Why Delphi?

We are redefining how knowledge is shared. We are enabling anyone to transform their unique expertise into an interactive experience, a digital version of their mind : a dynamic reflection of their knowledge and perspective. This is a completely new medium of knowledge transfer designed to make human intelligence deeply engaging and infinitely scalable.

Imagine a world where the collective wisdom of individuals isn’t locked away, but is instead a dynamic, ever-evolving resource anyone can engage with. We are building a future where human wisdom is abundant, learning is radically personalized, and individual brilliance scales effortlessly.

2,800 years ago individuals from across the Greek world and beyond, including kings, city-state leaders, and ordinary citizens, made pilgrimages to Delphi , seeking guidance on matters ranging from war and politics to personal affairs.

And now people will come to Delphi again.

What It Takes to Succeed at Delphi

You are ambitious – Our team is full of former founders, and entrepreneurial individuals who are taking on immense initiatives. In a world of barrels and ammunition, we are in search of barrels.

You are obsessed – Being great doesn’t happen by accident . It is hard. You know that and it excites you. We value people who want to be great.

You have a unique perspective, and tend to view the world positively – At the end of the day our product is a result of the collaboration of our team. We want people who are additive to culture. We value people who ask the question “What could go right?”

Why You Might NOT Like Working at Delphi

High Expectations : We demand excellence. If you’re not comfortable with high standards, constant iteration, and direct feedback, this environment may not align with your working style.

In-Person Collaboration : We believe in-person collaboration drives better ideas. If you thrive in a remote-first environment, this may not be the best fit.

Ambiguity & Uncertainty : Many of our challenges don’t have obvious solutions. If you’re not comfortable navigating ambiguity or tackling problems without previous solutions this might not align with your working style.

Not a 9-to-5 : We move fast, iterate often, and tackle ambitious challenges. This isn’t a clock-in / clock-out environment.
