Bio

I've always been fascinated by learning through practice, and this drive shaped my career path. I started in advertising, where I honed my skills in a dynamic, fast-paced environment. Over time, my passion for growth and hands-on experience led me to found Hivebreed, a marketing agency focused on helping brands grow in the digital economy. I also co-founded and exited Nekativ before joining Delivery Hero Cyprus as Head of Marketing.

I work exclusively with high-growth European startups, offering strategic expertise and hands-on execution across marketing, business development, and brand positioning.
