Seeking Recommendations for Reliable Data Providers for CPG Brand Campaigns

I am currently working on a project aimed at identifying and testing data partners over the coming quarters for a major CPG brand. I'm interested in hearing about any positive experiences you've had with specific data providers. We are open to various types of data, not just the typical 'in-market' or 'enthusiasts' categories that CPG brands frequently utilize. Additionally, I'm keen on finding out if any of these partners have robust audience modeling capabilities that can integrate first-party data and expand it intelligently within their datasets. Our initial activations will mainly be through TTD, but we may also explore other DSPs in the future. I appreciate you taking the time to share your insights and recommendations!
