About Sett Advisory

Why a marketing agency ended up doing this.

Sett Advisory grew out of Purple Thread's marketing work with builders and the Master Builders Association network. Working alongside construction businesses across Australia, we kept seeing the same thing up close: owners losing hours every week to manual admin, margin quietly leaking away through errors caught too late, and good businesses exposed to AI-enabled scams and untested vendor tools — with no one independent to help them sort the genuinely useful from the hype.

Builders don't need another pitch. They're already being sold five "AI-powered" tools a month. What they needed was someone on their side of the table — who understands how a construction business actually runs, who can tell the difference between a useful drill and an expensive gimmick, and who'll induct the role on their own jobs instead of leaving a login and a good-luck note.

So we built Sett Advisory as its own thing: a foundation for AI, laid properly. We assess where you're losing time and money, prioritise the handful of roles that pay off fastest, and induct them on your jobs — done for you.

You get the holes — without having to buy every drill in the shop.

Who's behind Sett

Built by a software strategist. Proven with an award-winning builder.

Darrell Weekes

Founder

Former Director of Strategy at Attaché Software, the Australian accounting and payroll software company — years spent making technology earn its keep inside businesses that couldn't afford for it to fail. Now he does the same for builders.

Through Purple Thread, Darrell is a strategic marketing partner to the building and mortgage industries in Australia, and to the National Association of Mortgage Brokers in the USA. The thread through all of it: making complex technology pay its way, in plain language.

Developed with a builder at the table

Every role on the roster was designed and tested alongside Colin Jewell, Managing Director of Jewell Builders, Goulburn — winner of nine major building awards, including the 2022 National Trust Heritage Award. Colin's rule was simple: if a role can't survive a real job, it doesn't go on the roster. Every role is put to work on real jobs before it's offered to anyone else.

Sett is what happens when a software strategist and an award-winning builder look at the same back office. Every role was designed with a builder — not just for one. And every role is put to work on real jobs before it's offered to anyone else.

The Foundation Check

Every recommendation passes the Foundation Check before it reaches you.

Anyone can ask an AI for a tool recommendation. The Foundation Check is the discipline that comes after: every recommendation is verified against the vendor's own numbers, tested hands-on where practical, pressure-tested by a second independent AI, and reviewed by a human before it reaches you. We accept no undisclosed vendor commissions — if we ever have a commercial relationship with a vendor we recommend, you'll see it disclosed in the recommendation itself. And everything we recommend must pass one non-negotiable test: you can sack them any time — and if you do, every position description, every standard and all your data walks out the door with you.

01

We map your actual problem.

Not a generic checklist — the specific hours you're losing and where.

02

We shortlist real candidates.

Roles worth recruiting — not just the loudest vendor with the biggest marketing budget.

03

We verify before we recommend.

Pricing, security, fit, and whether you can leave it cleanly — confirmed directly, never assumed.

04

We induct your first role.

Loaded with your jobs, your quotes, your standards — and, where practical, put to work in our own businesses before it ever reaches yours.

05

We double-check our own advice.

A second, independent AI pressure-tests the first — then a human makes the call.

06

We stay accountable after.

Every role on your roster gets checked against real results at 30, 60 and 90 days.

"You check the set-out before you pour. So do we."
