About
Hi, I’m Kosta Diamantopoulos, a performance-driven digital media professional focused on building adaptable, cross-channel skillsets that drive growth. I thrive on understanding the why behind campaigns, and I love turning data into actions that move traffic, convert leads, and scale business performance.
Over the years I’ve led full campaign activations for Telstra Belong at Omnicom, built measurement stacks, and steered multi-channel programs across Meta, Google, DV360, TikTok, and The Trade Desk. I enjoy crafting systems and automation (speed-to-lead and CRM flows) that convert clicks into customers, and I’m energized by helping both global brands and local business owners scale their impact.
