This selection of Australian online marketplaces includes a mix of large, established corporations and younger technology firms. Companies like Greencap, founded in 1914, operate across diverse sectors including home improvement and industrials, while Winning Group, founded in 1906, specializes in retail and logistics. Younger firms such as Canva, a visual communications platform, and Freelancer.com, connecting users with projects, represent the technology sector.
A notable pattern is the strong presence of companies focused on connecting individuals or businesses with services, such as Mable in disability and aged care support, and UHG in healthcare. Many of these companies, including SEEK for employment and CAR Group for vehicles, are headquartered in major cities like Sydney and Melbourne, with a concentration in technology and internet services.

Turn this list into pipeline
Tamtam finds the decision-makers at every company on a list like this one, with verified emails, phone numbers and the buying signals that tell you when to reach out.
How this list is built
Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 12, 2026.
