A founder-led deep-tech initiative.
33CLEANFEED brings plant biology, industrial engineering and measurable product quality together. The ambition: controlled biological production as a repeatable system — with standard interfaces, crop-specific recipes, traceability and an honest measurement of cost and quality.
From a practical challenge to a system approach.
33CLEANFEED grew out of an entrepreneurial, systems-oriented look at a practical challenge: how do you make biological production not only possible, but better controllable, measurable and usable for the market?
Founder Bryan Damhuis combines commercial experience in B2B, e-commerce, trading and entrepreneurship with founder-led development work on the technical and biological architecture of 33CLEANFEED.
The focus is on connecting disciplines that are usually looked at separately: crop recipes, water and nutrients, air and climate, biosecurity, sensors and automation, quality control, batch data and the real cost of released product. Where hypotheses go beyond existing data, we want to test them with farmers, engineers, laboratories, agronomists and knowledge partners.
The ambition is big, but the route is evidence-led: design, pilot, measure, validate — and only then scale.
Production that is measured, controlled and traceable
A production environment in which biological output is not only grown, but systematically measured, steered, controlled and made traceable per batch.
What we develop ourselves.
M01–M09
The conceptual modular architecture integrating cultivation, water, air and climate, biosecurity, automation, QA, data and economics.
Design
Crop & composition
Hypotheses and validation questions on crop recipes, minerals and DCAD, alfalfa, plant compounds and seed-related input risks.
Internal R&D
From idea to test
Turning research questions into testable variables, comparisons with conventional and standard hydroponic systems, batch registration and KPIs.
Internal R&D
Partners & consortia
Took part in the Horizon Europe Cluster 6 brokerage event in Brussels (October 2026); exploring collaboration with companies and knowledge partners.
Open for partners
The people behind 33CLEANFEED.
Founder
Leads the vision, system architecture, product direction and research questions. Commercial background in B2B, e-commerce, trading and entrepreneurship since 2019.
Co-founder
Based in Twente, The Netherlands. For building, laboratory analysis, agronomy and independent validation we work with specialist partners.
Six principles behind every decision.
Technical sobriety
First specify and measure, then conclude.
Biological precision
Recipes and success criteria differ per crop and growth phase.
Transparency
Facts, assumptions, hypotheses and targets are never mixed.
Modularity
Scale through standardised modules and interfaces, not endless custom factories.
Quality discipline
No product release without a QA decision and a suitable specification.
Customer value
Technology only counts commercially when a demonstrable outcome helps the customer.
