Koch Industries

One of the largest privately held companies in the US, with dominant positions across energy, manufacturing, and enterprise software via Infor

Koch Industries is one of the largest privately held companies in the United States, headquartered in Wichita, Kansas. Founded by Fred Koch and now led by Charles Koch, the conglomerate spans manufacturing, energy, chemicals, agriculture, and technology. Its investment arm, Koch Equity Development, has made substantial bets in enterprise software and technology, most prominently the acquisition of Infor in 2020 for approximately $13 billion, making Koch the sole owner of one of the world's largest enterprise resource planning (ERP) software providers. While Koch Industries itself is not an AdTech company, its portfolio companies and technology investments touch the broader data, analytics, and enterprise software ecosystem. Infor, under Koch's ownership, serves industries including manufacturing, distribution, healthcare, and retail with cloud-based ERP, supply chain, and analytics solutions. Koch's data and analytics capabilities, combined with Infor's industry-specific software, create an enterprise technology stack that intersects with marketing technology, supply chain optimization, and business intelligence. Koch's relevance to the AdTech and MarTech ecosystem is indirect but meaningful — through Infor's CRM, marketing automation, and customer experience modules, as well as Koch's broader investments in data-driven businesses. The conglomerate's scale, with revenues estimated over $100 billion annually, gives it significant leverage to invest in and influence enterprise technology markets, including those adjacent to advertising and marketing technology.
