About Yellow Seed

Yellow Seed is creating a tool to facilitate small-scale farmers accessing fair markets and buyers sourcing ethical and sustainable products.

These small-scale farmers are the 2.6 billion people around the world who farm diverse crops on small plots of land. Many of these farmers are currently excluded from global supply chains, as modern markets are geared towards high volume production and mechanized efficiency.

Supporting these farmers is key to preserving biodiversity, providing quality food sources, and improving the economic health for our global communities. Conscious trade is our future.
