Bloomineral is building a carbon-negative materials platform based on a biomineralization process.
We take CO₂, industrial waste, and seawater and transform it into solid mineral forms that can be used in industrial materials, replacing emissions-intensive inputs with carbon-storing alternatives.
We’re an early-stage team working based primarily at LSCE in Paris-Saclay. Our current focus is simple: make the science work in real systems, and make it scale.
Shape how Bloomineral presents itself to partners, clients, and investors.
You’ll work directly with the founder and commercial team to clarify our messaging, structure our commercial materials, and make the company understandable to partners and customers. This is a hands-on role focused on B2B communication: decks, layouts, visuals, and brand coherence.
