THE FOUNDER
Christel Diaz is the Founder & Creative Director of Blumm. Born and raised in Spain, after years of working across global markets and traveling nearly 70 countries, she built Blumm with a rare combination of instincts: the global storyteller's ear, the strategist's eye, and a deep fluency in internet culture.
Today, she leads projects across brand building, content production, creative writing, social media marketing and web development for brands spanning hospitality, fashion, media, lifestyle, and impact-driven industries. Her work combines storytelling, humor, psychology, and trend awareness with a strong focus on building communities people genuinely want to engage with.
