This research characterized and evaluated the marketing function of companies created from university entrepreneurship processes. It also correlated the marketing process with business results. In this qualitative study, a descriptive research was proposed. It collected information from primary sources (companies) through a survey. The survey was applied to 148 organizations belonging to four main economic sectors: service, industrial, agricultural and commercial. We evaluated four main categories of marketing (structure and strategy, products and services, customer relations and marketing mix). For each category, we defined variables that allowed the qualitative assessment of these companies’ marketing activities. It was found that their management style influenced their poor business performance in terms of sales and income, poor market adaptation and innovation processes. It was also found that they implemented failed marketing strategies. The influence of these factors affected the high mortality rate of these organizations.
