What is LEx? facebook | twitter | community

The Lupulin Exchange (LEx) is a community of commercial brewers who regularly need to rebalance hop positions, understand market conditions, as well as leverage data, technology, and collective buying power to source future hop requirements. The LEx platform allows brewers, merchants, and growers to list hops for sale, search for varieties to buy, set up Hop Alerts, and make secure transactions.

Since 2014, the LEx platform has substantially improved transparency, market allocations (a major contributing factor to the hop crisis of 2008-9), and community member decision making, while providing a means for convenient, secure transactions.

You can learn more about our team and The Lupulin Exchange at our community where we post regularly.

Shane Kunkle facebook

Shane Kunkle has had a lot more practice writing software than brewing beer. That’s why John gave him a call when the idea for The Lupulin Exchange started brewing. Over the past 19 years, Shane has built a number of successful software companies and is currently the Chief Operating Officer at DevResults.

Shane graduated with honors in Computer Engineering from Virginia Tech and is a Microsoft Certified Professional. His first professional lines of code were written for radar systems and high-speed buses at general motor’s forewarn group.

When he’s not writing code, you can find Shane with his wife and three sons (!) – drinking rye whiskey, coaching youth sports or working out (generally in that order).
