As Harvard Business School seeks to expand its reach, it’s leaning on AI avatars to provide individual feedback. These avatars were created by a startup called HeyGen and are included in the eight-week, $699 HBS Foundry bootcamp for entrepreneurs.

The program offers live sessions with instructors every week, but the AI avatars are the ones providing feedback during practice pitches and board meetings. New York Times reporter Sarah Kessler tried this out herself by pitching an AI-generated copy of Flybridge Capital co-founder Jeff Bussgang. Apparently, both the real Bussgang and his simulacra were unimpressed by her plan to build ‘Uber for bananas,’ but Kessler said the virtual version offered a noticeably frozen smile during her pitch.

Project director Katharina Rings initially envisioned the AI component as something closer to a chatbot. However, after HBS released a trial version, students said they wanted a more guided experience. And while some college students haven’t been shy about expressing their negative feelings towards AI, Foundry participants told Kessler they like the avatars.

As for Bussgang, he acknowledged his digital copy is a little ‘creepy,’ but he said, “My students love it.”
