01 The problem Australian SMB · 2026

Your team is doing work a system should do.

01 / Leads

Enquiries sit in an inbox for hours

By the time someone gets to it, the prospect has already moved on and booked with whoever answered first.

02 / Follow-up

Renewals and referrals leak

Renewals, re-engagement and referrals go missing because nobody is tracking them and no system is either.

03 / Admin

More admin time than client time

Data entry, chasing, reporting, compliance documents. The work that pays sits behind the work that does not.

04 / Tools

Paying for a CRM, using a fraction of it

Nobody was trained and nobody maintains it. AI so far has been a chatbot demo that changed nothing.

02 What we do AI systems · not bots

We engineer AI systems. Not bots glued to broken processes.

An AI system is a piece of revenue work handled end to end: diagnosed, designed on paper, built in the tools you already run (HubSpot, n8n, your accounting and job platforms), documented, and handed over or run for you. AI earns its place inside the system or it doesn't go in.

Answer

Leads answered in minutes.

Instant lead response and qualification, so every enquiry is captured, routed and replied to before the prospect has moved on. Quote and proposal automation behind it.

Retain

Follow-up that never forgets.

Renewal and re-engagement engines that track what a person otherwise has to remember. Referrals, renewals and dormant clients handled on schedule.

Reconcile

Admin that does itself.

Document classification and reconciliation, plus reporting that lines up with what you invoiced. The weekly number stops being an argument.

03 Software we ship Our own products · shipped

We build AI software for the market, not just for clients.

Alongside client work we design, build and run our own SaaS. It's why the advice holds up: we've carried the pager on production AI systems, so we know which automations are worth their maintenance cost.

SaaS · Agency sales Live

Propel

Turns an agency's discovery notes into an interactive client deal room instead of a PDF. Live pricing, inline questions, and analytics on what actually got read.

SaaS · Construction payments Pre-launch

ClaimClock

Turns a NSW subcontractor's invoice into a valid payment claim under the Security of Payment Act and runs the statutory response clock, working shown.

SaaS · Partner delivery Live

Delivery Arc

A delivery operating system for HubSpot partners and implementation agencies. Keeps findings, approvals, evidence and handover in one arc instead of scattered across decks and Looms.

04 Who it's for Three industries

Built for three industries we know cold.

Financial services

Insurance, planning, fintech

Commissions, trails, compliance workflows and renewals. The playbook for anywhere money moves on a schedule.

Trades & construction

Quote-to-job and payment claims

Quote-to-job pipelines, speed-to-lead and payment claims, whether the job is a service call or a full build.

Health & medical

Practices and owner-led operators

Recalls, intake, and systems built to survive the owner taking leave.

Outside these three? Book the call anyway. If the patterns don't transfer, we'll say so and point you to someone better placed.

05 Method v3.2

One method. Four stages. Deliberately boring.

Nothing ships without a diagnosis. Nothing is built we can't hand back to you. Nothing is automated we can't switch off without breaking revenue.

01 · Diagnose
2 to 5 business days

The AI Readiness Audit.

A 90-minute working session plus a written pack: systems map, leak-ranked fix list, AI opportunity matrix and a prioritised 90-day roadmap. Fixed price, quoted on your readiness call, and credited in full against any build you proceed with. Usable whether or not you go further.

OutWritten pack · 90-day roadmap
02 · Architect
1 to 2 weeks

Modelled on paper first.

Lifecycle, pipelines, handoffs and integrations drawn out before a single property is created. Reviewed with you and signed off in writing before anything is built.

OutSystem design doc · ERD
03 · Build
2 to 6 weeks

Source-controlled. Documented as we go.

Everything versioned. No hidden Zaps, no undocumented custom code left behind by someone who has since left.

OutProduction system · runbooks
04 · Operate
Ongoing · optional

Hand it back, or we run it.

We train your team and write the SOPs. Run it yourself, or we run it on a fixed monthly fee. Either way, nothing breaks if we leave the room.

OutSOPs · monitoring · handover
The rule

"If a system can't survive its operator going on leave, it isn't a system. It's a person doing a job in a costume made of software."

07 Frequently asked questions Plain answers

Questions we get every week.

What exactly is an AI system?

A piece of revenue work handled end to end, rather than a chatbot bolted onto the side of it. Take lead response: the system captures the enquiry wherever it lands, qualifies it, routes it to the right person, drafts the reply, books the appointment and writes the record back to your CRM. AI does the parts it is genuinely better at, like reading unstructured text and drafting. The rest is ordinary engineering. It is built in the tools you already run, documented, and you can switch any part of it off without breaking revenue.

How much does the audit cost?

Fixed price, quoted on the readiness call once we know the size of your stack and team. We don't publish a number because a five-person trades business and a forty-person brokerage are not the same audit, and a "from" price would just mean re-quoting you later. Whatever you pay is credited in full against any build you proceed with.

Who is Assembly Growth's typical client?

An Australian SMB with roughly 2 to 50 staff, a partly-configured CRM (usually HubSpot), automation that accreted rather than was designed, and no in-house revenue operations capability. We work with financial services, trades and construction, and health and medical practices.

What does the AI Readiness Audit include?

A 90-minute working session plus a written pack delivered in 2 to 5 business days: a systems map of where your revenue work actually happens, a leak-ranked fix list, an AI opportunity matrix showing where AI earns its keep versus where it won't, and a prioritised 90-day roadmap. Credited in full against any build.

Which CRMs do you build on?

HubSpot is our primary CRM. We also support Attio and Monday implementations. Integration middleware is built in n8n, which connects any CRM to your accounting platform, job-management system and compliance tools.

Where is Assembly Growth based, and do you work outside Sydney?

Assembly Growth is based in Sydney, Australia, and works with clients across Australia and New Zealand remotely. All discovery, build and handover work can be delivered remotely; on-site workshops in Sydney, Melbourne and Brisbane are available where useful.

Start with a clear picture of what's broken.

The AI Readiness Audit: a 90-minute deep dive plus a written pack, delivered the same week. Systems map, revenue leakage scan, AI opportunity matrix, prioritised 90-day roadmap. Fixed price, credited in full against any build.
