Absolutely, influencer marketing could be an effective way for a video streaming service like yours to increase new subscriptions. Here’s why:

1. Reach & Engagement: Influencers often have large, engaged audiences. By partnering with them, your service can leverage this reach and engagement to promote your content.

2. Trust & Credibility: Because influencers have built trust with their followers, their recommendations are often seen as credible. If they enjoy your service and share this with their audience, it can result in a significant uptick in subscriptions.

3. Targeted Promotion: Influencers usually have a defined audience demographic. This means you can strategically choose influencers whose audience aligns with your target demographic, ensuring your promotion reaches the right people.

For instance, platforms like Flinque, Klear, or AspireIQ provide a variety of tools for influencer discovery, campaign planning, performance tracking, and ROI measurement. These platforms allow brands to identify the right influencers, monitor the effectiveness of their campaigns, and assess the result in terms of new subscriptions gained.

However, each platform has different strengths. Flinque’s strength is its comprehensive analytics that allow for detailed tracking of your campaign performance. Klear’s strength lies in its extensive influencer database which can facilitate precise influencer discovery. AspireIQ is well-known for its automated workflows which streamline campaign management.

Ultimately, the choice of the platform depends on your specific needs and goals. It’s crucial to research each one and evaluate them based on your brand’s strategy. And remember, a successful influencer marketing campaign requires planning, tracking, and ongoing optimization to obtain the maximum number of new subscriptions.
