3Q/DEPT

Paid media for brands that want to grow past isolated campaigns is the core of 3Q/DEPT's work. The agency sits inside DEPT, a group that presents itself as a growth invention company working where technology and marketing meet, and it handles the digital media side of that mix.

Why it rejects siloed performance marketing

The agency argues that much performance marketing is run as separate tactics, each judged only on ad spend and return, which makes it hard to plan the next stage of growth. Its alternative, which it calls growth marketing, puts strategy, data and testing into every channel. At the center is a proprietary growth model that relies on predictive and automated intelligence, and the agency says its guiding principle is to accept no limits on how far a brand can go.

Media buying, connected TV and measurement

Its day-to-day services are full-scale digital media management, advertising on connected TV and over-the-top streaming services, and data science and analytics. The analytics side is described as broad strategic analysis meant to show which activity is moving results and where the budget should go next.

The values it says it works by

Three commitments are repeated in its own material: challenging the status quo to find growth, acting for the greater good by supporting colleagues, clients and communities, and holding itself accountable to its teams, its markets and its clients. It also says client relationships rest on honesty, transparency and collaboration, and that it hires and promotes with a deliberate mix of backgrounds in mind.

What the parent group says about itself now

The current DEPT site describes a group split evenly between technology and marketing, with more than fifteen years behind it. It lists the Webby Agency of the Year title for three years running, from 2022 to 2024, a Campaign award for digital innovation in 2023, a place among Forrester's top commerce services providers, and a Leader rating in a 2026 Gartner report on global digital marketing agencies.

The group's offer has widened beyond media. It now promotes AI transformation consulting, work on the future of the customer journey, and a platform called Deptify that connects tools, data and workflows so briefing, strategy, content, media and measurement sit in one layer. The sectors it names include banking, financial services and insurance, technology, media and telecoms, and retail and commerce, with 3Q/DEPT's own focus remaining fast-growing and enterprise brands that buy media at scale.
