The Largest Australian Startups and Unicorns in 2026

Australia has produced some of the world's most successful technology companies relative to its population. Atlassian, founded in Sydney, became a global software giant, and a new generation of Australian-founded companies, led by Canva, has followed. Many Australian startups sell to customers worldwide from early on, because the home market is small, and several have moved headquarters abroad while keeping large teams at home. This guide ranks the Australian-founded private companies in our database by sourced valuation, explains how they grew, and covers the strengths and challenges of the Australian startup ecosystem.

Every company in the table links to a full profile with its sourced valuation, funding history and investors. We include private companies founded in Australia, even if they now list their headquarters elsewhere; the country column shows the current headquarters we record. Public companies such as Atlassian, Afterpay (acquired by Block) and Xero (founded in New Zealand) are discussed for context.

The ranking

Canva: Australia's most valuable startup

Canva, founded in Sydney in 2013, is the most valuable private Australian company. It was valued at about US$42 billion (reported as A$65 billion) in a 2025 employee share sale, and in August 2026 its main Australian backers marked their stakes down to about US$34.9 billion, citing a lower revenue growth outlook tied to AI costs. Its online design platform, used by hundreds of millions of people, made graphic design accessible to non-designers and has expanded into documents, presentations, video and workplace tools, along with AI features. Canva's founders, Melanie Perkins, Cliff Obrecht and Cameron Adams, built it into one of the world's most valuable private software companies, and it has long been seen as a potential IPO candidate.

Fintech: Airwallex

Airwallex was founded in Melbourne and now lists Singapore as its headquarters. It provides cross-border payments, multi-currency accounts and financial infrastructure for businesses, and was valued at US$11 billion after a June 2026 funding round. Its move reflects a common pattern: Australian fintechs often relocate to larger financial centres as they expand internationally, while keeping significant engineering in Australia. Afterpay, the Australian BNPL pioneer acquired by Block in 2022, is another example of Australian fintech reaching global scale.

Marketing and e-commerce technology: Rokt

Rokt, founded in Sydney, offers e-commerce marketing technology that shows relevant offers to customers during checkout, used by large retailers, ticketing companies and travel businesses. It was valued at US$3.5 billion and now lists New York as its headquarters, reflecting the importance of the US market to its business.

HR and people software: Culture Amp and Employment Hero

Two Australian companies have become leaders in HR technology. Culture Amp, based in Melbourne, provides employee engagement surveys and performance management to thousands of organisations worldwide and was valued at about US$1.5 billion in 2021. Employment Hero, based in Sydney, provides HR, payroll and employee benefits software for small and medium-sized businesses and was valued at just under A$2 billion. Both show how Australian software companies can win global customers in business software.

Creator tools: Linktree

Linktree, founded in Melbourne in 2016, created the popular "link in bio" page used by tens of millions of creators and businesses. It raised US$110 million at US$1.3 billion in March 2022, led by Index Ventures and Coatue. Its story shows how a simple product can spread worldwide through viral adoption.

Healthcare AI: Harrison.ai

Harrison.ai, based in Sydney, builds AI for radiology and pathology, helping clinicians read medical images more efficiently. It was valued at about AU$789 million, below unicorn status, but is one of Australia's most prominent AI companies and has expanded into international markets.

Why Australian startups go global early

With a population of about 27 million, Australia's domestic market is limited for most technology products. Founders who want to build large companies must sell internationally, often to the US and Europe, from early on. This has produced companies with global ambitions and products designed for international use. Time zone differences and distance from major markets are challenges, which is why many companies open US offices or move headquarters. Strong English-language markets, a skilled workforce and a stable economy are advantages.

Funding the ecosystem

Australian venture capital has grown significantly since the mid-2010s, with firms such as Blackbird Ventures, AirTree Ventures, Square Peg Capital and Main Sequence investing in local startups. Superannuation funds, Australia's large pension system, have also invested in venture capital and growth companies. Large later-stage rounds often include international investors such as Sequoia, Index Ventures and Coatue. Government programmes, including research and development tax incentives, support early-stage companies.

Challenges

• Market size: companies must expand abroad to grow large.
• Talent competition: experienced executives and engineers are in demand, and some move overseas.
• Capital for late stages: very large rounds usually require overseas investors.
• Listings: some companies choose US listings or acquisitions over the Australian Securities Exchange.

Where Australian startups are strongest

Australia has particular strengths in software for businesses, fintech, design and creative tools, health technology, mining and resources technology, and climate and energy innovation. Universities in Sydney, Melbourne, Brisbane and Adelaide contribute research and talent, and quantum computing and space technology have become growing areas.

How to research an Australian startup

For private Australian companies, useful sources include company announcements, filings with the Australian Securities and Investments Commission (ASIC), which publish some financial information for larger companies, and reporting from local outlets such as the Australian Financial Review. Our guide to researching private companies explains general methods.

Key takeaways

Canva leads Australian startups by a wide margin, followed by Airwallex and Rokt, with Culture Amp, Employment Hero and Linktree among other unicorns. Australian founders build global companies from early on, often moving headquarters abroad while keeping teams at home. The ecosystem has grown rapidly but still relies on international capital for the largest rounds.

A short history of Australian tech success

For decades, Australia's largest companies were banks, miners and retailers, and technology entrepreneurs often moved to Silicon Valley to build their businesses. That began to change in the 2000s and 2010s. Atlassian, founded in Sydney in 2002 by Mike Cannon-Brookes and Scott Farquhar, grew without venture capital for years and listed on the Nasdaq in 2015, showing that a global software company could be built from Australia. Its success inspired a generation of founders and created wealthy alumni who became angel investors. Afterpay, founded in Sydney in 2014, became a global leader in buy now, pay later and was acquired by Block in 2022 in one of Australia's largest technology deals. Canva, founded in 2013, went on to become one of the most valuable private software companies in the world.

These companies changed how investors viewed the country. International venture capital firms began investing directly in Australian startups, and local funds raised much larger pools of capital. Employees who received shares in successful companies started their own businesses or invested in others, a pattern seen in every major startup ecosystem. Today, Sydney and Melbourne each have active startup communities, and Brisbane, Perth and Adelaide are growing.

Australian founders often say that building for the world from day one is both a challenge and an advantage. It forces them to think about international customers early, to design products that work across countries and to build remote collaboration habits, which became even more valuable after the pandemic made distributed teams common. Companies such as Canva, Culture Amp and Employment Hero have used these strengths to win customers far beyond Australia.

Sectors to watch next

Beyond software and fintech, Australia has growing strengths in climate and energy technology, given its abundant solar, wind and critical minerals; in quantum computing, with several university spinouts; in space technology; and in health and medical technology. Artificial intelligence is attracting more investment, though Australian AI companies are still smaller than those in the US and UK. Government support for critical minerals processing and clean energy could create new large companies in coming years.
