Blis adds Polk automotive data to ad platform

Blis said Tuesday it has integrated Mobility Global’s Polk Audience Data into its platform, giving advertisers verified automotive intelligence tied to vehicle ownership and in-market timing. The move is designed to help brands build audiences from confirmed consumer behavior instead of inferred signals.

Why it matters: - Advertisers using Blis can now target audiences with source-level automotive data tied to ownership, loyalty and purchase behavior. - The integration is meant to reduce reliance on probabilistic assumptions and improve precision for automotive campaigns. - Blis says the addition strengthens its ability to connect consumer mobility, shopping and media behavior into durable audience signals.

What happened: - Blis, T-Mobile's omnichannel advertising platform, announced a partnership with Mobility Global on Aug. 12, 2026. - The partnership gives Blis access to Polk Audience Data through a direct integration. - The announcement was made in New York. - Blis said the integration brings automotive intelligence around ownership and in-market timing into its platform.

The details: - The platform can now build audiences based on confirmed vehicle ownership, make, model and engine type. - Marketers can also target broader automotive intent categories, including servicing, aftermarket behaviors, and wheels and tires. - Blis says it uses more than 500 attributes related to ownership, loyalty and purchase behaviors. - Polk automotive data can be combined with carrier insights and third-party purchase signals. - The combined signals are designed to help brands identify and reach more relevant audiences. - The audience sets can include consumers researching vehicle purchases through apps such as CarGurus, AutoTrader, Carvana and Kelley Blue Book. - The platform can also reach current owners and brand considerers using OEM apps such as FordPass, BMW Connected and Hyundai Bluelink. - Verified EV owners and high-intent electric vehicle audiences can be identified through charging apps including ChargePoint, EVgo and Electrify America. - Blis says the integration expands intelligence available in the platform across automotive ownership, behavioral, mobility and purchase signals. - The company’s website is more information. - Mobility Global’s website is more information.

Between the lines: - The deal reflects a broader push in ad tech to move from inferred audience models to verified data tied to real-world consumer activity. - For automotive marketers, the value is less about broader reach and more about tighter audience definition around purchase intent and vehicle lifecycle stage. - Blis is positioning carrier data plus Polk data as a differentiated signal stack for media effectiveness.

What's next: - Blis is expected to use the Polk integration to broaden automotive audience activation across its omnichannel platform. - Brands and media agencies may use the new data set to refine targeting around ownership, shopping and EV interest. - The companies did not announce pricing, rollout timing or customer names in the release.

The bottom line: - Blis is betting that verified automotive data, paired with mobility and carrier signals, will give advertisers a more accurate way to reach car buyers and owners.
