A visitor to King Kong’s website is not greeted like a procurement officer. The copy swears, teases, promises “steroids for business” and keeps pointing at a button. It sounds like a late-night infomercial rebuilt by people who know what a conversion rate is. That tone is not decoration. It is a demonstration of the Melbourne company’s central belief: marketing exists to make a prospect act, and every step before the sale should be accountable to the one after it.
Founded by Sabri Suby in 2014, King Kong is a performance-marketing agency with a second life as a business-education platform. Companies can hire its team to manage customer acquisition, or owners can buy the books and training that explain versions of the same methods. Across both, the offer is consistent: identify a valuable audience, buy or earn its attention, sharpen the sales argument, remove friction from the page, and follow up until interest becomes revenue.
01 / The proposition
A guarantee with a qualification form hiding inside it
King Kong’s sharpest differentiator is a conditional guarantee. For businesses already running profitable Google or Facebook ads, the agency says it will build a new funnel, write new advertising and improve an agreed metric - conversion rate, cost per lead or return on ad spend - by 30 percent within 90 days. If it misses, it says it will keep working without its fee until it succeeds. The client still pays the media bill.
That last paragraph does three jobs. It transfers some performance risk to the agency. It filters out businesses without a working offer or comparable campaign history. And it lets King Kong control the creative and funnel elements needed to influence the result. The public terms are careful about apples-to-apples conditions such as product and season. The promise is therefore less a casino bet than a tightly bounded operating contract.
Thirty percent improvement within 90 days applies to qualifying, already-profitable campaigns and comparable conditions. Ad spend remains the client’s responsibility.
Most agencies list channels. King Kong lists outcomes, then uses the channels as parts. Paid search captures declared intent. Paid social creates and retargets demand. SEO builds durable discovery. Landing pages and conversion-rate optimisation determine whether attention survives contact with the offer. Email and CRM automation handle the prospects who are interested but not ready. Analytics sends the evidence back to media buying. The point is not that any one capability is rare. The point is that the agency wants responsibility for the connections between them.

02 / The customer
Built for the owner who has traffic, ambition and a leaky bucket
The useful King Kong customer is not defined only by company size. It is a business with enough demand, margin and operational capacity to scale. Public case studies span home building, aged-care finance, food, furniture, education, professional services and e-commerce. Named examples include Metricon, My Muscle Chef, Original UGG Australia, Electrolux Professional and Koala. Some are local operators. Others are national or multinational brands. The recurring problem is an acquisition system that produces too few leads, converts too little traffic or cannot scale without making each customer uneconomically expensive.
King Kong says its work has covered 1,067 industries and niches and reports A$7.8 billion in client revenue generated. Those are company-reported aggregate figures, useful as signals of breadth rather than audited proof of causality. Its site also describes a platform of roughly 200,000 customers across 136 countries. That wider number appears to include the people reached through training and education, not merely companies paying an agency retainer.
The variety matters because performance marketing is a pattern-recognition business. A search campaign for a builder cannot be copied into a meal-delivery account, but the diagnostic sequence travels: find intent, calculate allowable acquisition cost, isolate the bottleneck, test a stronger message and watch what happens after the click. King Kong’s accumulated advantage is less a secret ad format than a large library of things that failed, worked or stopped working at scale.
03 / The machine
One playbook, sold two ways
The company’s business model has two visible engines. The agency earns fees for managed strategy and execution across media, search, websites, funnels, creative and automation. The education side packages growth methods in books, courses and training programs for coaches, consultants and service businesses. Suby’s 2019 book, Sell Like Crazy, became both a product and a remarkably efficient introduction to the brand’s worldview.
This hybrid expands the addressable market. A mid-sized company can outsource the work. A solo consultant who cannot justify a multi-channel team can learn the framework. Education also warms the agency’s future pipeline: by the time a reader requests a call, the vocabulary and philosophy are familiar. Content is doing the first portion of the sale.
The company remains privately held and has described itself as bootstrapped. In a 2017 interview, Suby said he started without funding, venture capital or a safety net and had grown the agency beyond A$10 million in revenue. That history helps explain the obsession with cash-producing activity. A bootstrapped services company cannot postpone unit economics until a later financing round.
04 / The market
Between the specialist shop and the global network
King Kong sits in the crowded middle of the marketing market. Below it are freelancers and channel specialists who may provide deeper focus at lower cost. Beside it are Australian performance agencies such as Webprofits, Online Marketing Gurus, Megaphone Marketing and Impressive. Above and around it are global networks, consultancies and in-house growth departments. Self-service ad platforms compete for the confident buyer who believes the tools can replace an agency.
The specialist alternative
Often cheaper and deeper in one channel, but the client must coordinate the handoffs between traffic, page, creative and follow-up.
The King Kong argument
Give one operator more of the funnel, align the channels to commercial metrics, and make the offer carry some performance risk.
Its answer to commoditisation is packaging. Competitors have access to the same Google and Meta auctions. They can hire from similar talent pools and buy comparable analytics tools. King Kong wraps those inputs in direct-response creative, cross-channel ownership, case-study proof, education and a loud risk reversal. A rival can copy “SEO plus paid social” overnight. Copying the confidence and operational controls behind a guarantee is harder.
The market position is also moving upward. In March 2026, ING Australia appointed King Kong to review and rebuild its end-to-end digital acquisition funnel. The brief spans SEO, generative-engine optimisation and paid media on Google and Meta. Banking customers do not proceed neatly from ad to application; they compare rates, ask questions, open tabs and return later. Treating that behavior as one system is precisely the agency’s thesis, now applied inside a regulated enterprise.
“People do not move neatly from awareness to consideration to action. They compare, loop, ask questions, open multiple tabs and make decisions in moments.”Sabri Suby, on the ING Australia brief
05 / The people
A performance culture, for better and for pressure
King Kong’s public culture sounds like its client offer brought indoors: ambitious targets, frequent training, visible scoreboards and rewards for outcomes. Suby has described a meritocratic approach that values quality of output over hours at a desk. When company-wide goals were reached, the full team shared travel rewards, including trips to Bali and Thailand. In 2024, King Kong placed third in the media and marketing category of the AFR BOSS Best Places to Work list.
The recruiting language is deliberately muscular. The careers page seeks an “Avengers crew” of marketers, creatives, developers and salespeople and calls the team “the herd.” Behind the jokes is a serious requirement: specialists in paid search, paid social, SEO, CRO, web development, data and account strategy must collaborate around the same client economics. That can create clarity and learning. It can also make the environment demanding, because a culture built on measurement rarely offers many places to hide.
What makes King Kong interesting is not that it discovered funnels or invented performance advertising. It is that the company turned accountability itself into a consumer-facing brand. The yellow buttons, blunt headlines, reported revenue totals and guarantee all compress a complex service into one legible idea: money spent on marketing should be able to defend itself. The agency’s job, in this telling, is to replace a pile of disconnected campaign reports with a commercial narrative an owner can understand. For someone staring at a dashboard full of impressions and no obvious sales, that argument remains hard to scroll past.
