TLDR
George Photios and George Pappas, the founders of digital performance agency G Squared, have launched Mercantile Co, a Chippendale-based holding group for four specialist digital agencies. The launch lands as M&C Saatchi Australia has closed, leaving mid-market brands hunting for independent partners with genuine depth.
KEY TAKEAWAYS
Who launched it and what it is
George Photios and George Pappas, the founders of digital performance agency G Squared, launched Mercantile Co on 21 September 2026 from offices at 151 Regent Street, Chippendale, in inner-west Sydney.[1] The group brings four specialist digital agencies under one structure, built on the premise that digital work should deliver measurable business impact rather than broad coverage.
M&C Saatchi Australia closed in 2025, leaving mid-market brands without an established network partner. Boutique specialists have been picking up accounts that holding-company agencies dropped as global parents cut costs, and Mercantile Co is positioning itself squarely in that current.
The four agencies and what each does
G Squared is a digital performance agency covering paid media, search engine optimisation (SEO), performance creative and web development.[2] G Squared is the founding business and the longest-standing entity in the group.
GammaDX is an artificial intelligence (AI)-native digital experience agency that builds scalable platforms and commerce solutions.[3] GammaDX targets brands that need a platform rebuilt rather than just a campaign run, sitting at the intersection of AI-driven design and commercial performance.
Wordie designs, builds and supports custom WordPress solutions, with a said ability to deliver finished websites in days rather than weeks.[4] Wordie targets organisations that need production speed without surrendering a custom build.
Burrow provides round-the-clock social media monitoring, community management and crisis monitoring through an Australian-based command centre that operates every hour of every day.[5] Most social monitoring is either outsourced offshore or handled by account teams during business hours, which makes Burrow's always-on, Australian-staffed model the most operationally distinct proposition in the group.
The model and what the founders said
The federation model keeps each agency distinct. A client of G Squared stays a client of G Squared; Mercantile Co does not absorb brands into a single unified offering. When a brief is wide enough to require more than one discipline, the relevant agencies combine, but each keeps its own team, its own identity and its own way of working.
Photios said clients need deep expertise and partners who understand how their particular discipline can drive their businesses forward, rather than agencies trying to be everything to everyone.[6]
Pappas said that when a client has a broader challenge, Mercantile Co can bring the right agencies together to combine their capabilities and solve the problem without compromising what makes each agency distinctive, giving clients both deep specialist expertise and access to a broader set of capabilities when needed.[6]
Mercantile Co is headquartered at 151 Regent Street, Chippendale, New South Wales 2008.[1]
