Agents that earn their keep,
not just demo well.

We design, build, and operate production-grade AI agents on top of OpenAI, Anthropic, Gemini and LiveKit. Voice, chat, multi-step task agents — every one ships with an eval harness, cost ceilings, and a route into your existing systems.

What we build

Four shapes of agent,
one engineering discipline.

We use the same eval-first playbook across every surface — voice, chat, multi-step. The shape of the agent changes; the engineering doesn't.

Voice

Voice agents

LiveKit + Twilio front-ends with sub-second latency. Drop-in replacement for tier-1 call handling — turn-taking, barge-in, graceful handoff to a human when the agent isn't sure.

  • Real-time speech-to-speech
  • Tool-calling into your CRM / dispatch
  • Per-call cost ceilings, fail-closed
Chat

Chat copilots

Inline assistants and standalone chat surfaces that retrieve from your data, write back to your systems, and cite their work. Embedded in your product or as a standalone surface.

  • RAG over your knowledge base
  • Function calls into your stack
  • Cited, audit-able responses
Multi-step

Task agents

LangGraph state machines for workflows with multiple turns, branches, and escalation paths. Predictable where you need it; flexible where you don't.

  • Deterministic guardrails
  • Human-in-the-loop escalation
  • Full reasoning trail per case
Operate

Eval harnesses

Every agent we ship comes with a CI-wired eval set built from your real cases. Regressions get caught at PR time, not by your customers in production.

  • Replayable case corpus
  • Multi-turn scoring built-in
  • Model-bump regression tests
How we work

Kickoff to production,
in six weeks.

Every engagement targets a live, evaluated agent in your stack — owned by your team when we walk away. No demos, no lock-in.

01Week 1Discovery

Map the workflow we're improving

We sit with the people doing the work today — your product team, your end users, your operators. What does the workflow look like? Where does it break? Outputs: agent spec, success metrics, and a clear build/buy decision before any code is written.

02Week 2–3Prototype

A working agent in your stack

An evaluated v0 against your real data — not a demo on slide deck. Run live queries, see real outputs, pressure-test before we commit to production hardening.

03Week 4–6Productionize

Hardening for production traffic

Function calls, retrieval pipelines, evaluation harness, fallbacks, audit logs, cost ceilings, role-based access. The system your platform can run in production from day one.

04Ongoing or finalHand-off

Hand-off and optional retainer

Documented system, trained team, full source code. From here: clean exit, or 3-month retainer at £8-12K/month for continuous AI development and weekly evals.

Tech stack

No tool dogma.

How long until we have something in production?

Most engagements ship a live, evaluated agent in four to six weeks. We don't ship demos — when an agent goes live, it's instrumented, eval-covered, and has a documented hand-off path to your team.

Which model providers do you use?

Whichever ships. We've put OpenAI, Anthropic, Gemini, Mistral, and self-hosted models into production in the last 18 months. We pick based on latency, cost, and accuracy on your eval set — not on vendor relationships.

Do you build the eval harness, or just plug one in?

We build it. Every engagement starts with a corpus of real cases pulled from your support inbox, ticket queue, or transcript archive. That corpus becomes the eval set, wired into CI, scored on every model bump.

What happens when you walk away?

Your team owns the system. We hand off code, tests, runbooks, the eval corpus, and a roadmap. Optionally we stay on retainer to run weekly evals and respond to regressions — but it's an option, not a lock-in.

Can the agent integrate with our existing systems?

Yes. Most agents we ship have function-calling into a CRM, EHR, dispatch system, or internal API. We use whatever you already have — REST, gRPC, queues, webhooks — and write thin adapters where we need to.

How do you handle data privacy and compliance?

We default to your hosting (your AWS / GCP / Azure account). We've shipped HIPAA-aligned and GDPR-aligned agents. PII handling, retention policies, and audit logging are designed in from week one, not bolted on later.
