This article investigates the usage of an AI bot app called RNMKRS PitchPerfector to teach the sales skills necessary to deliver a successful elevator pitch. In particular, we wanted to know if the use of this app could increase student self-efficacy toward this critical selling skill. To analyze if RNMKRS had a real impact on students' elevator pitch self-efficacy, surveys were administered before and after the implementation of the RNMKRS assignment. In addition, class modality (online asynchronous and in-person) was tested to identify potential differences in self-efficacy growth. We found that the usage of RNMKRS did increase student self-efficacy in the delivery of an elevator pitch. That impact was not influenced by classroom modality suggesting that it would be equally effective for an in-person class as it would be in an online asynchronous course. Finally, we discuss the challenges that we faced implementing RNMKRS with students.
