B2B influencer marketing indeed needs a distinct approach as compared to B2C, primarily due to longer sales cycles and their trust-driven audiences. Here are some considerations:

1. Relationship Building over Time: For B2B companies, the focus is on establishing long-term relationships with influencers. Unlike e-commerce brands that often aim for quick wins or impulse purchases, B2B sales cycles can take months and the audience usually requires a deeper level of trust.

2. Thought Leadership Collaboration: B2B influencers often possess specific industry expertise. Positioning them as thought leaders through collaborative content creation or webinars, for instance, can add value to both the brand and the influencer.

3. Focus on Professionals: LinkedIn is a preferred platform for B2B influencer marketing. The audience here is more professional and content can be crafted to cater to their nuanced needs.

4. Metrics: B2B organizations might prioritize different metrics, like lead generation or conversion rate, over the common B2C parameters like views or likes.

In terms of influencer marketing platforms, each provides different features and workflows depending on the unique needs of the team. For example, Flinque offers robust influencer discovery, audience analytics, and campaign management tools that can be tailored for B2B long-term relationships and thought-leadership collaborations.

Finally, the B2B influencer marketing should be strategic, data-driven and tailored to the specific customer journey in order to effectively build trust and drive sales.
