Agents that survive production.

We design, build, deploy and debug autonomous AI systems — MCP servers, LangGraph state machines and deep multi-agent architectures — then instrument them so you always know exactly why an agent did what it did.

What we do

Four disciplines, one operating loop

Most teams can prototype an agent in a weekend. Getting one to run reliably, cheaply and observably for eighteen months is an entirely different engineering problem. That gap is our whole practice.

01

Build

Architecture first. We model your problem as an explicit state machine — nodes, edges, interrupts, checkpoints — before a single prompt is written. Deterministic control flow around a non-deterministic core is what makes agents debuggable later.

  • LangGraph
  • Deep agents
  • A2A
  • Planner / executor
  • Tool schemas
  • Human-in-the-loop
02

Deploy

Agents are long-running, bursty, stateful and expensive — a genuinely hostile workload for ordinary request/response infra. We ship durable execution, queue-backed workers, streaming transports and blue/green rollouts gated on evaluation suites, not vibes.

  • Kubernetes
  • Durable workflows
  • Autoscaling
  • Canary + eval gates
  • Multi-region
03

Debug

Our specialty. We take traces from agents nobody can explain any more and find the actual failure — a malformed tool schema, a poisoned memory write, a retry storm, a silent context truncation — then prove the fix with a replayable regression suite.

  • Trace forensics
  • Replay harness
  • Root-cause reports
04

Maintain

Models deprecate, APIs drift, prompts rot. We run the on-call rota, keep the eval suites honest, migrate you between model generations without regressions, and publish a monthly reliability and cost report your CFO can actually read.

  • 24/7 on-call
  • Model migrations
  • Cost governance
05

Observe

OpenTelemetry spans on every node, tool call and token. Cost, latency and quality attributed per run, per customer, per prompt version — so regressions surface in a dashboard instead of a support ticket.

The toolbox

Every layer of the agent stack, in three dimensions

We are deliberately polyglot. The right runtime for a latency-bound voice agent is not the right runtime for a nightly batch of ten thousand document extractions. Drag the constellation to explore.

Our stack

LangGraph

Durable, checkpointed state machines for agents that need to pause, branch, resume and be inspected.

How an engagement runs

The agent lifecycle

01

Model the problem

We map the workflow into an explicit graph: what the agent is allowed to decide, what must stay deterministic, where a human approves. Ninety percent of agent failures are scoping failures wearing a prompt costume.

  • Task decomposition
  • Tool inventory
  • Failure budget
02

Wire the tools

Every capability becomes a typed, versioned, individually testable tool — usually an MCP server so the same integration works across Claude, your IDE and your production runtime. Strict schemas, idempotency keys, and errors the model can actually act on.

  • MCP servers
  • A2A handoffs
  • AG-UI events
  • Idempotency
03

Evaluate before you ship

A golden dataset from your real traffic, LLM-as-judge scoring calibrated against human labels, plus adversarial cases for injection and loop behaviour. No prompt change merges without a green run.

  • Golden sets
  • Regression gates
  • Red teaming
04

Deploy durably

Checkpointed execution so a pod eviction at minute forty doesn't lose the run. Streaming to the client, budget ceilings per invocation, and a kill switch that actually works mid-flight.

  • Checkpointing
  • Budget caps
  • Kill switch
05

Observe & iterate

Traces flow into OpenTelemetry. Every anomalous run is replayable locally against the exact tool responses it saw. Weekly, the worst traces become new eval cases — the loop closes and quality compounds.

  • OTel traces
  • Run replay
  • Eval flywheel
01 / Model
Diagnostics practice

We fix the agents that nobody can explain

Bring us a trace and a symptom. These are the six failure classes behind the overwhelming majority of production incidents we're called into — select one to see how it presents.

capable trace --run r_8f21c4 --follow Live

Our fix: a hard step ceiling with a progress heuristic — if no new information enters the scratchpad across two cycles, the graph routes to a summarise-and-escalate node instead of re-planning.

Interoperability

Three protocols. One architecture.

An agent that only speaks to your own code is a dead end. The industry settled on three standards — one for tools, one for other agents, one for people — and we build against all of them, so your system stays pluggable as the ecosystem keeps moving underneath it.

