To Mark Cuban, coffee could be worth millions — if it's served with a compelling backstory.
Take Kahawa 1893, a San Francisco-based coffee company that Cuban called a "brilliant idea" on a recent episode of ABC's "Shark Tank."
In total, Kahawa 1893 and its patrons have given at least $20,000 to women farmers since launching in 2017, Nyamumbo said.
The following year, she launched Kahawa 1893 — named after the Swahili word for coffee, and the year coffee was commercialized in Kenya.
After O'Leary backed out of negotiations, guest Shark Emma Grede — who admitted she didn't even drink coffee — jumped in, offering $350,000 for 12.5% of Kahawa 1893.
