Already in 2025, B2B influencer marketing has solidified itself as a pivotal channel for enhancing brand credibility and driving revenue growth. Nearly half of marketers reported "outstanding results" from their B2B influencer campaigns, according to a 2025 survey by TopRank Marketing agency.
This data should not surprise us.
Trust is a cornerstone of the purchasing process. Nielsen reported that 92% of buyers trust recommendations from peers more than other forms of advertising and promotion. In B2B sectors, the role of trust is amplified with financial investments that can be high and the cost of getting it wrong is even higher.
Micro-influencers are delivering outsized value. Brands are increasingly collaborating with micro-influencers with smaller, yet highly engaged audiences. The combination of lower costs and higher engagement rates is leading to authentic and valuable brand opportunities.
Top-tier influencers are embracing video. Influencers are leveraging webinars, live streams, and short-form videos to convey complex information succinctly, catering to the preference for visual and engaging content on LinkedIn.
Brands are making data-driven investments. The ability to track and measure the impact of influencer collaborations is becoming a standard rather than a luxury. Sophisticated social media monitoring platforms and campaign platforms, like Endorsa, make it easy to track lead generation, conversion rates, and overall ROI.