  • MCP Agent → tools & data

    Model Context Protocol turns your internal systems into typed, scoped tools any model client can call. We ship servers over stdio and streamable HTTP, with OAuth-scoped access, contract-tested schemas and gateways in front of the whole estate.

    Tools & resources Elicitation Registries
  • A2A Agent ↔ agent

    Agent2Agent lets your agents discover and delegate to agents you do not own or control. We publish signed Agent Cards, negotiate capabilities, and put timeouts, retries and settlement logic around every cross-vendor handoff — because a peer agent will fail.

    Agent Cards Task delegation Trust boundaries
  • AG-UI Agent → human

    An agent nobody can watch is an agent nobody trusts. AG-UI streams tokens, tool calls and state deltas into your front end over a standard event channel, so you get live progress, shared state and human approval gates without a bespoke websocket protocol.

Engagement shape

From first call to steady state

No six-month discovery phase. We aim to have something running against your real data inside the first fortnight, because that is when you learn what the agent actually needs to be.

Book a scoping call
01

Technical discovery

Week 1

Two working sessions with your engineers. We leave with a graph diagram, a tool inventory, a failure budget and an honest answer on whether you need an agent at all — sometimes the correct recommendation is a workflow.

02

Thin vertical slice

Weeks 2–3

One complete path end to end, on your real data, in your VPC. Instrumented from day one so we're measuring rather than guessing.

03

Harden & evaluate

Weeks 4–7

Golden datasets, adversarial suites, cost ceilings, fallbacks and the human-escalation paths. This is where an impressive demo becomes a dependable system.

04

Production rollout

Weeks 8–10

Shadow mode, then a percentage ramp with automatic rollback on eval regression. Your team runs the deploy; we're on the call.

05

Handover or retainer

Ongoing

Full documentation, runbooks and pairing until your team owns it — or we stay on as the agent reliability function. Both are fine; we're not trying to become load-bearing.

Questions

Before you get in touch

The things engineering leaders ask us on the first call.

No. LangGraph is our default for stateful, long-running agents because checkpointing and interrupts come for free, but we ship plenty of systems on plain SDK calls, on CrewAI, on Pydantic AI, or on a bespoke orchestrator in Go when latency demands it. The architecture decides the framework, not the other way round.
All three of the ones that matter, because they solve different problems. MCP is how an agent reaches your tools and data. A2A is how it delegates to agents you do not own — signed Agent Cards, capability negotiation, and real timeout and settlement handling around every cross-vendor handoff. AG-UI is how it streams progress, state and approval requests into your front end. We implement them as servers and as clients, keep them current as the specs move, and we will happily tell you when a plain HTTP call is the more honest answer.
Yes, and roughly two thirds of our engagements are structured that way. We deploy into your cloud account, use your model endpoints — including self-hosted open-weight models via vLLM or Bedrock — and keep traces in your own observability stack. We can operate entirely on your hardware if regulation requires it.
Almost always distribution shift in the inputs plus a missing failure path. Test data is clean and short; real data is messy, long, multilingual and adversarial. Without per-node instrumentation you cannot see which step degraded, so the whole thing looks randomly broken. A focused diagnostic usually identifies the specific node within the first week.
Four levers, in order of impact: routing cheap deterministic steps away from the model entirely; aggressive prompt-prefix caching; model tiering so a small model handles classification and a frontier model only handles genuine reasoning; and hard per-run token ceilings with graceful degradation. Median reduction across our engagements is sixty-one percent with no measured quality loss.
You do, unconditionally, from the first commit. We work in your repository, under your license, with your review process. There is no runtime of ours you become dependent on and no per-seat platform fee waiting at the end.
Python for the orchestration and evaluation layer where the ecosystem is strongest. TypeScript for anything that touches a browser, an edge runtime or an MCP client. Go and Rust for high-throughput tool servers, gateways and streaming transports where GC pauses or per-request overhead matter. Java where an enterprise integration layer already lives there.
Diagnostic work typically starts within a week — we hold capacity for incident response. Longer embedded builds depend on pod availability and are usually two to four weeks out. If something is actively on fire in production, say so in the first line of your message and we will triage it the same day.
