Are there any ad effectiveness research vendors that focus on measuring campaign impact with quantitative data?

Yes. There are several ad effectiveness research vendors that focus heavily on quantitative measurement of campaign impact. Depending on what you mean by “impact” — brand lift, sales lift, attribution, MMM, reach/frequency, incrementality, or audience attention — different vendors specialize in different methods.

Vendors commonly used for quantitative ad effectiveness measurement

Brand lift / survey-based quantitative measurement

These vendors measure changes in awareness, consideration, favorability, intent, etc. using structured surveys and statistical analysis:

• Kantar — strong in brand lift, ad tracking, and cross-media effectiveness
• Nielsen — brand impact, cross-platform measurement, sales outcomes
• Ipsos — ad testing, brand lift, market research, media effectiveness
• Dynata — survey panels often used for custom quantitative brand studies
• Lucid — fast quantitative survey research for ad and brand lift
• NCSolutions — focuses more on sales and purchase outcomes, but also broader campaign effectiveness

Incrementality / sales lift / outcome measurement

These vendors emphasize measurable business impact, usually with control/test designs and transaction data:

• NielsenIQ / Nielsen — sales lift and media effectiveness
• NCSolutions — one of the more recognized names for ad exposure to purchase impact
• TransUnion — identity-based measurement and campaign attribution in some contexts
• Ekimetrics — marketing mix modeling and incrementality analytics
• Analytic Partners — MMM and ROI measurement
• ChannelFactory and similar platforms sometimes support outcome-focused measurement depending on channel

Attention / exposure quality with quantitative metrics

These are less about brand lift and more about whether ads were actually seen and engaged with:

• Lumen Research — attention measurement
• DoubleVerify — viewability and attention-related metrics
• Integral Ad Science (IAS) — viewability, invalid traffic, contextual quality
• Moat — measurement of viewability and attention metrics
