3. NinjaOutreach: This platform can be very effective for smaller or niche campaigns. It’s robust but offers a more personalized feel, and it’s equipped with a solid search engine for influencer discovery and exhaustive audience analytics.

4. Klear: Known for its detailed influencer profiles and demographic details. It helps you understand the audience you’re targeting which can greatly improve your campaign efficiency.

5. Tribe: An excellent platform for those wanting to execute content-led campaigns. With Tribe, brands can set a brief and micro-influencers submit their content ideas. It is a unique approach offering creative and cost-effective solutions.

6. InflueNex: A dedicated YouTube influencer platform with useful features like a scoring system for influencers, and an advanced search filter.
