About Obra

The work,attended to.

Obra puts Claude to work where it is needed most and trusted least: regulated businesses, where data cannot leave the building and every action needs a receipt. We do not hand you the AI. We employ it, run it, and answer for it.

The team

A small team, accountable by name.

Obra makes AI accountable, so the people behind it are named too. You always know who stands behind the work.

Francisco Ribeiro
Founder

Francisco sets Obra's direction and builds it in public. He is not an engineer. He is the proof of the thesis: with AI as the team, one founder can run a company.

Liliana Cipriano
Co-founder, Operations

Liliana runs reception and property management on the ground. Her daily compliance work is where Obra's first proven workflow was born, and she keeps the product honest to how the job really works.

Vladimir Jirasek
Security Advisor

Vladimir Jirasek is a Chartered Fellow of the BCS and a security executive with over two decades of experience securing complex organisations across Europe and the Middle East. As the founder and principal consultant of Foresight Cyber, he specialises in aligning cyber risk management with business strategy, moving beyond compliance to true operational resilience.

Vladimir's expertise lies in high-stakes environments. His track record includes delivering critical national infrastructure defences, driving multi-million pound security transformations, and guiding financial institutions through rigorous PCI DSS and ISO 27001 certifications.

How Obra is built

Built with Claude, by a small team.

People ask what stack we used. Here it is, in the open. Francisco is not an engineer; the engineering is done with Claude, in Claude Code, and reviewed by people who secure critical infrastructure for a living. Over 125,000 lines of source, built this way.

The intelligence
  • Built on Claude (Anthropic)
  • Claude Agent SDK for the agent loop
  • Model Context Protocol (MCP) for typed connectors
  • The model is a swappable component
The engine
  • TypeScript and Node.js
  • Inngest for durable, resumable workflows
  • Playwright to drive the systems that have no API
  • Anthropic memory tool and prompt caching
The trust layer
  • Local-first: runs on your own machine
  • OS-level credential storage, never plaintext
  • Typed, tier-classified actions with human gates
  • A hash-chained audit trail you own

The model is the commodity. The accountable workforce is the product. Our moat is not the stack. It is the operation, the trust layer, and the workflows we accumulate.
