fazer > falar. (do > talk.)
While others talk about AI, we ship. We're engineers turning AI into real competitive advantage. No pretty slides. No empty promises. Just results.
We build AI agents that operate any piece of software like a human expert. Just faster, and without mistakes.
| Service | What it Means for You |
|---|---|
| AI Development Consulting | Claude Code, Codex and Gemini deployed as development infrastructure inside your team. Context engineering, autonomous agents, sandboxing and governance baked in. From 30 days to 1. |
| Fast Testing at Scale | A subscription that handles your AI backlog in isolated, production-safe environments. We validate before you invest in development. Recent runs: 70,000+ people served and 1.2M+ WhatsApp messages processed in a 30-day window. |
| Special AI Projects | End-to-end engineering for custom AI. Modern stack (LangGraph, NVIDIA H100, Kubernetes, Cloudflare Zero Trust). Banking, industrial, events, retail and real estate. |
ROI doesn't come from technology alone. It shows up when we pair business expertise with tailor-made automations.
We open-source the building blocks behind our work, organised in three tracks.
An open-source stack for WhatsApp-first customer engagement, anchored on our actively-maintained Chatwoot fork.
