Why They’re Winning: Delphi

We’ll be diving in further next week, but here’s a quick overview of Delphi. Reply to this email with any questions you have for Dara and the Delphi team.

The Problem Space: Building AI that truly captures a person's essence - not just their knowledge, but their personality, speech patterns, and decision-making approach - has been the holy grail of personalized AI. Previous attempts have felt robotic, inauthentic, or simply uncanny.

Delphi's Solution: Founded in late 2022, Delphi AI has created a platform that generates AI "digital minds" (they're moving away from "clone" terminology) that don't just look like you, but think and communicate like you across text, voice, and real-time video. Unlike typical chatbots, these digital replicas engage in natural, flowing conversations while continuously learning and adapting from interactions.

Curious? You can chat with Dara’s clone here:

Insider Intel: In my conversation with Dara Ladjevardian, Delphi's founder, I was struck by how they're positioning themselves as a 500+ year institution. This isn't typical startup hyperbole – they're literally architecting systems to preserve human minds throughout history. It's less about chatbots and more about creating a "library of digital minds" that could eventually include historical figures and thought leaders.

Customers: Arnold Schwarzenegger, Codie Sanchez, Lewis Howes, Thiago Forte, Lenny Rachitsky, and Dr. Mark Hyman. See more here: https://www.delphi.ai/explore

Investors Include: Sequoia, Founders Fund, Lux Capital MVP Ventures

Technical Innovation: The company is currently focused on developing new "mind architecture" that better captures not just what people know, but how they think. They're designing interfaces specifically for mind creation and guided conversation flows. Their biggest technical challenge remains creating truly accurate representations of human thought patterns – a problem they believe they're closer to solving than anyone else.

Market Strategy: Rather than building a closed ecosystem, Delphi aims for portability across channels (SMS, WhatsApp, Slack, Discord, websites), giving users control of their digital identity while maintaining the platform. They see this as a winner-take-all category where they currently hold the first-mover advantage.

Why This Matters: In a world where personal attention is increasingly valuable yet limited, Delphi is pioneering a new category that combines the scalability of broadcast media with the personalization of conversation. This isn't just efficiency - it's a fundamental shift in how we think about preserving and scaling human expertise and connection.

They’re actively hiring and looking for ambitious engineers to join them in building the future of personalized AI replicas.

Candidate Testimonial:

Abby is a Rockstar!

She convinced me to take an interview when I wasn't even on the market and it turned into an amazing opportunity (exactly as she said it would). She has a knack for pairing talent to opportunities that are net wins for both parties. Aside from myself every member at beehiiv that she helped place has been a unicorn and a huge asset to our growth. She clearly has an eye for talent.
