Factory3

Backstage

You run the show. We run backstage.

Your customers now arrive through AI agents as well as your website and app. Both are only as good as the data and APIs behind them. Back-end systems for UK price comparison, energy, and utility brands, built and run by us, long-term.

  • Your AI plans keep stalling on data you can't trust, or can't safely expose
  • Your team has inherited something fragile that nobody fully owns
  • You're running on spreadsheets or a system that's hit its limits

Free diagnostic: a Back-End and AI-Readiness Audit or a Build Blueprint. No cost, no obligation.

Is this page for you?

This is specifically for one kind of buyer.

Here's how to know if you're them.

This is for you if…

  • You're an engineering, product, or ops leader at a UK price comparison, energy, insurance, or broadband brand
  • You've been asked to "do something with AI", and the data or APIs it would need aren't ready
  • Your back-end is fragile, underdocumented, or owned by one person who is your single point of failure
  • You want a system that will still be running, properly maintained, in ten years, not sat on your team's backlog

This is NOT for you if…

  • You want an AI demo or chatbot prototype with nothing reliable underneath it
  • You need a front-end, marketing website, or mobile app
  • You're looking for a short-term contractor to embed in your team on day rates
  • You want to build it in-house and hand it back to an internal team. We build things we intend to run, permanently.

The offer

The system your users never see: the one your business, and every AI agent, runs on.

Your back office gets clean, reliable data. Your APIs are ready for your website, your app, and the agents that will use them. Your team stops firefighting. We build it, we run it, for the life of the product.

Building from scratch, or working around manual process?

Why work with Factory3?

Specialists who stay.

We already know
your system

We've spent 20+ years building for UK price comparison, energy, insurance, and broadband. We know the data, integrations, and reporting challenges, and how to make those systems AI-ready.

We stay when
your team changes

As your internal teams change, we remain a constant. Our longest client relationship is 15 years. We have survived multiple team reorgs, CTO changes, and product pivots and the system has kept running.

You get founders,
not juniors

Every Audit and Blueprint is carried out personally by Jason or Nic. We take on a small number of clients at a time specifically so we can maintain that standard.

30+

Active systems

Back-end systems we own and run on retainer.

15+

Years of partnership

Our longest client relationship, still active today.

200+

Daily data sources

Provider and partner data aggregated and cleaned daily.

Success stories

From audit or blueprint to years in production.

Started as: Back-End Audit

Broadband
availability API

15 years in production Powers all MONY Group broadband journeys Small monthly retainer

The API powering every broadband comparison across MoneySuperMarket, MoneySavingExpert, Decision Technologies, and Broadband Choices, rebuilt by us and running for 15 years.

Decision Technologies' availability checker had hit its architectural limits: slow, unreliable, and unowned. We redesigned the infrastructure and have managed it on a small monthly retainer ever since.

Started as: Back-End Audit

Energy tariff
management API

Years supporting MONY API-driven tariff workflows Human sign-off built in

We built and ran MONY's energy tariff interface for years.

As MONY moved to automate operations, we built an API for the main tariff workflows, so automation does the work and a person signs it off, instead of someone doing it all by hand.

Started as: Build Blueprint

Real-time cash
flow analysis

11 years in production Survived multiple CFO changes Flags underpayments

Bionic's commission cash flow went from manual spreadsheets to a real-time reconciliation engine, built in 2015 and still running today.

Bionic had no way to project what it expected to earn per contract or flag when providers paid short. We built the system that handles both, and have maintained it through multiple CFO changes.

Started as: Build Blueprint

Affiliate sales-feed replatform

Every major UK affiliate network Full change ledger In support and maintenance

Quidco's legacy affiliate sales-feed platform was replaced with a configurable system covering every major UK affiliate network, Awin, CJ, and Impact among them.

Click events are matched with sales data in real time, every change is tracked through a full ledger, and the platform is now in support and maintenance, fully documented and easier to run than what it replaced.

