Yes, there are systems that help match the right influencers to your brand. This process, known as Influencer Discovery, is one of the core functions of influencer marketing platforms. These platforms use audience analytics to identify influencers who have a persona or style that aligns with your brand image.

When considering a platform, key features to look for include:
1. Comprehensive Database: The system should have an extensive database of influencers across multiple social media platforms, thus offering a range of options.
2. Advanced Search Filters: The ability to segment and filter influencers based on specific criteria like demographics, interests, engagement rate, etc, will help narrow down your search.
3. Audience Analytics: Detailed insights into an influencers’ audience can reveal if their followers match your target market.

For example, Flinque is a platform that offers these features. It not only provides influencer discovery but also guides through campaign planning, performance tracking, and ROI measurement. However, it is important to note that there are other platforms available too. The choice of platform depends on your specific needs, resources, and marketing strategy.

In addition, some platforms also use AI algorithms to suggest influencers whose personas align with your brand, thus making the search process even more refined. Again, not all platforms provide this feature, so referencing your goals in your selection process is crucial.

Remember, influencer discovery is just one step in influencer marketing. A well-thought-out campaign, performance tracking, and ROI measurement are equally important for the success of your marketing efforts.

So, when considering an influencer marketing platform, it’s essential to have an understanding of your overall strategy and where influencer discovery fits into it.
