Thomas Guilbert is a seasoned strategist and online marketer. He has dedicated his career to using his marketing and science engineering background to promote products that address health issues.
Thomas possesses a Master of Business Administration (MBA) from HEC Paris, the top business school in Europe, and a Master’s degree in Engineering from AgroParisTech, establishing a solid and distinctive foundation for brands to thrive in the health and science sectors. He has successfully crafted and executed groundbreaking strategies to transform various sectors, including beauty, marine conservation, and health-focused clothing. By combining his knowledge in marketing and science, Thomas has revolutionized these areas, focusing on their health advantages and societal importance.
Starting his journey in France at L’Oréal, where he specialized in marketing products, Thomas then moved to London to work at Nausicaa Aquarium. He later joined the L’Occitane Group, focusing on expanding and growing the fast-growing cosmetic brand Erborian. In this role, managing a budget exceeding $2 million, Thomas achieved a remarkable threefold return on investment (ROI) for Meta campaigns across the French, UK, and US markets, blending traditional and innovative marketing approaches.
Promoted to Digital Manager in just two years, Thomas took on the challenge of reviving a struggling organic brand, Melvita. By concentrating on attracting new customers and improving the shopping experience to showcase the brand’s uniqueness and scientific approach, he led to an impressive 36% increase in sales year over year and brought the brand back into the black. Furthermore, by exploring new markets and expanding the brand to online platforms like Amazon and other e-commerce sites (where this niche is still growing but not yet fully established), Thomas generated over €1 million in additional sales over the last two years.
A standout quality of Thomas is his ability to simplify and explain complex technical ideas in a way that connects with consumers. This skill has been especially valuable in his current position at HAVN, where he is developing EMF-blocking clothing for everyone. His scientific background has helped him understand the technical details of EMF protection, while his marketing background has allowed him to translate these details into engaging stories that highlight the product’s benefits and appeal to a broader audience. Through creative strategies for attracting new customers and targeted Meta and TikTok ad campaigns, he has introduced a scalable approach for HAVN, leading to a 125% increase in net sales. His efforts have also resulted in a 10% profit return on advertising investment (PROAS), underscoring the success of his online advertising strategies and boosting brand recognition.
Thomas is passionate about fusing science and marketing to develop innovative solutions across related industries. As a member of the Forbes Council, a juror of the international Digiday Awards and Shorty Impact Awards, and a leader in the Bluewhale Mastermind Group in the D2C industry, he plans to continue integrating with leading experts and connecting with consumers on a deeper level, making complex concepts comprehensible for the public.