Started as: Build Blueprint

AI broadband
assistant

Address-level availability Up-to-date broadband deals Multi-provider comparison

An AI assistant that answers broadband availability questions from the same kind of live provider data we've run for 15 years, rather than guessing.

The agent queries clean availability APIs through MCP, so its answers are only ever as current as the data, and the data is something we've run reliably for years. Built for PAN, a broadband business we're shareholders in: we had our own money riding on it working.

More case studies available on request. Get in touch.

Our approach

Why Factory3 builds differently

We say "NO"
to the wrong scope

We push back on scope and requirements before a line of code is written. Every system we have taken over from another supplier was built by people who said yes to everything. That is how systems get fragile. We challenge budget and requirements up front because the cost of correcting a bad decision later is always higher.

We build it, run it,
and never hand it off

We build things we intend to run. Our longest client relationship is 15 years. We work on a small monthly retainer, not day rates, specifically because we are incentivised to build it right and keep it running. When your team changes, we remain.

Twenty years in your
sector, specifically

We have spent 20+ years building for UK price comparison, energy, insurance, and broadband. We know the provider data formats, the affiliate reconciliation problems, and the reporting patterns. We have already built what you are planning to build.

We build the plumbing,
not the demo

Anyone can build an impressive AI demo in a week. It's the data and APIs underneath that decide whether it's still right in year five. That's the part we build, and the part we stay to run.

Built on

Backed by 20+ years of proven capability

Affiliate data reconciliation

Unify affiliate/partner sales and click data, and replay it to Meta, Google, and your own reporting.

Messy data, live API

Turn inconsistent provider data into a clean, highly-available API.

High-traffic infrastructure

Cost-effective, scalable AWS architecture for millions of requests a day.

AI-ready APIs and MCP

Let AI agents query your pricing and availability data safely, through the same reliable APIs your front end uses.

Common questions

What you're probably wondering

What's actually in the Back-End and AI-Readiness Audit?

A written assessment covering what's solid, what's fragile, the key risks, whether your data and APIs are ready for AI agents, and what it would take to get the system to a stable, properly-owned state. Delivered as a document you can share internally. No sales pitch attached. No follow-up pressure.

What does "AI-ready" actually mean?

Your data is accurate and fresh enough for an agent to rely on, the right APIs exist, access is properly controlled, and an agent can use them safely, for example through MCP. Most teams find at least one of those isn't true yet.

Do you build the AI agent itself?

Where it helps, yes. We've built an MCP-driven broadband assistant on live availability data, and the APIs that let MONY automate its energy tariff workflows, with a human signing off the result. But our focus is the data and APIs underneath, so whichever model or agent you choose gets the right answer.

What's in the Build Blueprint?

A concrete architectural plan: the data model, the integration points, the infrastructure, the running costs, and what day-to-day operation looks like. Specific enough that your team understands exactly what's being built and why, before any commitment is made.

Do you sign NDAs?

Yes, always. Before any technical discussion begins.

What happens after I submit my email?

A founder (Jason or Nic) will reply within one working day to arrange a short call. We use that call to understand your system or situation, then deliver the Audit or Blueprint within 10 working days. At the diagnostic stage you deal directly with the founders: no middleman, no handoff.

We're mid-refactor or mid-migration. Does that matter?

No. The Audit reflects the current state of the system, including anything in progress. It will give you a clear view of where things stand and whether the current direction is sound.

What does engaging Factory3 cost after the free diagnostic?

We don't publish rates because they depend on what we're running. The Audit or Blueprint will include a cost indication as part of the deliverable, so you will know before any commitment is made. We work on a monthly retainer, not day rates.

We're not in price comparison or energy. Can you still help?

Our deep experience is in UK price comparison, energy, insurance, and broadband. If you're adjacent (fintech, data-intensive SaaS, or high-traffic B2B platforms), the problems are often structurally the same. Get in touch and we'll tell you honestly whether we're the right fit.
