We are a small, geek-driven team. In an era when AI makes tools universally available, the only remaining scarcity is taste — aesthetic judgment about architecture, obsession over detail, commitment to the long game. Nebutra benchmarks against top Silicon Valley R&D orgs: type-safe, observable, Edge-first, multi-tenant, open-source from line one. Not a slogan — this is our daily engineering discipline.
Across the three-layer evolution of the AI stack, our battlefield is the Harness layer — MCP/Skill, tool ecosystems, agent orchestration, A2A. This is where real engineering lives in 2025–2026.
The innovation frontier of large models expands outward every two years. 2022 was scaling weights; 2023–2024 was RAG and long-context engineering; 2025–2026, the real marginal value has shifted to the Harness layer — tools, protocols, workflow graphs, and agent infrastructure.
Nebutra Sailor treats Harness engineering as a first-class concern. We don't train foundation models, and we don't just do prompting — we ship production-grade Harness: MCP/Skill-driven agents, A2A protocols, observable workflow graphs, and a secure tool ecosystem. This is the next architectural coordinate of AI-native SaaS.
Every product designed for the AI era from line one. MCP Agent workflows, RAG retrieval, and multi-model gateways as first-class citizens.
Model Context Protocol + Skill packages as first-class citizens. Sailor ships an MCP server adapter, Skill registry, and sandboxed runtime.
Agent-to-Agent protocol — task routing, capability advertisement, tenant-isolated message bus. Agents collaborate like microservices.
Declarative workflow graphs — stateful nodes, replayable, observable. AI behavior is no longer a black-box prompt but a debuggable DAG.
Multi-model routing + compute scheduling. OpenAI, Anthropic, local OSS unified — dynamic switching by task, cost quota, and SLA.
Sailor is open-source end-to-end. We believe open ecosystems compound more than proprietary stacks.
Why open-source? Because we believe: in an accelerated era, proprietary edge evaporates in 6 months, while open-source compounds over a decade. It frees customers from vendor lock-in, lets the community harden our infrastructure, and subjects every commit to worldwide review. This is our most confident long-term bet.
Benchmarked against Silicon Valley standards — TDD, PPR, Edge-first, built-in observability. Engineering taste is what separates winners from losers.
Tests first. Red → Green → Refactor. 80%+ coverage required on every PR.
Next.js 16 Cache Components — static shell + streamed dynamics.
Deploy to global Edge nodes by default — CDN, data, and compute near users.
TypeScript strict + Zod runtime — contracts at both compile and runtime.
OpenTelemetry, structured logs, error tracking — wired from day one, never "later".
pnpm workspaces + Turborepo — share taste across apps, avoid divergent rot.
All code dual-reviewed by Claude + human, architecture decisions recorded as ADRs.
Great organizations should not drift into mediocrity and bureaucracy as they scale. When the Nebutra ecosystem and its incubated companies face rapid growth, the following three are the only non-negotiable principles of organizational evolution — each directly constraining hiring, governance, and resource allocation decisions.
Refuse to respond to complexity by piling on headcount or management layers. Every scaling problem must return to the two acceptable answers — raising the per-person ceiling, and raising AI automation depth.
Delegate standardized operations, testing, and internal flows to AI Agents. Reduce inefficiency, conflict of interest, and internal friction at the root by embedding governance logic as auditable code and systems.
Keep human cognition focused on the highest-value strategic insight, architectural innovation, and real delivery. Reserve scarce organizational resources for judgment and creativity that cannot be automated.
