2025 B2B Influencer Marketing Trends(5)

The team at LimelightHQ - a B2B2 creator platform- is again with a new report. As I have written in the past, B2B influencer marketing is on the rise, and tech companies like Notion, Clay, ActiveCampaign, Wix & more are investing heavily in this distribution channel,
This week David Walsh and the team put together a report on 5 trends in B2B influencer marketing and here are my summaries.
Shift in buyer behavior - Since buyers have become more aware of paid ads and outbound tactics, executing demand capture in partnership with creators in the best bet as of 2025. In fact, 83% of B2B buyers prefer a rep-free sales experience, relying on digital content, peer recommendations, and expert insights to guide purchases.
LinkedIn has become the go-to for B2B social selling - With the launch of LinkedIn Thought Leader ads, it’s evident, that LinkedIn is no longer just a networking platform. Executives-tuned creators are reshaping demand generation on LinkedIn by embedding their brand messages within authentic, creator-driven narratives that buyers trust.
The playbook to run B2B influencer marketing campaigns
Prioritize long-term partnerships
One-off posts drive limited impact. Sustained creator collaborations (biweekly or monthly posts) stack trust and feel more authentic.
Leverage video content
LinkedIn™ users are 5x more likely to engage with video than other post types. Viewers retain 95% of video messaging vs 10% of text (Insivia).
Amplify scale of impact
Analyze metrics like engagement, CTRs and sign-ups to see which posts resonate most. Turn these organic posts into sponsored ads.
Proactively engage warm leads.
Integrate ‘most engaged’ prospects into your CRM, offering low-friction incentives to move them down your funnel (capture and convert demand).
Create cohesive campaigns.
Use one platform to manage briefs/approvals and give clear messaging guidelines, but allow creators flexibility to adapt content to their style
Leveraging AI in optimizing campaigns - David, the CEO of Limelight confesses; having 100s of executives that running influencer marketing campaigns is marred with challenges like unstructured communications, time-consuming research processes, and more. However, leveraging AI can help us move faster, make smarter decisions, and optimize influencer partnerships with ease.
Expert Webinar
How to prioritize consistent experimentation
Canberk Beker, a LinkedIn ads expert and the founder of ROASted was recently hosted on a Stacking Growth episode by Refine Labs. Here is the summary from the 28 minutes episode;
Prioritize quality over quantity in content creation, focusing on developing one well-thought-out campaign per month or quarter to enhance brand authenticity and audience connection.
Embrace the philosophy of asking for forgiveness rather than permission when pushing boundaries and trying new marketing approaches, leading to better results and significant breakthroughs.
Embrace an experimental mindset in B2B marketing by shifting the focus from achieving targets and increasing budgets to fostering growth and innovation through strategic risk-taking.
A month ago Canberk Beker shared an experimentation analysis on a LinkedIn post worth checking out. Here is the summary;
Question: Which retargeting audience converts better?
Hypothesis: We should see higher meeting booked numbers when targeting website visitors compared to people engaging with ads or watching videos on Linkedin.
Dates: Nov 10 – Dec 19
Budget: $35K
Results:
• The website audience generated 12% more meetings booked with a 1% higher cost per meeting booked.
• There was no difference in the meeting booked-to-pipeline conversion rate between the audiences.
• The Linkedin-native audience had cheaper distribution costs and better total audience penetration—but this did not translate into more meetings booked.
Answer:
The website audience seems to be converting 'slightly' better.

How Cal AI scaled to $24m ARR under 12 months

I came across a thread on X from this profile - Siro on the insane growth of Cal AI - an app that simplifies calorie tracking scaled to $2m/month in under one year. Here is my breakdown from the 24 threads;
The User Experience (UX) design of the product evokes high activation through three in-built ways: clean user interface, clear-to-action and instant value proposition.
Baking-in psychology triggers into the product
Instead of pitching the product, Cal AI tells users; to lose 2x weight vs doing it alone and tracking & accountability make a difference.
Cal AI breaks down its paywall into 3 steps:
Step 1: “No payment due now” → Low commitment
Step 2: “We’ll remind you before billing” → Reduces fear
Step 3: Visual timeline → No confusion, just clarity
Simple tweaks = higher trial starts.
How Cal AI acquired users without ads;
Personal promo codes that were shared instantly
$5 per friend referral program
Social motivation push; ‘lose weight together ‘
Cal AI’s influencer marketing playbook
Relatable fitness & weight loss struggles → Emotional connection
AI food scanner demo in action → Immediate value
“Fix result” feature → Solves real problems
Lessons from Nikita Bier on advising 50+ consumer companies
The excerpt from X:
After advising 50+ consumer companies over the last year, the one thing that separates those who can execute and those who can't:
Having a full-time designer in the room at all times
I've met with countless companies that have raised millions—and even one that has raised billions—that do not even have a designer on the payroll. This makes product development broken:
1/ You simply cannot have constructive conversations about ideas without visualizing them in real-time
2/ Your experiments will frequently have inconclusive results because users cannot discover features or they misunderstand how they work
3/ There is no one who can galvanize the team with a vision of what the product could look and feel like
And to be abundantly clear: I'm not referring to visual UI or graphics. I'm talking about someone who can think through the fundamental building blocks of product comprehension—like navigation, interaction, and copywriting—and is technically savvy enough to visualize those components in high-resolution
Reddit ads experimentation
Last week, I talked about testing Reddit Ads for 30 days. The first results are in, and here are my thoughts and next steps.👇
Campaign 1
Targeted subreddits: r/LinkedinLunatics
Impressions: 65 919
Clicks: 147
CPC: $0.55
CTR: 0.22%
Signups: 0
% of clicks: 0
Campaign 2
Targeted subreddits: r/LinkedinAds
Impressions: 689
Clicks: 16
CPC: $1.58
CTR: 2.4%
Signups: 2
% of clicks: 12.5%
Campaign 3
Targeted keyword: LinkedIn Ads
Impressions: 28 461
Clicks: 74
CPC: $0.86
CTR: 0.26%
Signups: 2
% of clicks: 2.7%
LEARNINGS
As expected, the niche subreddit r/LinkedinAds is driving the best results in terms of CTR and signups. The issue is that there are only about 100–200 impressions to capture each day.
r/LinkedinLunatics is driving a lot of cheap traffic, but so far, it’s not relevant to what we’re building.
Targeting a keyword seems to be slightly better but still brings in lower-quality traffic.
NEXT STEPS
For the coming week, I’m implementing a few changes based on tips I received from Kris Wojcik (you are awesome! 👏 ): Move my subreddit targeting to only feed placement, not conversation placement. For keyword targeting, switch to only conversation ad placement, not feed.
Apart from that, I'm moving away from a broader channel like r/LinkedinLunatics to r/b2bmarketing to see if it aligns better.
I’ll be back next week with another update.

How to choose the right target market for the ABM pilot
𝘌𝘹𝘢𝘮𝘱𝘭𝘦𝘴
E.g. Certn focused on mid-market tech/SaaS companies in the US that had high hiring volumes and struggled with compliance.
E.g. TestRail focused on regulated industries and remote software teams, where the need for structured test management was higher.
AI UGC ad scripting process
AI UGC ads process i'm seeing work right now
ask perplexity ai to list the reasons pain points this product solves
write 10 hook scripts based on the paint points
then write 100 ad scripts using these hooks in a storytelling format where the product is the hero and the solution
use heygen + 11labs voices to make the ads
edit ads to remove word gaps and add karaoke captions
test all them to see what is working
allocate all budget to top performers
That is all for this week.
