In order to improve the organisational performance of small and medium-sized businesses (SMEs) in Rivers State, this study focused on disruptive technologies as a strategic tool. The study was directed by two research topics and investigated two null hypotheses. The study used a correlational design. The sample was taken from a census survey of 223 employees of Small and Medium Businesses (SMEs). To address the study objectives and assess the hypotheses developed at the 0.05 level of significance, Pearson Product Moment Correlation (PPMC) was employed. Findings showed that disruptive technologies and the organisational performance of SMEs in Rivers State were correlated, and that there was a substantial association between the categories of disruptive technologies and the improvement of SMEs' organisational performance. Because of the correlation between the types of disruptive technologies discussed and the improvement of SMEs' organisational performance, as well as the relationship between disruptive technologies and organisational performance, it was determined that SMEs would benefit from regular deployment of disruptive technologies if they wanted to succeed in their businesses and maintain a larger market share in Rivers State. The report suggests that in order for SMEs to be relevant in the business world, they need be cautious of disruptive technologies and ready to adapt to changes and challenges since the global market is changing due to these disruptions. Furthermore, SMEs should keep using disruptive technologies to achieve success because they improve organisational performance. However, they need increase their capacity by developing and keeping employees who can effectively use the technologies.
