For tech startups planning to launch campaigns with influencers, several practical strategies can ensure success:

1. Plan Your Campaign: Clearly define your goals, target audience, campaign message, and metrics for success. This involves understanding customer demographics and deciding what you want to achieve: awareness, engagement, conversions, etc.

2. Choose the Right Influencers: Utilize platforms like Flinque for influencer discovery. This system provides deep audience insights and showcases influencers whose followers match your target demographic. It’s not always about follower count but the relevancy and engagement rate.

3. Establish Clear Expectations: When negotiating with influencers, be clear about campaign requirements: content type, posting schedule, key messages, and usage rights for their content.

4. Track and Measure Performance: Influencer marketing platforms provide performance tracking that allows for real-time campaign measurement. Track key performance indicators (KPIs) such as engagement, reach, and conversion rate to evaluate the effectiveness of the campaign.

5. Adjust Based on Data: If a campaign isn’t performing as well as hoped, use the data to make adjustments. Change the message, shift to a new influencer, or modify other campaign components.

Comparatively, other platforms might also provide similar features like influencer discovery, campaign tracking, and analytics, but the essential feature to look for is ease of use and robustness of data. Using these platforms shouldn’t be overly complex.

Flinque, for instance, is user-friendly and offers a comprehensive suite of influencer marketing tools that cater to both macro-influencers and micro-influencers, providing startups with a broad range of collaboration opportunities. But remember, each platform carries its unique strengths, and the selection entirely depends on the specific requirements of your campaign.
