Quentin Declerck

I help founders turn complex ideas into brands people actually remember.

After 15 years at the intersection of strategy and execution — co-founding and scaling Eclo (sustainable food), leading brand and marketing at Hoona (preventive wellness) from day one, and advising organizations across industries — I work as a fractional marketing director and brand strategist for companies building something that matters.

I'm not an agency. I'm a former founder who has sat across from investors, built visual identities from scratch, written positioning documents, and managed the full marketing stack — brand narrative to SEO/SEA, social media to B2B partnerships, photography to product storytelling.

I know what it costs to get this wrong, and I know how to get it right fast.

I integrate AI workflows into every engagement — not as a gimmick, but to spend more time on strategic thinking and less on repetitive execution. Faster turnaround, clearer outputs, sharper briefs. I also shoot photography in-house when needed, which means one less vendor and a more coherent visual story.

I work best with founders, brand managers, and leadership teams who need senior marketing thinking without the overhead of a full-time hire.
