Tech stack

Multi-model. No vendor lock.

The AI-native stack we use on every engagement. Claude Code + MCP + Cowork as the substrate. Claude, OpenAI, Gemini, Cohere, Meta, LLaVA, LangChain + open weights — chosen by task. Underneath, a battle-tested engineering stack proven across 700+ projects.

01 · AI-native substrate

The nervous system of the engagement.

These aren't "tools we use sometimes." They're the continuous substrate the entire delivery runs on. If they're not active from day zero, we aren't doing AI-native — we're doing AI-assisted, which is a different thing.

01 · Context

Claude Cowork

Shared memory across all AI agents and humans on the engagement. Every artifact, meeting transcript (via Plaud), architecture decision, and PR enters the context and is available to any participant — AI or human.

02 · Access

MCP — Model Context Protocol

AI agents read and act on real systems: GitHub, Jira, cloud consoles, data warehouses, staging environments. No humans in the middle copy-pasting context.

03 · Engineering

Claude Code

The default pair-programming tool. Every engineer pairs with Claude Code on every task. AI review on every PR before human review. Non-negotiable discipline.

04 · Routing

Multi-model router

Each task goes to the best model. Claude Opus for deep reasoning. Haiku for fast loops. OpenAI / Gemini / Cohere / Meta / LLaVA / open weights for specific strengths. Implemented with LangChain + custom code.

02 · AI providers

The nine models we use.

We're not an "Anthropic shop" or an "OpenAI shop." We're an AIFirstCompany — and that means freedom to pick the best model per task, with no exclusive contracts or forced loyalties.

03 · Common engineering stack

Battle-tested across 700+ projects.

Our stack is optimized for banking, government, and infrastructure — where stability and scalability matter more than fashion. We adapt to the client's stack when it makes sense.

The stack is half the story. The other half is how we operate it, how we pick models, how we enforce human oversight.
