Sigma Redefined: From Signal Interpreter to Full AI Advertising Platform
MiQ’s Sigma is an AI advertising platform that connects data, planning, activation, and marketing measurement tools in one system so marketers can turn fragmented consumer signals into coordinated campaign decisions and clearer business outcomes across digital channels. One year after launch, Sigma has powered more than 40,000 campaigns for over 2,300 advertisers, and internal testing shows it delivers $2.22 in value for every $1 spent compared with standard programmatic setups. The latest expansion turns Sigma from a primarily activation-focused engine into a more complete campaign planning software and advertising activation platform. Sigma now lets marketers curate audiences and personas, plan media, activate across key environments, and measure results within a single workflow. This integrated design aims to reduce handoffs between teams and tools, so decisions made at the planning stage can be tested, refined, and reinvested quickly based on performance.
New Planning Capabilities: Browsing Intelligence and Audience Curation
At the planning stage, MiQ has added AI-powered Browsing Intelligence and deeper audience curation features to Sigma. Browsing Intelligence focuses on the mid-funnel, where consumers are in the consideration phase and switching between watching, browsing, and buying across thousands of daily digital interactions. Marketers can tap into omnichannel behavioural, contextual, attention, and AI trends to identify the moments that shape brand choice. These insights help planners decide which audiences to prioritise and which environments deserve budget before a campaign launches. Sigma also allows users to curate detailed personas and audiences inside the same AI advertising platform, reducing the need to move data into separate campaign planning software. MiQ’s 16 years of trading data and expanded AI architecture integrations, including Databricks, feed these planning tools so they can update in closer to real time as new consumer signals appear.
Sigma Total Measurement: Connecting Channels and Outcomes
On the measurement side, Sigma Total Measurement is designed to shift focus from short-term media metrics to the entire consumer journey. Instead of treating each channel in isolation, Sigma shows how video, social, commerce and other environments work together, so marketers can see where investment is compounding and where it stalls. According to MiQ, Sigma users can now optimise for long-term sales growth rather than isolated media KPIs, and reinvest with greater confidence. This aligns with growing demand for marketing measurement tools that connect impression-level data with business results. Sigma’s expanded data spine—now more than 600 feeds and 2.5 petabytes of information from providers such as Circana, TitanOS and Evertune—gives the platform a broader base of signals to evaluate performance. By embedding these metrics directly inside the advertising activation platform, MiQ aims to shorten the loop between insight and budget reallocation.
Activation at Scale: Turning Insights into Campaign Decisions
Sigma’s activation capabilities translate planning and measurement insights into live campaign changes across 16 open web and walled garden environments, including Google and YouTube. MiQ says that bringing data and decisioning together in a single AI system has doubled the number of optimisations traders can make, which in turn has improved campaign performance. Partnerships with providers like Evertune underline the activation focus: when AI search visibility data is combined in real time with what consumers are watching and buying, then linked straight to planning and activation, it becomes a driver of media decisions rather than static research. Sigma’s advertising activation platform aims to maintain this feedback loop continuously, interpreting signals and adjusting bids, budgets, and creatives as behaviour shifts. The upcoming Planning Agent, already launched in the United States, is expected to extend this automation further as it rolls out more widely.
Strategic Impact: A Unified Workflow for AI-Driven Marketers
By bringing planning, measurement, and activation into one AI advertising platform, Sigma aims to simplify a fragmented digital landscape where consumers can rack up more than 2,500 daily digital interactions. MiQ leaders argue that the “gap between those who can and cannot turn signals into real-time decisions is widening fast,” and Sigma is designed to close that gap by aligning data, decisioning, and activation in the same environment. Marketers gain an integrated set of marketing measurement tools and campaign planning software that feeds directly into an advertising activation platform. This reduces dependence on disconnected point solutions and manual file transfers, while giving teams a consistent view of audiences, channels, and outcomes. With Sigma live across MiQ’s operating regions and new capabilities rolling out through 2026, the platform is positioned as a comprehensive option for brands seeking AI-driven advertising management that spans the full campaign lifecycle.
