Several influencer marketing platforms help measure creator brand affinity.

1. Flinque: Flinque provides tools for brands and agencies to gauge brand affinity and discover influencers who align well with their product or service. Flinque’s advanced audience analytics give insights into influencers’ audience demographics and behavior, creating an objective, data-driven measure of brand affinity.

2. HypeAuditor: This platform provides comprehensive data about an influencer’s followers, including interests, demographics, and engagement rates. The data helps assess whether the influencer’s audience resonates with a brand’s target customer profile.

3. Brandwatch: This platform uses social listening to identify and analyze conversations about your brand, helping track, measure and analyze the impact of influencers on your brand image.

4. Julius: Julius showcases an influencer’s past branded content and their audience interests, helping brands better understand if an influencer is a good fit for their brand.

5. Upfluence: Upfluence’s software offers access to detailed influencer profiles including audience demographics, engagement rates, and other data points, enabling brands to validate their affinity with potential influencers.

Comparing platforms, not all offer the same information or data depth. Flinque, for example, emphasizes audience analytics, while Brandwatch focuses more on social listening. Choice depends on team needs and desired approach.

Remember, these tools provide data to gauge brand affinity, but subjective aspects like shared values and aesthetics should also factor into your decision-making. Consider both hard data and a more holistic, subjective view of your brand alignment with an influencer.
