An AI agency in London that ships what it builds.
The Third Way Company pairs senior engineers with specialized AI agents to build production software, automate workflows, and upskill teams. Based in London, working with clients everywhere — automation for the repetitive work, humans for the judgment.

“AI agency” is what the search box calls us. What we actually are is a small engineering company: senior engineers directing specialized AI agents the way a principal engineer directs a team. The agents read code, draft, and test at machine speed; the engineers shape, review, and decide. You get the output of a larger team with the accountability of a small one — a named human owns your outcome.
If you are a London business weighing an AI agency against a consultancy or a freelancer marketplace, the honest comparison matters more than the pitch. Consultancies sell process and decks at enterprise prices. Freelancer marketplaces sell hours with no continuity. We sell shipped work: fixed-price milestones or a retainer, progress you can watch in days, and code your own team can extend without us.
What an AI agency does here
Software Development
From idea to production-ready applications: agents write the repetitive code, senior engineers own the decisions, and you get a shipped product with tests, CI, and a handover that sticks.
Learn more →AI Workflow Automation
We audit where your team’s hours actually go, automate the top workflows, and hand you before/after numbers. Human checkpoints wherever judgment matters.
Learn more →AI Upskilling Program
Your team learns to direct AI agents on your stack and your daily work — practical, tailored, and over in weeks, not semesters.
Learn more →AI Risk & Security Assessment
Shadow AI, data exposure, and agent risks mapped and addressed before they become incidents — the vendor-neutral version of the conversation.
Learn more →Agent Ship Week
One AI agent shipped to production in five days, at a fixed price. The natural first milestone.
Learn more →Legacy Archaeology
The system nobody understands, written down and verified in two weeks — or you pay nothing.
Learn more →London, honestly
We are based in London and work with clients wherever they are — remote-first, on purpose, because the agents do not care where the code lives and neither do the results. When a London engagement calls for a room — a kickoff, a workshop, the awkward meeting — we are there in person.
Much of our work maps onto this city’s default industries — law firms, financial services, logistics — each with its own proof points on the industries pages. If your world is one of those, start there; the conversation will be shorter.
How an engagement runs
We connect
A 30-minute call to understand the problem, the constraints, and what a great outcome looks like — including whether we are the right agency at all.
We shape
A concrete plan: scope, milestones, stack decisions, and a fixed price or retainer. No open meter, ever.
We build in the open
Short cycles you can watch — progress in days, not at the demo three months from now.
We ship and hand over
Launch, monitoring, documentation, and a handover your engineers will not curse us for.
The honest parts
The company is young. The engineering isn’t.
The Third Way Company was founded in April 2026. Judge the work, not the founding date: real engagements with named outcomes are on the work page, and we will tell you when AI is the wrong tool for your problem — we would rather lose an engagement than ship a bad fit.
Pricing you can read before you call
Every engagement is fixed-price per milestone or a monthly retainer, with transparent price bands published on the pricing page. If a competitor needs a discovery call to tell you what a thing costs, that is a fact about the competitor.
Questions we get asked
What does an AI agency do?
+
An AI agency applies AI — agents, automations, models — to a client’s actual work instead of talking about it: building software, automating workflows, and training teams. Ours does it with senior engineers directing specialized AI agents: the agents handle the repetitive work at machine speed, the engineers own the judgment calls.
Are you actually based in London?
+
Yes. The Third Way Company was founded in London in April 2026 and works remote-first with clients everywhere. London engagements can happen in person whenever a room is the right tool — kickoffs, workshops, the conversations that do not survive a call.
How much does an AI agency in London cost?
+
It depends on the shape of the work, not on mystery: fixed price per milestone or a monthly retainer, never an open meter. Transparent price bands for assessments, builds, and upskilling are published on our pricing page, and every engagement starts with a scoped quote before any money moves.
How is this different from a consultancy or a dev agency?
+
Consultancies sell process and layered staffing at enterprise prices; dev agencies sell hours with a markup. We are a deliberately small senior team amplified by AI agents, so you get the output of a larger team while a named human stays accountable for the outcome. The full argument, trade-offs included, is on our thesis page.
Do you work with clients outside London?
+
Yes — remote-first, with clients wherever they are. The London page exists because that is where we are based and where much of our work is, not because there is a radius on the map.
Can you work with our existing codebase and team?
+
Yes. If the system is old and poorly documented, our Legacy Archaeology sprint writes it down and verifies the result first — a two-week, fixed-price blueprint you keep regardless of what happens next. After that we can build alongside your team, or hand everything over and walk away cleanly.
