The 15 Best B2B Influencer Marketing Agencies in 2026

The best B2B influencer marketing agency for most B2B tech teams is one that can show who engaged, not just how many saw the post. This list covers 15 options, starting with Fame Influencer. It is our own list and Fame is our company, so read it with that in mind. We checked each competitor's own website on 3 November 2026 and only state what those sites say. Where a site says nothing, we write "not published" or "not stated", which means only that we could not find it publicly.

How we chose and ordered this list

Each agency had to offer influencer or creator work that it presents as suitable for B2B brands. The order runs from the most LinkedIn and B2B-specific offer to the most general. It is not a quality score, because public websites cannot tell you which agency produces the best results. We did not speak to the agencies' clients, and we did not test their services.

We left out two names that often appear on similar lists. Refine Labs' pricing page covers paid media and creative, with no mention of influencer or creator work. inBeat presents its strategies as adaptable across B2B and B2C, and we kept the list to agencies with a more explicit B2B or LinkedIn offer.

The 15 best B2B influencer marketing agencies

1. Fame Influencer

Fame Influencer places sponsored posts on vetted LinkedIn creators' own profiles, for B2B tech and SaaS companies. Creators come from practitioners on the 300+ B2B shows Fame has produced, and they are vetted for engagement pods and comment farms.

• Pricing: all published on our Fame Influencer pricing page. A two-month test is $9,500 for five placements on five creators ($1,900 each, paid on signing). The subscription is $21,000 a quarter for 10 placements ($2,100 each, billed quarterly in advance, one-quarter minimum). A five-placement pack is $10,000 ($2,000 each). Creator fees are included in all of them.
• Reporting: named engagers by company and role, ICP-engagement percentage, blended CPM against LinkedIn Ads benchmarks, and a placement counter. Subscription reports are monthly.
• Process: a shortlist within two weeks of a 30-minute discovery call, with a brief and client approval on every placement. If a placement under-delivers, it is replaced.
• Evidence to weigh: our published sponsored post examples are posts on founder Tom Hunt's own profile (220,000 followers), not results from the creator roster. The roster has no campaign results to publish yet, so ask us about that directly.
• Not right for: companies outside B2B tech and SaaS, anyone wanting TikTok or Instagram alongside LinkedIn, teams with a total budget under $9,500, and buyers who need an agency with published multi-creator results today. Thought Leader Ads start from phase two, so they are not part of the test.

2. Creator Authority

Creator Authority says it is built for LinkedIn and professional audiences, and describes itself as a certified LinkedIn Marketing Partner. It covers strategy, creator identification, production, paid media and reporting. Its vetting statement is among the more specific here: audience quality, industry fit and brand safety, with identification across more than 25 criteria. Its reporting page lists organic and paid performance, sentiment, and who engaged by role, industry and region.

Not right for: buyers who need a price before a first call, or who need a programme centred on channels other than LinkedIn.

3. Creator Match

Creator Match calls itself a creator marketing agency for tech brands, and says LinkedIn is its primary focus, with some other channels possible. It runs matching, relationships, negotiation, payouts and measurement. Creators must show consistent engagement and a loyal following, and there is no minimum follower count. Reporting spans reach, engagement and conversions across creators. Pricing starts from the budget you share, with no public rates.

Not right for: non-tech brands, or teams who want to compare prices without first sharing a budget.

4. Cherry Lane

Cherry Lane is a B2B influencer agency for SaaS, tech and GTM brands, covering LinkedIn, YouTube, TikTok, Instagram, newsletters and podcasts. It recommends a $20,000 budget for a first campaign, and says exact budgets vary. It does not publish a fee structure. It says creators are handpicked for ICP fit, engagement quality and content history. KPIs include leads, impressions, engagement, click-throughs and brand lift. It names Typeform as a client, with 40+ thought leaders activated.

Not right for: teams with a budget well below its recommended starting point, or buyers who want a fixed per-placement price.

5. Kudos Narratives

Kudos Narratives runs LinkedIn B2B influencer campaigns end to end, with other social platforms on request, and also offers speaker scouting. After a trial, clients can move to a subscription that it says delivers 10+ placements a quarter. It promises a shortlist of vetted influencers, without giving the criteria, and regular progress reports with analytics. Prices are by quote.

Not right for: buyers who want published vetting criteria or report contents before they talk to anyone.

6. BrandRefer

BrandRefer connects B2B brands with LinkedIn micro-influencers, and reports a combined network of 800,000+ LinkedIn professionals across the USA and EMEA. Its model suits distributing webinars, whitepapers, ebooks and reports for lead generation or awareness. Its homepage sets a floor of 1,000+ followers and active LinkedIn use, and shows per-lead costs in case studies but no price list. Selection, quality assurance and reporting appear as steps without detail.

Not right for: brands seeking a few prominent named voices, rather than wide micro-influencer distribution.

