Software · AI systems · One AI employee

We engineer software that holds up live.

A London studio building production-grade websites, AI systems, and voice agents. Plus Glass, one AI employee you can watch at work.

How we work

We build software the way instruments are made: measured, documented, handed over clean.

Fast by default

We ship in weeks, not quarters. Lean scope, modern tooling, and a bias for production over demos.

Holds up live

Error handling, monitoring and fallbacks are built in from day one, not bolted on after launch.

Yours to keep

Source, infrastructure and documentation handed over clean. No black boxes, no vendor lock-in.

Capabilities

Software. Systems. Skills.

We build software and AI systems, then help your team put them to work. From a custom product to practical AI training, we shape the work around your business.

AI Automations

Repetitive tasks become reliable, multi-step workflows across your tools, with alerts, logs and safe fallbacks.

AI Agents

Internal assistants for support, ops and sales, grounded on your docs, with clear boundaries and a clean handoff to humans.

API Integrations

Connect tools and sync data properly. Webhooks, pipelines, auth, rate limits and error handling, done right.

Voice Agents

Answers calls, qualifies leads and handles bookings. After-hours coverage, transferring to a person when needed.

Landing Pages

High-conversion pages for offers and campaigns. Fast loading, clear messaging, analytics-ready structure.

Websites & Web Apps

Modern, responsive builds: clean front-end with a solid backend when needed, built to scale without drama.

Flagship · Glass

One employee. A live desk.

Glass is one AI employee for your business. You watch it work on a live desk, step in, and hand the work back. It also works before you ask, starting with a morning brief.

The Glass desk. On the left, the agent's own browser on a supplier portal order page, its cursor clicking Confirm delivery for the Thursday slot. On the right, the conversation: your request and three progress steps.

Voice brief transcript: Good morning. While you were away, I kept things moving. Your inbox is down to the three that actually need you. The Meridian contract came back overnight, and I have read it through and drafted two ways forward, with the one I would recommend flagged for you. Thursday's call is rebooked so it will not clash with the site visit, and the September numbers are reconciled to the penny. Nothing is on fire. Whenever you are ready, I will walk you through it.

Don't read about the voice. Hear it.

This is Aura, the voice your AI employee speaks in. Press the orb for a short brief.

One employee for the work you hand it. You can watch the desk whenever you want. Private is $199/mo founding. Team is $699/mo founding for up to 5 people. See pricing.

How we ship

Four stages. Clean handover.

  1. Day 0

    Scope

    One call. We define the problem, the spec, the deliverables and the budget. You get a written brief, not a slide deck.

  2. Week 1

    Build

    Weekly builds against the spec. You see real software every Friday, not a status update with no artefacts.

  3. Weeks 2 to 4

    Ship

    Production deploy with monitoring, error handling and fallbacks. We watch it live before we hand it over.

  4. Handover

    Own

    Source, infra and docs handed over. Your team can run it without us, though we stay on call if you want.

Selected work

Boutique by design.

We keep a small roster so every project ships on time, to spec, and runs in production for years.
