About

The Journey So Far

Oscar Mairey at a conference

I discovered stoicism early in my youth, and it shaped how I see everything. We all leave this world eventually — so the real game is making an impact that outlasts you.

Technology, to me, is a form of art that raises moral questions in its application. The best philosophers were also engineers — from Archimedes to Wittgenstein. They would have had a lot to say about AI consciousness.

I fell in love with crypto around 2020 — the combination of cryptography, game theory, and economic incentives opened my eyes to new ways of organizing human cooperation. That led me deeper into AI, and now into deep tech as a whole.

Chapters of Life

2020 - 2022

Down the Rabbit Hole

I discovered crypto for the money, but stayed for the people. Behind the speculation was a vibrant community that accepted everyone as they were.

2022 - 2024

Building & Shipping

Social intuition was my only asset. I used it to co-found Le Crypto Daily, now the largest francophone crypto media. I also launched a SocialFi app that raised $1.5M and debuted at CES Las Vegas.

2024 - 2025

Going Global

I joined an AI company building blockchain-backed datasets as a core team member, relocating to Dubai to take on the role.

2025 - Present

What’s Next

I joined ARTE One, an algorithmic asset manager powered by AI. In parallel, I took an operational role at Chainraizer — applying blockchain to traditional finance through private equity tokenization.
