Portrait of Felix Knox

Felix Knox

Technical Director · Product Engineer · Company Builder

I build companies end to end: vision and strategy, product and brand, and the systems underneath. From global brands to Swiss crypto finance, Web3 protocols, and AI-native science.

Profile

AI made prototypes cheap. Platforms that carry real money, real users, and a company built around them are still rare. Building them takes experience, not just tooling.

I have built across every layer of a company. Co-founded studios and led technical direction on award-winning campaigns for global brands. Led digital at Bitcoin Suisse. Architected Polimec’s application layer from the ground up. My role spans vision, product, design, and code, keeping what the company sets out to do connected to what the team ships.
