In our B2B creator-led growth report, built on more than 200 interviews and surveys with senior practitioners, 93% of B2B CMOs said they plan to increase their use of creators, and 75% already work with them in some form. The shift is not sentiment alone. It is backed by repeatable, documented performance in SaaS and AI, and it is happening despite LinkedIn's data walls, difficult creator vetting, and immature pricing. B2B teams have started treating creators as a system of growth rather than a series of one-off posts.

This report maps where that shift stands in 2026: how LinkedIn made creators the centre of gravity at Cannes Lions, what the ROI data now shows, why B2B engagement rates favour the niche expert, how effectiveness and efficiency diverge, and which new ad formats are carrying the model forward.

The clearest signal of B2B influence going mainstream came from Cannes Lions 2026, where LinkedIn moved from the periphery of the festival to its centre of gravity for business marketing.

LinkedIn returned as headline partner of LIONS B2B, taking over the rooftop of the Carlton Cannes Hotel for a week of sessions and hosting a dedicated B2B Summit. The platform built a creator space for collaboration and content production, and framed the investment around the growing role trusted voices play in shaping business decisions. As the Washington Post reported, LinkedIn was all in on B2B, with Keke Palmer and Steven Bartlett among the speakers and Colin and Samir hosting a daily briefing. The platform noted that creators on LinkedIn have doubled since 2021.

The institutional signal was just as strong. Ty Heath, LinkedIn's Global Director of Thought Leadership and GTM Strategy, chaired the Creative B2B Lions jury, which awarded 11 Lions from 355 entries. The Grand Prix went to SKF's Faroe Islands Space Program, an industrial bearings brand that skipped the spec-sheet playbook and bought a place in the buyer's memory instead. New LinkedIn research presented at the festival scored 700 B2B campaigns and found that much award-winning work still skips the signals that actually drive purchase.

Cannes did not ask whether creators belong in B2B. It asked how quickly B2B could build the infrastructure to use them well.

The most instructive development at Cannes was structural, not ceremonial. Agencies representing subject-matter experts described a new deliverable model that looks nothing like a B2C sponsorship. Rather than three short-form videos, a brand might commission one cross-posted video, two newsletter write-ups, and a live LinkedIn panel with the product team. The Jess Ramos partnership with Microsoft was built exactly that way: multiple newsletter integrations plus the creator appearing as interstitial content across two live-streamed Microsoft developer events, reaching a professional audience that short-form video alone would never have accessed.

This is the operating shift beneath the headlines. B2B creators are not being bought for reach. They are being integrated into the buyer journey as a distribution and credibility layer that spans formats, channels, and quarters.

The reason budgets are moving is that the return data finally exists, and it is strong enough to survive scrutiny. B2B influencer campaigns have been credited with 5 to 11 times the ROI of traditional channels, driven by third-party validation that brand-owned content cannot replicate. Nielsen research, via TapInfluence, put B2B influencer ROI at roughly 11 times that of traditional advertising.

Our own data sharpens the picture on where that return comes from. In the B2B creator-led growth report, mature always-on creator programs returned 420% ROI at the 12-month mark and produced the strongest long-term media multiplier over a two-year horizon. When the creator genuinely fits the ideal customer profile, ROI reached as high as 20 to 1. The efficiency is a function of fit, not volume.

Influencer touchpoints are overwhelmingly top-of-funnel, which makes last-click attribution actively misleading. The disciplined approach treats creator activity as always-on credibility infrastructure and measures it through influenced pipeline, lead quality, and matched-market lift rather than immediate conversions.

The single most consequential number for how B2B programs should be built is the engagement gap between small experts and large creators, and it runs opposite to B2C intuition.

Our research found that micro and niche B2B experts average roughly 6% engagement, against 1.9% for macro creators. The smaller the audience, the higher the resonance, because a subject-matter expert's followers are a self-selected professional community rather than a broad demographic. The same report found that 90% of B2B-relevant creators have never had a paid sponsorship. The most credible voices in most categories are not only more engaging than large creators, they are also structurally underpriced.

Exhibit 2: In B2B, resonance rises as audience size falls

In B2C, reach is the currency. In B2B, relevance is. A 2,000-follower expert whose audience is entirely your buyers can outperform a creator a hundred times their size.

The trust mechanics explain why. Expert endorsements are 1.7 times more likely than a company's own written content to give a brand the edge over a rival. Being named the top solution by analysts or industry experts was ranked the single most influential trust signal by 37.9% of B2B buyers, ahead of both video and written customer testimonials.

B2B marketers routinely conflate two questions that require separate answers. Effectiveness asks whether the work moves buyers. Efficiency asks whether it does so at a defensible cost. Creator-led growth is now winning on both, but through different mechanisms.

