Delphi
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.

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.
