Management Team

Billy Tiller

Billy is the fourth generation to manage a large family-owned production Ag operation, which he has overseen for the last 36 years, in an area west of Lubbock, Texas. This operation is his passion and his greatest business love. He has managed this endeavor while being involved in many other businesses throughout his career.

Billy’s past leadership includes almost 22 years on the Board of Directors of two separate telecommunications firms providing all levels of telecommunications to rural America from the pioneering days of cellular to the deployment of internet to its customers. He invested 9 years in a local agricultural bank as its Executive Vice President and served on its Board of Directors for 11 years. He was involved in daily lending to dozens of agricultural operations on the Plains of Texas and in the formulation and execution of the agricultural lending strategy of the bank. In addition, he managed the bank’s investment portfolio.

Billy has for the last 18 years operated as a founder, consultant and adviser to companies desiring to increase their understanding, market share or interaction within the agricultural community and he has built strong relationships with Texas Tech University and many agriculture industry innovators. Several of these companies have made significant progress surrounding renewable energy and agricultural innovation due to his involvement. He has made it a mission to create partnerships and alliances within industries that are sound and accomplish specific goals. Most of this work is rooted in rural America and are in the agriculture space.

Billy was a founder of Grower Information Services Cooperative (GiSC), and currently its CEO. GiSC was founded in late 2012 as the first cooperative to represent growers’ interests on the topic of data and information. The formal launch was in 2014 and 2015. GiSC is a national cooperative which currently has members across 41 states and all major commodities. He has several accomplishments in the “Big Ag Data” space which include being a speaker and panelist over the last few years at many events featuring ag data. Billy has also testified before the U.S. House of Representatives Committee on Agriculture in October 2015 at a public hearing titled: “Big Data and Agriculture: Innovation and Implications” and then again before the House Subcommittee on General Farm Commodities and Risk Management at a hearing titled, “The Future of Farming: Technological Innovations, Opportunities, and Challenges for Producers.” In July 2017, he was named by PrecisionAg Professional and Meister Publishing, as one of the Top 10 Most Influential Precision Farming Advocates for 2017. Throughout 2017 he worked to reset the focus of GiSC and 2018 should be the most productive year to date due to some very strategic alliances. He says his greatest accomplishment is building alliances and partnerships with companies and organizations that hold similar values in relation to growers’ data. He continually tells the GiSC Board, “Collaboration is the key to innovation, because great ideas are never invented alone!”

Billy holds a Bachelor of Business Administration degree in Accounting from Texas Tech University from 1986. He was the top graduate that year in the Rawls College of Business at TTU and addressed the graduates and guests at the ceremony. He is married to Christal Tiller for 36 years and they have four children and five (soon to be six) grandchildren.

Bryant Boyer
VP of Member Services

Bryant grew up in rural Central Indiana on his family’s corn and soybean operation. Agriculture was an important part of his upbringing and has guided him into his professional life. Bryant is a graduate of Oklahoma State University where he earned his Bachelor’s Degree in Animal Science with a Minor in Ag Economics. Post-graduation he went back and spent a few years on his family’s farming operation where he was actively involved in implementing and operating ag technology on the farm. From this, he realized the power of data within agriculture and the transformation that was taking place at the farm level. Watching the growth in the ag technology space and wanting to be a part of this industry revolution, Bryant took an opportunity with Conservis Corp. During his tenure with Conservis, he successfully built and developed several sales territories within different geographical growing regions of the United States. Bryant has been involved in several start-ups and appreciates the challenges and opportunities involved. He is currently pursuing his MBA at Texas Tech University’s Rawls College of Business, and looks to apply this degree in the ag technology industry. He is excited about the tools and opportunities that GISC can bring to growers and is always looking for ways to better GiSC’s grower-members.
