Like many good ideas, SUPERCOOL started with a meal.
In 2019, our co-founder Lin was working with a small mushroom farm in Anhui. One morning, the farmer handed him a fistful of freshly cut shiitake and said, "Cook these now — don't wait." What happened next changed everything.
Lin stir-fried the shiitake within two minutes of harvest. The umami hit was unlike anything he'd tasted from a supermarket — deep, almost meaty, with the clean sweetness of pine forests. By the time the food hit the plate, he was already asking the question that would become the company:
Why does everyone eat week-old mushrooms?
The answer was supply chain. By the time mushrooms travel from farm to grocery store, they lose 45% of inventory to spoilage, and 60% of the value disappears into the hands of middlemen. The mushroom that ends up on your plate is, optimistically, four days old and already half its flavor.
So we built SUPERCOOL to cut the chain entirely.
We partnered with Seven-Rivers Biotech in Shandong — one of the few mushroom-log producers in the world with EU, USDA, and China organic certification. We engineered a desktop chamber that maintains the precise climate each variety needs to fruit. We calibrated light spectrum, humidity range, and CO₂ levels against five years of growth data.
The result is the SUPERCOOL SmartFungi Box: a 13-watt, library-quiet, food-safe ABS chamber that grows up to 800 grams of gourmet mushrooms per log — at home, with one button, in seven days.
Today, thousands of families across China grow their own shiitake, oyster, lion's mane, and other varieties with SUPERCOOL.
Press one button. Wait seven days. Taste the difference 180 seconds makes.
Three principles that guide every decision.
Freshness is flavor.
Most food science is downstream of freshness. Build a product that lets people eat at peak, and the science takes care of itself.
Less is more.
No app. No subscription required. No learning curve. The best interface is the one you don't notice.
Honest materials.
Food-grade ABS. Real organic substrate. Real engineering. We don't cut corners where it matters.
