Adjoint

Infrastructure for the AI Era

We build principled infrastructure for AI agents. Research-led, evidence-based, open source first.

Definition.

For a linear operator A, the adjoint A† is the unique operator that preserves inner structure while changing perspective. We do the same for complex systems.

Services

Four pillars of expertise, each rare individually, unique in combination.

NixOS for Healthcare

Declarative, reproducible infrastructure for medical environments. FDA-compliant, zero configuration drift, complete audit trails. Proven across 20+ international proton therapy facilities.

AI Agent Infrastructure

Production infrastructure for AI agents. Nix-packaged for reproducibility, framework-agnostic, deployable edge to cloud. 38+ production agents built and running.

III

Documentation to LLM

Convert facility documentation to AI-queryable formats. Wiring diagrams, P&IDs, equipment manuals transformed into knowledge graphs. 70% faster troubleshooting.

Edge AI Architecture

AI agents deployed at the edge for sub-50ms latency. Cloudflare Workers, multi-cloud orchestration, 90% cost reduction versus traditional cloud.

About

Principled infrastructure, not ad-hoc features.

The world is entering an era where AI agents collaborate, communicate, and coordinate at scale. Most infrastructure was built for humans clicking buttons. We build infrastructure for autonomous systems.

Values

Principled Over Pragmatic

We understand the theory, then build correctly. This takes longer but creates lasting value.

Evidence Over Claims

Everything is verifiable. Everything has a URL. We show the work, not just state capabilities.

Open Over Closed

Open source by default. Knowledge sharing over gatekeeping. Community building over vendor lock-in.

Depth Over Breadth

We go deep on fewer things rather than shallow on many. Expertise compounds.

Research

Systematic research that feeds products, consulting, and open source.

Agent Orchestration

How do agents coordinate, communicate, and maintain state? We've analyzed LangGraph, Temporal, and custom orchestration patterns to understand the fundamental primitives.

Active research

Messaging Patterns

Request-Reply, Pub-Sub, Push-Pull, Exclusive Pair. Understanding the complete space of agent communication patterns and their trade-offs.

4 patterns documented

Delivery Guarantees

At-most-once, at-least-once, exactly-once. What guarantees can we provide, and at what cost? The theory and practice of reliable agent messaging.

3 guarantee levels

Infrastructure Components

Durability, checkpointing, message brokers, state stores, observability. What infrastructure do agents need in production? We're mapping the complete landscape.
