Uptake Holdings is a family of island ventures closing the loop from green waste to living soil, resilient sites, and stronger communities.
The ventures
Each company has its own market, but they share one operating base: local materials, durable relationships, and useful work.
Uptake Trading Co
Loyal Soil amendments, Kila Kiawe grilling wood, garden beds, farm pods, and edible-landscape design made on Oʻahu from Oʻahu's green waste.
BioSocks Hawaii
Bio-engineered erosion and sediment control for job sites, streambanks, shorelines, and drainage problems that need better BMPs.
Hawaiian Hydroseeding
Hydroseeding, hydrosprigging, bonded fiber matrix, soil stabilization, and dust control — the fastest, most cost-effective way to establish lawns and hold slopes.
KOKO
The easiest way to train hard anywhere — one map of every gym, open mat, and coach across Hawaiʻi. Starting with jiu-jitsu, built for every martial art.
From the field
Real work, shot on our own sites and gardens across Oʻahu.
How we operate
Uptake Holdings backs operating companies that solve visible, local problems before scaling the lesson outward.
The portfolio favors real products, field-proven services, and partnerships that make land, sites, and communities stronger.
