Live Q&As with Matthew a year

One subscription. The whole library, and the man who built it.

Six complete courses from day one

The full path from deciding to start through to leading a team, and putting AI to work across it: Starters, Operators, Demand, Profit, Leaders, and AI. All six available in full from the day you join.

A new course every month

BUILT for People is dropping next, and the library keeps growing month on month. Every new course is included the day it drops, with no upgrade fee.

A live Q&A with Matthew, every month

One evening a month, Matthew goes live online and answers member questions directly. Miss it and the replay sits in your library the next day. Members also get meet-ups, masterclasses, and specialist sessions.

Tools you put to work the same week

Every lesson hands you a scorecard, planner, or 90-day plan. You leave with the next move decided, in writing, and a deadline against it.

A community of people doing the work

Friday wins thread. Monday check-in. People at every stage from first idea to first hundred customers, talking honestly about what is working.

Built in New Zealand, for NZ business

NZ tax, NZ banking, NZ regulators, NZ market realities. Local context that the American business courses miss every time.

Access to Matthew

Once a month, Matthew goes live. Your question, his answer, no filter.

Most courses sell you recordings of someone you will never speak to. Williams Academy puts you in the room. Every month, Matthew runs a live online Q&A for members, and the questions come from you.

  • Live online, one evening a month, included in your membership
  • Submit your question ahead or ask it live
  • Replays in your library the next day
  • Matthew reads the community threads between sessions

Six courses, live now. A new one lands every month.

The library follows the path an operator actually walks, from the decision to start through to wealth that compounds. Matthew's fourteen years inside Williams Corporation supply the case studies. Start at the course that fits where you are.

● Live
Course 01

BUILT for Starters

The decision to begin. Six lessons to decide whether you should start your business at all: your real reason, the cost, an honest readiness score, the decision statement, and a 90-day launch plan.

● Live
Course 02

BUILT for Operators

Running the operation through its first three years. A pipeline, winning and pricing work, a weekly cash check-in, paying yourself, the first hire, and a one-page systems map.

● Live
Course 03

BUILT for Demand

Get known. Brand, audience, and the marketing engine that fills the pipeline, so the selling has somewhere to start. For the operator still chasing every job by hand.

● Live
Course 04

BUILT for Profit

Know your numbers. Margin, unit economics, pricing with the discipline to walk away from work that loses money, and forecasting your cash ninety days out.

● Live
Course 05

BUILT for Leaders

Growth needs people. Hiring as a repeatable system, setting and holding standards, the management rhythm, and the hard conversations, including with people close to you.

● Live
Course 06

BUILT with AI

Put AI to work. The four layers from a chat window to a team of agents, killing the admin that earns you nothing, running your leads and follow-up, getting the numbers right, and running the whole stack at once.

● Next up
Course 07

BUILT for People

The people side of growing. Whether the next hire should be you or revenue, a role costed four ways, what being an employer takes, the job brief, the first ninety days, incentives, and the checklist before anyone gets equity.

● Coming
Later in the library

BUILT for Investors

The wealth stage. Buying for the deal, structuring debt so it works for you, and building assets that compound beyond the operating business.

● Coming
Later in the library

BUILT for the Storm

For the operator carrying debt, staff, and exposure. Reading the downturn early, surviving when the funder wants its money, and what the recovery actually takes. Taught from lived experience.

Built by

Matthew Horncastle started Williams Corporation at 19, on the tools, with nothing in the bank.

Fourteen years later, Williams Corporation is one of New Zealand's largest residential developers, with more than 2,500 homes settled and over $1.3 billion of property delivered.

Williams Academy is the course library Matthew wishes had existed when he was twenty-three, second-guessing every decision, and trying to figure out whether to keep going. Honest, on-tools, no MBA jargon. The conversation you would have with someone who has actually done it.

This is the course library I wish I had at 23, when I was making it up as I went.

Questions worth asking.

How much is it, and what am I locked into?

$69 NZD a month, or $690 a year (two months free). You are charged when you join, and the first 7 days are fully refundable, no questions. You can cancel inside the member dashboard in two clicks, any time. Founding members who joined before 5 October 2026 keep $49 a month or $490 a year for as long as they stay subscribed.

I pre-registered. Can I still get the founding price?

The founding rate closed at the end of 4 October 2026. Members who joined by then keep $49 a month or $490 a year for as long as they stay subscribed. New memberships are $69 NZD a month or $690 a year, charged when you join, with the first 7 days fully refundable.

What courses are in the library now?

Six, in full: BUILT for Starters, BUILT for Operators, BUILT for Demand, BUILT for Profit, BUILT for Leaders, and BUILT with AI. BUILT for People is next, and a new course lands every month after that. Your subscription unlocks every course as it drops.

How much time does it take?

Lessons are short and built to be acted on, and every one ends with a tool you put to work. The library is designed to fit around a working week, and you set the pace: one lesson a night or a course over a weekend both work.

Is this only for property developers?

No. Matthew built Williams Corporation in property, but the Academy is built around founder decisions and frameworks that apply to any small or medium business in New Zealand. The property stories are the case studies, the lessons are the business.

How is this different from other online business courses?

Most online business education sells one course at a time and is made for American or Australian markets. Williams Academy is one subscription for the whole library, every lesson ends in a worksheet you act on, and it is taught by someone who built his company here, inside NZ tax, banking, and consenting realities.

Will Matthew actually show up to the live sessions?

Yes. He runs a live online Q&A for members every month and the replays go into your library. He also reads the community threads between sessions and replies to questions members raise.

What if I decide it is not for me?

Cancel inside the dashboard at any time. Inside the first 7 days of joining, ask for a full refund of everything you have paid, no questions. After 7 days, you keep access to the end of the period you have paid for and that is it.

Doors are open. Start where you are.

Whether you are deciding to start, drowning in a busy business that pays you nothing, or leading a team through growth, the library has a course for the stage you are at.
