Their median headcount is 229. Half of them were founded in 2009 or later. The most common headquarters are Melbourne (12), South Melbourne (3) and Southbank (3).

These Victorian companies are predominantly large to mid-sized firms operating in marketing, advertising, and entertainment services. Many specialize in digital solutions and brand experiences, serving a broad range of clients. Several companies, such as SEO, Sensis, and DT, are significant players in the advertising services sector, while PMY Group focuses on technology infrastructure for events.

## 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.
