01 - Our services

Five ways we give the week back.

Five capabilities, each already carrying revenue inside a mid-sized company that answers for the number every month. None of them is a chatbot bolted onto a website.

01

AI Opportunity Mapping

Business consulting first: we find where AI actually earns its place in your operation, size what it is worth, and sequence the build against it.

Discovery · Business case · Roadmap
02

Revenue Systems Engineering

The path from enquiry to booked revenue, engineered and instrumented - answered in seconds, qualified against your criteria, routed to the person who closes it.

Speed to lead · Qualification · Routing
03

Pricing & Quoting Engines

Quotes priced off your own book, with the arithmetic kept away from the model - so it flags what it isn't sure of instead of inventing a number.

Price books · Document intake · Human review
04

Outbound & Pipeline Engineering

Built pipeline for companies where a single deal is worth six figures: the targeting, the sequences and the call layer, run as one system into your calendar.

Targeting · Sequences · Meetings booked
05

Automations & Document Intelligence

The paperwork your team retypes between systems - read once, checked, and actioned automatically, with a person on anything the system flags.

02 - How we work

Every build runs through four stages.

Each one hands over a single thing and opens the next. The gate at stage two decides whether the build happens at all - scored on numbers agreed before it starts.

This is the part nobody else does. Most agencies sell you the build and find out afterwards.

Opportunity
01

Find

Method
  1. Map where the money leaks today
  2. Score what AI would actually recover
  3. Rank it against what it costs to build
Deliverable One ranked opportunity with the business case behind it, and a fixed scope.
Proof gate
02

Prove

Method
  1. Build the smallest working version
  2. Run it against your data, not a demo
  3. Check the economics hold
Right on your recordsYour jobs · not a benchmark
Holds at your volumeReal load · measured
Survives the messy onesMissing details · odd formats · edge cases
Pays for itselfCost per job · against the agreed floor
Every check scored against numbers agreed before the run. If it fails, you don't buy the build.
Production
03

Ship

Method
  1. Wire it into the tools you already use
  2. Put a human in front of anything that reaches a customer
  3. Deploy it so it stays up without you
Deliverable A working system your team owns and can operate without us.
Against baseline
04

Measure

Method
  1. Track it against the number we agreed at the start
  2. Fix what drifts
  3. Expand only where the evidence says to
Deliverable Live performance measured against your own baseline - and the changes it justifies.
03 - Why we exist

AI - built by people who run the business too.

We are not a lab. We operate the systems we build - carrying real revenue, inside businesses we answer to every month. That is why we can tell you which work AI pays for and which work it quietly makes worse.

Proven
We test it on your data before you buy the build
Operated
We run what we ship - the same as we do our own accounts
Sized right
Built for companies doing $5M+ - big enough that the bottleneck costs real money, and close enough to the work to change something this quarter

First we could measure it properly. Then we halved it.

R20 → R9.58
Cost per lead, against the same audience
R240 → R120
Cost per conversion, once every conversion was actually being counted

The win here was measurement before creative. With tracking systemised across the whole funnel, the optimisation finally had something true to optimise against.

  • A ranked shortlist, costed
  • The number we'd measure against
Start with Find

Prove

The gate. Nothing gets built until this passes.
Priced to the proof

We build the smallest working version and run it on your data. If it doesn't hit the numbers we agreed, you don't buy the build.

  • A working proof on your own records
  • Measured against the agreed target
  • A straight yes or no on going further
Start with Prove

Build & Run

Only after the proof clears.
Priced to what it returns

07 - Our story

We run the systems we sell.

Our systems run in construction, home services, financial services, solar and early-stage software. Every one of them sits inside a company doing $5M or more, where a wrong number costs a real job and there is no committee to absorb the mistake. That constraint set the standard we build to, and we have not relaxed it since.

What we are actually good at is keeping the model away from the arithmetic. It reads, retrieves and routes. Anything with a right answer gets computed. The reliability lives in the structure around the model, in the retrieval, the approval gates and the measurement, which is why our systems keep working when the models underneath them change.

