Best Influencer Marketing Platforms for B2B and LinkedIn Creators

Managed B2B influencer marketing service connecting brands with 800,000+ vetted LinkedIn professionals.

Editor's takeBrandRefer curates an invite-only network of LinkedIn professionals in roles like IT, engineering, and sales, a deliberate contrast to generic celebrity-focused influencer platforms. Case studies document cost-per-lead figures between $25 and $35, with lead generation campaigns converting at 10 to 20 percent. The tradeoff is transparency, since there is no public pricing and few independent software reviews to verify results outside vendor-supplied case studies.

Creator analytics platform with an Authenticity Score, a Spotlight media kit, and data on 10 million+ creators.

Editor's takeFavikon builds its Authenticity Score from 5 criteria, including engagement quality and the share of AI-generated content, to separate real influence from inflated numbers. Its Spotlight feature turns that data into a shareable media kit, which creators describe as a social media resume for brand deals. Pricing starts as low as $69 a year for creators, though Business plans can reach around $299 a month.

Influencer and affiliate platform with Live Capture finding influencers in your own customer list.

Editor's takeUpfluence's Live Capture scans a brand's own customer list to find people who are already buying and posting, and its own data shows those creators are 7x more likely to say yes to a partnership. It is the only influencer platform natively integrated with Amazon for attribution, alongside Shopify and WooCommerce. Pricing is not published and reportedly starts around $2,000 monthly, locked into a mandatory 12-month contract that Trustpilot reviewers say is difficult to exit early.

Influencer marketplace with escrow-protected payments and transparent, upfront creator pricing.

Editor's takeCollabstr works like a marketplace rather than a full campaign tool: brands browse influencer rates upfront, and payment sits in escrow until they approve the finished content, with unanswered orders auto-refunded after 72 hours. More than 310,000 brands, including Wealthsimple and Hopper, have used it, and it holds a 4.2 Trustpilot rating. Despite Collabstr's stated identity and follower audits, Reddit users report still running into influencers with fake followers, so vetting the numbers yourself remains worthwhile.

Influencer marketing suite with a 170M+ profile database, AI fraud detection, and publicly listed pricing.

Editor's takeInfluencity stands out for publishing its prices, four tiers from $168 to $698 a month, in a market full of quote-only vendors. Its 170 million profile database and Follower Quality AI help filter out fake engagement. Communication still runs through email rather than in-platform messaging, unlike some rivals.

Search-first influencer platform with a 350M+ profile database, fake follower detection, and deep Shopify affiliate tools.

Editor's takeModash ranks 6th of 7 in this category at 8.7. Its database size and fraud detection outclass rivals for data accuracy. Missing platform coverage beyond the big three is the clearest gap.
