Otter AI transcription leaks confidential investor call

An automated Otter.ai transcription bot inadvertently recorded and distributed sensitive, "off-the-record" venture capital discussions to a researcher after he had already left the meeting, resulting in a major breach of confidentiality and the collapse of a potential business deal. What happened Alex Bilzerian, an independent engineer and researcher, had a Zoom meeting with a venture capital firm that used Otter AI, a popular transcription tool, to record the conversation. After the meeting, Otter AI sent Bilzerian a transcript that included hours of private conversations that occurred after he had logged off. The investors had continued discussing confidential business matters, unaware that Otter AI was still transcribing. Bilzerian shared details of the incident on social media, expressing his discomfort with the firm's failure to protect sensitive information. Why it happened The investors failed to end the Zoom call or turn off the AI transcription after the meeting, which caused Otter AI to continue recording and transcribing the conversation. This is likely due to a lack of awareness of the technology's capabilities and limitations. What it means For businesses , the incident highlights the risk of trade secret misappropriation and the loss of legal privilege.