We are not researchers and we are not a lab. We are operators who got tired of watching capable companies lose their week to work a machine should have done. That is the whole business: find that work, prove a machine can do it on your numbers, then build the thing. The first company we did it in was our own - Only Big Jobs still runs on this stack. We add people as the work demands it, and a founder stays on your account either way.

Why we prove it before you buy it

A model that performs in a demo can still be wrong on your actual jobs. Five things settle whether an implementation holds, and every one of them is decided before anyone picks a model.

A tool that says "I don't know"

The hardest part of a quoting engine is not the pricing. It is engineering the refusal - getting it to stop and ask when the job description does not actually specify the work.

Where the week actually goes in a $10M business

Before we build anything we count the hours. The same three jobs come back every time, none of them is the one the owner expected, and only two are worth automating.

10 - FAQ

The questions we always get.

What does "proven by data" actually mean?

We test it on your records before you pay to build it. We agree a number up front - accuracy, cost per job, hours returned, whatever the business actually cares about - then build the smallest working version and measure it against that number on your own data. If it misses, you don't buy the build. Most firms let you find this out after the invoice.

Where do we start?

With whichever question you cannot answer yet. If you know something is expensive but not what to fix first, start with Find. If you already know the bottleneck and want to see whether a machine can actually handle it on your records, skip to Prove. Nobody starts with the build, including us, because until a proof exists neither side can price it honestly.

What stops it making something up?

Three ways, in order. We keep the model out of the arithmetic - pricing, eligibility and anything else with a right answer is computed deterministically, and the model only reads and routes. We engineer the refusal: the system is built to stop and flag when it is outside what it was proven on, rather than produce a confident guess. And autonomy is scoped per action - anything a customer or a payment sees goes past a person first. That boundary is written into the spec before the build, not discovered in production.

What happens to our data?

We work on the smallest slice that proves the point, we don't train third-party models on your records, and everything we build runs inside accounts and infrastructure you own. Where a proof needs live data we'll agree the scope and handling in writing before anything moves.

Will it integrate with the systems we already run?

Usually yes - and where it can't, it doesn't need to. Some of what we build sits alongside your stack and hands your team the output rather than writing into it, which means nothing you depend on can break and nobody has to approve an integration to get value. Where a true integration is worth it, that's scoped in Build & Run.

Who actually does the work?

A founder owns your engagement, start to finish. Yazan builds and Seanie runs the commercial side, and neither of those gets handed to someone else. As the work grows we bring in specialists behind them, but you will not be introduced to a founder and then passed to an account manager, because the person who agreed the number is the person answerable for it.

Are we too small for this?

Our work lands hardest from roughly $5M in revenue upwards - big enough that a manual bottleneck is costing real money every month, and where you can still decide to change it without a steering committee. Below that the numbers rarely justify the build.

What happens when it gets something wrong?

It tells you. The system flags what it isn't confident about instead of guessing, and anything customer-facing passes a person first. A tool that quietly invents an answer is worse than no tool, and it is the single fastest way to lose a team's trust in the whole programme.

What are we going to pay?

Find is fixed scope. Prove is priced to the proof. Build & Run is priced to the outcome, because by then both sides know what the outcome is worth. Nobody signs a build cost before the proof - including us.

What happens if we stop working with you?

You keep everything: the system, the source, the data and the documentation to run it without us. Nothing is hosted on our account, and there is no key we hold that turns it off. We would rather earn the next month than trap you in it.

11 - Contact

Find out if it is even worth doing.

Half an hour with a founder, not a sales rep. You bring the part of the week that keeps going wrong, we tell you straight whether a machine fixes it, what it would cost, and what it would return. Nothing to prepare.

01

The part of your operation worth automating

We go through where the hours and the margin actually go, and name the one or two places a machine pays for itself. Specific to your operation, not a slide about industry trends.

02

What it would take to get there

How we would build it, roughly what it costs, and the number we would hold ourselves to. If it is a fit, that becomes the Find engagement. If it is not, you still leave with the map.

03

Whether we are the right people

We take on a deliberate number of clients so a founder stays on every one. If your problem is outside what we are good at, we will tell you on the call and point you somewhere better rather than sell you a project.

Plenty of these calls end with us saying the problem is not worth automating yet. That is a useful answer too, and it costs you nothing to get it.
