Our automated cell isolation system, the first in the world to process Hanwoo (Korean native cattle) tissue by the kilogram, yields muscle, fat and skin cells. It is 100 times more efficient than manual work (10~20g), makes 500~1,000 vials of master cells in one run, and grades them with AI tiering for storage in a 6,000-vial cell bank.


A food-grade, serum-free culture medium made with spirulina and chlorella extracts. Cells proliferate and differentiate in both 2D and 3D without fetal bovine serum, at 99% lower culture cost. Spent medium still holds growth factors and becomes a cosmetic ingredient.


An edible cell scaffold made from alginate extracted from wakame seaweed without chemical refining. 60% alginate, 90.7% dietary fiber, 0.00% heavy metals. Cells attach and differentiate as well as on animal collagen (Food Hydrocolloids, 2024). Our Gwangmyeong facility makes 320kg per run.


Our own bioreactor grows adherent cells in rocking single-use culture bags. Unlike stainless steel stirred tanks, it needs no sterilization plant, so it installs quickly and unit cost falls as scale grows. Equivalence is confirmed at 5L, 50L and 500L, and the Uiseong 1,500L line harvests within 10 days.
This video shows how the four technologies connect in the real process: cell isolation, cell bank, culture medium, proliferation, harvest and scale-up.
In pharmaceutical stirred tanks, sterilization costs grow with scale, which kept the cost of cultivated meat high. SeaWith makes single-use culture bags from food-grade materials that need no sterilization, removing that fixed cost.


Same cells, same medium, only the scale changes. Bag sizes reflect actual volume ratios.






Three lines: food, bio and cosmetics. Of the 7 that have completed research, 4 are already on sale, and cultivated Hanwoo beef is in the regulatory approval stage.
