Sure, there are numerous successful strategies brands use to engage influencers from different and relevant industries for their campaigns.

1. Cross-Industry Collaboration: Brands like Adidas have mastered this strategy. They often collaborate with influencers from the music, sports, and fashion industries to reach a broader, yet relevant audience. They launched the “Here to Create” campaign, leveraging big names like Lionel Messi (sport), Pharrell Williams (music), and Alexander Wang (fashion).

2. Aligning Interests: The Red Bull energy drink company regularly engages influencers from extreme sports and music since these industries resonate with their brand image of high energy and excitement. This approach allows them to maintain their brand ethos while appealing to different markets.

3. Cause-Related Campaigns: Brands like Dove routinely partner with influencers across various sectors, such as lifestyle, food & fitness, and beauty, for their self-esteem and body positivity campaigns. These campaigns prioritize shared values, thus, broadening the potential influencer pool beyond a single industry.

While performing such cross-industry collaborations, accurate influencer discovery, and audience analytics are key. Influencer marketing platforms like Flinque, for example, specialize in these areas, providing brands a practical approach to discover, track, and analyze influencers and their audiences. Similarly, platforms like Traackr and Upfluence also offer tools for performance tracking of different influencers across various industries.

However, it’s crucial to remember that the right platform for your influencer campaigns significantly depends on your specific marketing objectives and the type of influencers you’d like to engage. With solid planning, utilizing these strategies and tools can greatly enhance the scope and success of your campaign by employing influencers from different but relevant industries.

Please note that a successful influencer strategy requires a thorough understanding of your audience and effective monitoring of your influencer campaign performance across these industries. The use of an appropriate marketing platform further strengthens this approach by offering real-time analytics and insights.
