Dooor is the strategic
partner for AI innovation
The power of artificial intelligence will redefine every industry. But this power demands a new foundation, one built not on hype, but on mathematical proof, data sovereignty, and unwavering trust. At Dooor, our single focus is to build this foundation.
Experience in CSN, Harsco, etc.
Foundation in Industry (The Steel Era)
Our roots began in heavy industry, applying technology to optimize over 80% of the Americas' steel park. This taught us the non-negotiable value of operational efficiency and minimizing cost per ton.
700+ startups supported
Transition to Decentralized Trust (The Blockchain Era)
We leveraged our knowledge to drive growth in the blockchain ecosystem, supporting over 700 startups. This focused our vision on verifiable proof, security, and decentralized data sovereignty.
2025 - Founding
The Verifiable AI Revolution (The Dooor OS Era)
We applied the same mindset of mathematical proof and large-scale efficiency to AI, building the Verifiable OS. Founded in 2025, Dooor is the infrastructure for the new agent economy.
Two Worlds,
One Vision
Our Mission
To empower organizations to transform their wisdom into value, while maintaining absolute sovereignty over their data and models.
Our Vision
A future where critical decisions are enhanced by AI that is transparent, provably, honest, and securely under the control of its owner.
What We
Stand For
Our culture and our code are guided
by a core set of principles.
Human-First
We build powerful tools designed to augment human potential, not replace it. Technology must always serve its users, making them more capable and effective.
Composed & Disciplined
We believe in quiet excellence. Our design philosophy favors minimalism, clarity, and robust performance to build things that work, reliably and elegantly.
Empowering by Default
We provide the tools and frameworks that give our partners control, ownership, and the freedom to innovate on their own terms, without restrictive lock-ins.
Transparent by Design
We believe trust is earned through proof. From our open communication with partners to the auditable nature of our platform, we are committed to building in the clear.
Thiago Castroneves
Co-Founder & Chief Executive Officer
Forged over 15 years designing mission-critical solutions for industrial giant Enviri, Thiago bridges the gap between the realities of heavy industry and the frontier of decentralized technology. His unique market view comes from evaluating over 700 tech projects as Head of Business Development for the Moonbeam Foundation.
Thiago Castroneves spent over a decade in global steel manufacturing at Enviri, where failure meant millions in losses. Security and reliability weren't buzzwords—they were survival requirements. Later, evaluating 700+ Web3 projects at Moonbeam Foundation, he saw the gap: brilliant technology that couldn't cross into enterprise reality.
Bruno Laureano
Co-Founder & Chief Technology Officer
The original architect of our Verifiable AI platform, Bruno is a pioneering engineer in agentic AI. He solved the fundamental enterprise adoption barrier by engineering the elegant decentralized architecture that became the core of Dooor, with deep expertise in decentralized systems and applied cryptography.
Bruno Laureano had built an award-winning AI agent but faced the classic barrier: enterprises wouldn't risk their IP with external AI. His solution was a decentralized architecture that allowed AI to run in cryptographically private spaces.
