Sigma’s New Scope: From Signal Sorting to End-to-End Control
MiQ’s Sigma platform is an AI advertising platform that unifies planning, campaign activation software, and marketing measurement tools in a single workflow so marketers can convert fragmented consumer signals into coordinated media decisions and measurable outcomes across channels. Built to respond to audiences moving between video, social, commerce, and AI chat environments, Sigma now moves beyond optimisation to cover the full campaign lifecycle. According to MiQ, Sigma has powered more than 40,000 campaigns for over 2,300 advertisers since launch, showing how quickly the system has become central to their programmatic operations. Internal testing reports that Sigma campaigns deliver a return of $2.22 for every $1 spent compared with standard programmatic setups, driven by incremental reach, higher conversions, and better cost per acquisition. The latest update adds planning and measurement features to an already active system, turning separate point solutions into one interface.
AI-Powered Planning: Browsing Intelligence and Audience Curation
The expanded Sigma release focuses first on planning, where marketers often juggle several disconnected tools. Sigma now lets teams curate audiences and personas, then build omnichannel plans within the same environment they use to activate. The new Browsing Intelligence feature is central to this shift. It examines behavioural, contextual, attention, and AI-related browsing trends to reveal how consumers compare options in mid-funnel moments. With these insights, planners can align creative, frequency, and channel mix with the consideration phase instead of relying on broad demographic assumptions. MiQ frames this as a response to “fragmentation”, with Fiona Roberts noting that when “data, decisioning and activation come together in one system”, clients can plan faster and reinvest with more confidence. For brands under pressure to move from static media plans to live, signal-based strategies, Sigma’s AI-driven planning environment is designed to make that transition practical.
Activation Deepens Across Key Media Environments
While Sigma began as a decisioning engine, MiQ has steadily expanded its campaign activation software layer so that plans built in the platform can be executed without handoffs. Sigma now turns insights and audience definitions into live buying activity across 16 open web and walled garden environments, including Google and YouTube. This means traders can respond to changing signals by doubling down on high-performing segments or shifting budgets mid-flight, without exporting data into another system. MiQ says its traders are now making twice as many optimisations with Sigma as before, and that speed links directly to performance gains. Activation is also enriched by a growing data spine of more than 600 feeds and 2.5 petabytes of information from providers such as Circana, TitanOS, and Evertune, plus AI architecture integrations with Databricks that help keep decisions current as incoming signals shift.
Total Measurement: Connecting Channels and Closing the Loop
On the measurement side, MiQ has introduced Sigma Total Measurement to bring outcome analysis into the same interface as planning and activation. Rather than judging success by channel-specific KPIs alone, Sigma Total Measurement is built to show how different placements and formats work together across the consumer journey. Marketers can see where investment compounds, identify weak links in the funnel, and reallocate spend accordingly. This changes measurement from a post-campaign reporting task into an always-on feedback loop that informs future planning cycles. The intent is to move brands away from optimisation against short-term media metrics toward long-term sales growth and incremental reach. By using the same AI backbone to interpret performance signals that it uses for planning, Sigma aims to reduce the lag between insight and action, tying marketing measurement tools directly to the next activation decision.
Why a Unified Workflow Matters for Marketers
MiQ positions Sigma as an answer to tool sprawl in digital advertising, where separate systems for planning, activation, and reporting lead to slow decisions and lost insight. Consumers now generate thousands of digital interactions per day, which means marketers need platforms that can interpret signals continuously rather than in scheduled reporting cycles. Sigma’s unified environment is designed so that audience discovery, budget planning, flighting, optimisation, and measurement share the same data spine, cutting down on manual exports and reconciliation. Partnerships with data and measurement providers, plus MiQ’s 16 years of trading data, feed this loop. For marketing teams, the practical outcome is more control: fewer interfaces to learn, clearer links between media choices and business results, and the ability to adapt campaigns in near real time as Sigma’s AI systems identify patterns in how people watch, browse, and buy.
