This is more
than a product

collection.

It's the beginning of a new material system.

Fermentation-grown cellulose — replacing forestry with biology.

Three material
streams.

Grown Leather

A flexible cellulose-based material grown through fermentation in approximately 7 days. No animals. No petrochemicals. The material behind our first collection — dense, tactile, and home compostable in 90 days.

Grown Paper

Cellulose grown into paper-like sheets with unique texture and natural character. Designed for packaging, stationery, and creative applications where sustainability and storytelling matter as much as performance.

Grown Wood

A next-generation cellulose composite designed to mimic the strength and machinability of timber — without harvesting forests. CNC-ready. Applications in furniture, interiors, and manufacturing.

We're looking for partners

Manufacturers, designers, researchers, packaging companies, furniture makers — if you're building with materials, we'd like to talk.

"Let's build the next generation of materials together."

Whether you're a manufacturer looking for material alternatives or a researcher exploring cellulose composites — we want to hear from you.
