Head of Future Food

Desh Ramnath is a serial entrepreneur and ecosystem architect, driven by innovation, collaboration, and systemic impact.
After founding and scaling his own ventures, Desh expanded his scope across industries and even into politics. These experiences shaped a clear conviction: meaningful innovation does not happen in silos, but through well-designed ecosystems that connect people, technology, capital, and value chains.
Curious about how younger generations and the emerging economy approached entrepreneurship, Desh entered the innovation space as a mentor at UtrechtInc. From there, he went on to design and support startup ecosystems across the globe. His journey came full circle when the Municipality of Westland invited him into the Controlled Environment Agriculture (CEA) domain—reconnecting him with both his professional interests and his roots as a Dutch citizen of Indian origin, born in ’s-Gravenzande.
What began as an exploration quickly evolved into a mission. Inspired by the transformative potential of horticulture, Desh became deeply engaged with entrepreneurs in the food and flower industries. Together with Mart Valstar (Best Fresh Group), he initiated strategic conversations with the Municipality of Westland, ultimately leading to the creation of HortiHeroes—an innovation acceleration platform for the global Food & Flower ecosystem.
Alongside close collaborators Bas Allart and Roel Raatgever, Desh co-founded HortiHeroes and built the team that successfully scaled the platform to its next phase. During this period, he was invited by fellow Entrepreneur-in-Residence Maren Schoormans to co-develop the international strategy of Dutch Greenhouse Delta, supporting its global ambitions in CEA technology. What was intended as a short engagement evolved into several years in which Desh fulfilled multiple strategic and leadership roles within the organization.
These experiences converged into a new venture, Horizon11—a strategic advisory company focused on accelerating impact through collaboration, innovation, and purposeful ecosystem design.
While remaining active across multiple ventures and industries, Desh firmly believes that AgriFood is a key enabler of healthy living on a healthy planet. It is one of the few industries where commercial success and positive global impact truly align. This belief, combined with his experience and ambition, led him to join the HortiScience Innovation Center.
Returning to the role of a starting entrepreneur, Desh looks forward to creating value once again—building the future of AgriFood innovation from the ground up.

I am a senior lecturer and researcher at the HAS green academy University of Applied Sciences ('s Hertogenbosch, NL), department of Agri and Business, Team Horticulture and Arable Farming. Within the research I do, I am associated with the Professorships "Green Health (Groene Gezondheid)" and "Horticulture Technologies". This entails doing research, using modern and innovative technological advances within horticulture, to ensure quality (internal, phytonutrients, product health) of produce, allowing consumers to have an informed choice about the quality of their produce and the health benefits this may provide them upon prolonged consumption. Within the UAS system, the main focus of our research is to closely together with companies, Universities and governement to ensure the research we do is relevant and applicable in the sector. 
My previous experiences include:
PhD (University of East Anglia; John Innes Centre, Norwich, UK) 2002 (cereal starch metabolism);
PostDoc on Pollen-pistil interactions (Radboud University Nijmegen, NL)
Agricultural consultancy ( Sustainable Crop Management; ADAS, Cambridge, UK)
Seed Production Researcher (Nunhems / BASF Vegetable Seeds, NL)
Cereal breeding (Sorghum; DSV, NL)

Greenhouse Consultant

My name is Bernard van Loon I currently work as business developer for Delphy Digital with a focus on North America. With past experience as a data scientist and an Msc in Plant Science focused on statistical crop modelling from Wageningen University, my aim is to combine theoretical and practical solutions to help growers take the next step in Data Driven Growing. Light is the key aspect for yield, and understanding how a crop reacts to light during different stages and scenarios is key for yield prediction and crop management. One part of Data Driven Growing with Delphy's QMS solutions is alloiwing a grower a deeper insight into how their lighting (indoor and outdoor) interacts with their crop throughout the growing season.
