AI Tools & Engineering

Intelligence that
drives results.

Firelock builds bleeding-edge AI tools and software, from open-source developer infrastructure to full-stack engineering. We solve real problems with real technology.

Why Firelock

We're not your typical consultancy. We're the team you call when the stakes are high and the technology needs to be extraordinary.

AI-First Across Every Workstream

We don't bolt AI on as an afterthought. Every engagement, every deliverable, every decision is informed by intelligent systems that amplify human expertise.

Bleeding-Edge, Battle-Tested

We operate at the frontier of what's possible, then engineer it into production-grade solutions. Cutting-edge technology with enterprise reliability.

Quick On Our Toes

Lean teams, fast cycles, zero bureaucracy. We move at startup speed with enterprise polish. Your timeline is our timeline.

We build solutions for the enterprise.
We build infrastructure for the community.

When existing tools bottleneck our velocity, we build our own. Kin is our answer to a software substrate that should have been semantic before AI agents ever showed up.

Kin

The semantic system of record for software work. Kin makes the entity graph authoritative, lets agents connect through MCP, and keeps familiar file-based surfaces as projections instead of the source of truth.

  • Semantic Truth

    Functions, types, contracts, and relationships live in the graph as first-class truth instead of being reconstructed from flat files over and over.

  • Agent-Native Access

    Kin exposes more than 60 MCP tools so assistants can query semantic search, trace, context, review, and impact directly instead of spelunking through file trees.

  • No Forks Required

    kin-vfs projects normal files to any tool, Kin Editor adds focused VS Code UX, and Git coexistence keeps brownfield adoption survivable.
