What got us from 0 to 1 isn't what will get us from 1 to N.
3 years ago, before the launch of ChatGPT, we set out to start a company that most people thought was impossible.
To be honest, many people still think it's impossible today.
Multiple rounds of rejection and external doubt later, we went from 0 to 1 and created the category of "Digital Minds". We built an exceptional team and earned the backing of investors like Sequoia and Founders Fund.
It wasn’t easy. There were probably moments we should have pivoted.
But we kept pushing.
Today we work with some of the top minds in their fields - @lennysan, @bhalligan, Eckhart Tolle, Vanessa Van Edwards, Dr. Mark Hyman.
Delphi is the place people go to learn from them, get their advice, and access their expertise.
Looking ahead, we believe Delphi is how every human will represent themselves in the AI age. A new way for people to meet, connect with, and learn from one another.
But to get there, we need to evolve.
Delphi is looking for a VP of Engineering - someone who has taken a consumer platform from 1 to N and knows the tradeoffs required to build infrastructure that supports millions. An AI-native builder and culture carrier.
In the early years, I had an almost allergic reaction to "experience" - I believed purely in slope over y-intercept. As we've scaled, I've come to understand that to get where we want to go, we need someone who has already been there.
If that's you, or someone you know, I want to talk.

Xfund faculty advisor Paul Gompers has a new paper out that upends widely-held beliefs: “That literature portrays failure as a stigma,” says Gompers. “It might make you think that if you start something and fail, people aren't going to want to hire you.” hbswk.hbs.edu/item/why-a-fai…
