08 Yoni Medhin

Yoni Medhin, the CEO and Co-Founder of Grain4Grain, has a passion for finding out how to turn wonders out of what people normally consider waste.  And, with the help of his Co-Founder, Matt Mechtly, the two recently founded Grain4Grain a startup based in San Antonio, Texas that takes the spent grain, the primary waste product from the beer brewing process, dries it, and turns it into a low carb high protein flour.

The name, Grain4Grain comes from the fact that for every pound of flour they sell, they donate a pound to help feed San Antonio area families in need. To date, these two have been responsible for feeding over 650 families in the San Antonio area as well as diverting 4200 pounds of the spent barely grain from landfills.

In this episode of the Grow Ensemble Podcast, Yoni tells the origin story of Grain4Grain and his own personal appetite for social entrepreneurship, giving back and sustainability.

Listen in to our conversation for a few takeaways: 

  • How Yoni and his partner have utilized a local farmer’s market to refine their pitch and target market in the early days of the business. 
  • How Grain4Grain built partnerships with local breweries and repurposed the primary waste product from their beer brewing process to create a pancake mix that’s low carb, high protein and delicious!
