Circle CEO Jeremy Allaire trained an AI agent to mimic his voice and writing style, calling it the “Jeremy Allaire skill.” The bot, built on Claude, helped draft company communications and now lets over 1,000 employees chat with a virtual Allaire before reaching the real executive. The tool demonstrates a new way leaders scale personal influence.

Circle’s experiment mirrors a broader trend: executives, consultants, and academics deploy AI doubles to answer routine queries and deliver localized content. Delphi’s CEO Dara Ladjevardian, who raised a $16 million round led by Sequoia, says the avatars act as “new artifacts of your mind,” offering a scalable proxy for presence in multiple languages daily real-time everywhere.

Entrepreneurs like Lenny Rachitsky and advisors such as Alisa Cohn use AI bots—Lennybot and an AI avatar—to field hundreds of inquiries, reducing personal time while maintaining brand voice. Yet some users report a preference for human interaction; a Harvard professor’s AI assistant failed to replace face‑to‑face office hours, illustrating limits to substitution for all.

The rise of AI doubles signals a shift in how companies manage internal communication and client outreach, but the technology is not a wholesale replacement. Firms must weigh the cost of building and maintaining custom models against the value of human touch, especially when brand credibility hinges on personal connection for high-profile stakeholders or investors.