7. OST

OST is a B2B social agency with a separate influencer service, from one-off pilots to global programmes. It says it researches, vets and hand-picks influencers from a network of 1,000+ B2B experts, handling negotiation, contracts and payment. It reports on reach, engagement, clicks, leads and conversions.

Not right for: smaller teams who only want creator placements and do not need a wider social partner, or those who need a list price.

8. TopRank Marketing

TopRank Marketing is one of the longer service lists on this page: strategy, audits, recruitment, sponsored content, co-hosted webinars and podcasts, affiliate programmes and event packages, with creators on LinkedIn, TikTok and beyond. It names clients including monday.com, Adobe and Sprinklr, and its homepage cites 2,000+ influencers in its network. It says it measures content, influencers and promotional spend, without listing specific metrics. It does not set out vetting criteria.

Not right for: teams who just want a short run of sponsored posts, without a broader influencer content programme.

9. Directive

Directive is a wider B2B performance agency whose influencer service covers practitioner content, community activation, analyst briefings, podcasts, speaking and customer advocates. It selects creators with its own Stratos Influence Score, and its LinkedIn page says partners are assessed for engagement authenticity, strategic fit and ICP relevance. It describes connecting partnerships to MQLs and revenue through CRM integration.

Not right for: buyers wanting a simple, fixed-scope LinkedIn placement package.

10. HireInfluence

HireInfluence is one of the few agencies here to name a LinkedIn figure, saying programmes start at approximately $100,000 per engagement. It evaluates audience composition by title, seniority and industry, as well as engagement quality and compliance readiness. Measurement includes reach in target accounts, brand lift, and MQL and SQL contribution where CRM integration exists.

Not right for: teams who want to test a small campaign before committing six figures.

11. Limelight

Limelight is mainly a software platform rather than an agency, included because it also sells a managed service. Its pricing page lists the platform at $599 a month with no minimum term, and the managed service from $4,000 a month, as a tiered percentage of spend with a three-month commitment. It describes creators as verified, matched by algorithm with an account manager, and offers real-time analytics.

Not right for: buyers who want creator fees bundled into one price, or a process that is fully done for them without any platform involvement.

12. Sculpt

Sculpt is a social agency that treats LinkedIn as a priority channel. Its influencer work covers identifying key opinion leaders, negotiating contracts, coordinating deliverables and reporting to leadership. It uses fixed-value Content Units rather than hourly retainers for content, but publishes no influencer price. It does not describe a creator vetting process, so ask.

Not right for: buyers whose main need is influencer vetting depth, unless Sculpt can show its process on a call.

13. Leadtail

Leadtail is a B2B social agency with six practices, one being B2B influencer marketing. Its own description of that service is brief, and most specifics come through client testimonials, which refer to analysis of influencers and measurement. It suits a team that wants influencer work joined to managed social and advocacy.

Not right for: buyers who want a dedicated LinkedIn creator programme with published detail.

14. Obviously

Obviously is a general influencer agency with a B2B industry page, offering custom influencer networks. It cites influencer background checks, custom reporting and real-time dashboards. No LinkedIn-specific service is described on that page.

Not right for: LinkedIn-first B2B programmes, unless it can show relevant work in your category.

15. NinjaPromo

NinjaPromo is an on-demand marketing agency sold by hours: from $4,000 a month for 40 hours up to enterprise plans, with discounts for longer terms and a 30-day notice period to cancel. It says it does not mark up creator payments, so those sit on top of the hours. Its stated vetting uses fraud detection, with checks on growth patterns, engagement, demographics and bots. It tracks reach, conversions, CPA and brand lift. It describes draft review and final client approval.

Not right for: buyers who want one all-in price per placement, or a LinkedIn specialist.

How to choose a B2B influencer agency

The table shows what each agency says. These checks show whether it can do it.

• Start with your channel. If your buyers are on LinkedIn, ask what share of the agency's work runs there. Our shortlist of the best LinkedIn influencer marketing agencies goes deeper on that.
• Ask what the price includes. Some agencies quote fees and pass creator payments through, while others bundle them. Compare the all-in cost per placement.
• See a vetting rejection. Anyone can claim to vet. Ask what would disqualify a creator, and for an example of who they turned down. Our guide to finding B2B influencers on LinkedIn covers what to look for.
• Ask for a sample report. Look for who engaged, by company and role. A report of impressions alone will not tell you whether your buyers saw the post. Our article on measuring B2B influencer marketing ROI sets out what to request.
• Check who controls the content. Ask who writes the brief and who has final approval. A good LinkedIn creator brief leaves room for the creator's voice.

You may not need an agency at all. LinkedIn's Creator Marketplace lets brands search for and contact vetted creators directly in Campaign Manager. Our comparison of the Creator Marketplace and using an agency explains the trade-off, and the B2B influencer marketing guide covers the basics.

Where Fame fits

If you are a B2B tech or SaaS company focused on LinkedIn and want fixed prices with creator fees included, Fame Influencer is built for that. You can see how we source creators or read how it works for SaaS companies. If you need several platforms or a broad content programme, one of the wider agencies above will likely fit better.
