Delphi

Delphi lets an expert, coach, or public figure build what the company calls a "Digital Mind" — an AI version of themselves that can answer questions in their own tone and voice, around the clock, without them personally responding to every message. It's trained on the person's own material: documents, past writing, videos, and social media posts, and it grounds its answers in citations back to those sources rather than generating unconstrained responses. The platform targets coaches, authors, investors, speakers, and other experts who want to scale one-to-one interaction without hiring a team, whether that's answering audience questions, running a paid Q&A subscription, or capturing leads. Voice responses are powered through a partnership with ElevenLabs, so a Digital Mind can sound like the real person rather than a generic text bot. Delphi is a Miami-based company founded in 2022 by Samuel Spelsberg and Dara Ladjevardian, and has raised $19 million total, including a $16 million Series A led by Sequoia Capital in 2025. More than 2,000 experts and creators reportedly use the platform. Pricing isn't published on the homepage, so anyone evaluating Delphi needs to go through a signup or pricing-page flow to see actual costs.
