KAH

How it works

From backyard surplus to neighborhood trade.

Kah turns the produce you can't finish into something your neighbors value — by barter or by sale. Here's how the platform works, start to harvest.

Getting started

Up and trading in three steps

No storefront, no farmers-market fees, no early mornings hauling crates.

  1. Claim your grower profile

    Sign up free and tell neighbors what you grow — a backyard tomato patch, a beehive, a few laying hens. No plot required to start.

  2. List your surplus

    Snap a photo, set quantities, and choose barter, cash, or both. Listings go live to verified neighbors near you.

  3. Trade with neighbors

    Arrange a porch pickup, swap harvest for harvest, and rack up reviews. Every good trade moves you up the grower tiers.

Grower tiers

Barter & cash

Two ways to trade what you grow

Start by bartering for free. Turn on cash sales whenever you're ready.

🤝 Barter — always free

Swap your surplus for someone else's: a dozen heritage eggs for a jar of raw honey, basil cuttings for heirloom seeds. No fees, ever, from your very first day as a Seedling.

  • Available at every tier
  • Zero platform fees
  • Great for building reviews fast

💵 Cash sales — 3% fee

Reach the Grower tier and you can sell for cash. You set the price; neighbors pay in-app. Kah's 3% fee is a fraction of a farmers-market stall or grocery markup.

  • Unlocks at the Grower tier
  • Just 3% per sale — you keep 97%
  • Specialty resale for top tiers
