About Platform21

A business owner helping business owners get results from their marketing.

Why Platform21 Exists

I started Platform21 because I was tired of seeing business owners get burnt by agencies that over-promise and under-deliver.

After 25 years in digital marketing, I have seen the industry from every angle: agency side, client side, and as a business owner myself. I have seen what works and what does not. And I have seen too many businesses waste money on marketing that looks good on paper but does not generate actual leads.

The problems are predictable. Account managers who do not understand the work. Reports full of metrics that do not matter. Locked-in contracts that benefit the agency, not the client. And a fundamental misalignment between what agencies optimise for and what business owners actually need.

In 2024, I rebuilt Platform21 around AI-powered development. Not to replace expertise, but to amplify it. 15+ specialist AI agents handle research, copywriting, and code generation—while I focus on strategy, quality, and making sure every site actually works for your business.

Platform21 is my answer to those problems—a next-generation agency that delivers websites in weeks, not months.

Meet Matthew Sweet

Founder and Director

I bring 25 years of digital marketing experience to every project. But what matters more is that I also run a business myself.

As Director of EcoMow Sustainable Gardening, I understand the daily realities of running a small business: tight budgets, limited time, and the need for marketing that actually works. I am not theorising about what business owners need. I live it.

This dual perspective shapes how Platform21 operates. When I look at your marketing, I am thinking about your bottom line, not impressions or click-through rates. I measure success the same way you do: by leads and revenue.

AI-Powered Delivery

15+ specialist AI agents accelerate execution while human judgement controls strategy and quality. The result? Websites in weeks, not months—without cutting corners.

You Work Directly With Me

No account managers. No junior staff learning on your project. When you hire Platform21, you work directly with me on every aspect.

Project-Based Pricing

Pay for the project, not endless retainers. Clear scope, clear pricing, clear deliverables. No surprises.

I measure success by leads, conversions, and revenue. Not reports padded with impressions and page views.

Local Expertise

Based in Logan, Queensland. I work with businesses across South East Queensland including Brisbane, Gold Coast, and Ipswich.

Full Transparency

We are upfront about using AI because you deserve to know how your website is built. Every AI output is reviewed by humans before delivery.

My Philosophy

Transparency Over Everything

No jargon. No hidden fees. No surprise invoices. We tell you what we are doing, why, and what it costs before we do it.

Solve Problems, Not Sell Services

We start by understanding what you need, not by pitching what we sell. Sometimes the right answer is something we do not offer.

Quality Over Quantity

We work with a limited number of clients so we can give each one proper attention. Excellent work for a few, not mediocre work for many.

Long-Term Relationships

Many of our clients have worked with us for years. We build relationships based on trust and results, not contracts and sales tactics.