The effectiveness case rests on what thought leadership does to the buying group. Edelman and LinkedIn's long-running research found that 75% of decision-makers say thought leadership prompted them to research a product or service they had not previously considered, and 70% of C-suite executives said it led them to reconsider a current vendor relationship. This works because of the 95-5 rule: at any moment only about 5% of buyers are in-market, and thought leadership is the most efficient way to build demand with the 95% who are not yet ready.

The quality bar is what separates effective programs from noise. The TopRank-Ascend2 2026 report found that 74% of B2B marketers who frequently collaborate with influencers rate their research-based content as very effective, against just 29% of those who do not. The differentiator is original research that a credible expert can amplify, not volume of posts.

Efficiency is where program design does the work. In our data, 58% of active B2B teams now run an always-on creator layer, and 99% of those teams rate it effective. Always-on programs structurally outperform one-off campaigns because credibility compounds: each quarter of consistent expert presence lowers the cost of the next conversion. Combined with tight ICP fit, this is what produces the 420% twelve-month ROI and the 20:1 ceiling.

A campaign spends to be noticed once. An always-on creator layer invests so that every subsequent quarter costs less to win.

The formats that define B2B creator marketing in 2026 are purpose-built for credibility and multi-stakeholder buying groups. Three matter most.

LinkedIn's Thought Leader Ads let brands promote content posted by an individual expert, an employee or an external creator, rather than from the company page. The format carries the trust of a named human into paid distribution, which is precisely the signal B2B buyers respond to. It converts the highest-trust asset in the mix, the expert's own voice, into a scalable media placement.

The single-post sponsorship is being replaced by multi-format engagements that span the funnel: a cross-posted video, newsletter integrations, a live panel with the product team, and interstitial appearances at owned events. This is the model behind the Microsoft and Jess Ramos partnership, and it reflects a deliberate shift from buying a creator's reach to embedding their credibility across the buyer journey.

LinkedIn expanded its creator monetisation and collaboration tooling at Cannes, including a new collaboration feature that pairs creators on shared content. For B2B, co-creation between an expert and a brand's own specialists produces the format buyers trust most: a credible outsider in genuine dialogue with the people who build the product.

The B2B format shift

The convergence of the Cannes signal, the ROI data, and the engagement mechanics points to five priorities for the next 12 to 18 months.

1. Build an always-on expert layer, not a campaign. The 420% twelve-month return and the 99% effectiveness rating both belong to always-on programs. Budget creators as infrastructure, funded across quarters, not as a line item that switches on and off.

2. Prioritise ICP fit over audience size. The 20:1 ceiling and the 6% engagement advantage both come from fit. A niche expert whose audience is your buyers will outperform a macro creator, and cost less. Map creators to your ICP before you map them to their follower count.

3. Anchor programs in original research. The gap between 74% and 29% effectiveness is research. Give your experts proprietary data to amplify. It is the difference between content that compounds credibility and content that adds to the noise.

4. Adopt the integrated package and Thought Leader Ads. Move beyond the single sponsored post. Combine owned distribution, paid amplification of expert content, and live formats to reach the full buying group, including the hidden buyers who never fill in a form.

5. Measure influenced pipeline, not last click. Creator activity is top-of-funnel credibility infrastructure. Judge it on influenced pipeline, lead quality, sales-cycle compression, and matched-market lift. Last-click attribution will systematically undercount it and starve your best-performing channel.

The B2B brands that win the next cycle will not be the ones that spend the most on creators. They will be the ones that build the system earliest: always-on, research-backed, ICP-matched, and measured on pipeline.

Does B2B influencer marketing actually deliver ROI?

Yes. B2B influencer campaigns have been credited with 5 to 11 times the return of traditional channels, and mature always-on programs return around 420% at 12 months, rising to as high as 20 to 1 when the creator fits the ideal customer profile. The return is driven by third-party credibility and improves with audience fit rather than spend.

What is a good engagement rate for B2B influencer marketing?

Niche and micro B2B experts average roughly 6% engagement, compared with about 1.9% for macro creators. Unlike B2C, resonance rises as audience size falls, because a subject-matter expert's followers are a self-selected professional community rather than a broad demographic.

Which platform is most effective for B2B influencer marketing?

LinkedIn is the dominant platform, with more than 1.3 billion members and 76% of B2B marketers ranking it the most effective channel for thought leadership. YouTube is strongest for technical, product-led content, and podcasts punch above their weight with executive buyers.

Why do B2B buyers trust expert creators more than brand content?

Expert endorsements are 1.7 times more likely than a company's own written content to give a brand the edge over a rival, and being named the top solution by analysts or experts is the single most influential trust signal for B2B buyers. Buyers want to learn from someone they already respect who then validates the brand.
