeling we want to evoke during our talent processes: the thrill of finding the right fit, the joy of building meaningful connections and the satisfaction of seeing your team thrive.
