With an experienced founder at the helm and a dynamic team of talented freelancers, we understand the unique challenges and opportunities that come with launching and growing a business.
Géraldine founded GCLS Consulting after 25 years spent shaping the voice of brands across industries , from global tech companies to innovative startups. Her journey has always been driven by a belief: that communication is not decoration. It’s transformation.
With a dual background in brand strategy and executive communication, Géraldine has built a reputation for cutting through noise with clarity, structure, and substance. She helps ambitious leaders turn complexity into simplicity, and messaging into momentum.
Before launching GCLS, she led marketing and communication teams at international firms, navigated IPOs, repositioned brands, and advised CEOs on high-stakes narratives. She also built two companies from scratch, including a luxury fragrance house giving her both the empathy of an entrepreneur and the precision of a strategist.
Fluent in French, English, and Spanish, Géraldine is as comfortable in a boardroom as in a creative sprint. She believes in smart branding, useful beauty, and messages that move both people and performance.
“To give bold brands and brilliant founders the tools to speak with impact — and build communications that actually change things.”
