How to run B2B influencer marketing that books demos

By Deb MukherjeeThe true generalist

At Numeral, a good creator post usually meant three to five demos.

I was the first full-time hire there, and the company went from $0 to $3.2M ARR in 12 months. Creators were a big part of that.

"Deb drove so much demand we turned off cold email. He was doing too good a job." Sam Ross, founder and CEO of Numeral

Most advice on this is written by platforms that sell creators, so this one comes from the buying side. Where I could find outside data, it's linked.

Key takeaways

  • Pay the people your buyers already trust. Follower count tells you very little.
  • Only run a post if it ends in something you can count: a demo, a download or a sign-up.
  • Ask every buyer how they heard about you, because software misses most of what creators do.
  • Disclose every paid post. If a creator gets it wrong, it's still your problem.

Why does influencer marketing work in B2B?

Buyers make most of the decision before they talk to anyone.

6sense's 2025 report found that they pick from their day-one shortlist 95% of the time, and 94% rank their favourite vendors before contacting any of them.

Gartner's 2025 survey of 632 buyers found that 61% would rather skip the salesperson. Another 73% avoid suppliers who send irrelevant outreach.

So you want to be on the shortlist before anyone is shopping. A creator the buyer already follows gets you there, because the post reads like a peer's opinion.

LinkedIn's YouGov survey points the same way, with 82% of B2B marketers who work with creators calling creator campaigns essential for measurable ROI. LinkedIn sells creator ads, though, so I'd hold that number loosely.

Software misses a lot of this. Refine Labs studied 620 conversions over 12 months and asked buyers how they'd heard about the company.

Refine Labs compared 620 conversions over 12 months. When buyers were asked how they heard about the company, podcasts got 53% of revenue ($11.4M). Software attribution gave them 0%. Read the study. It's one agency's data, so treat it as a strong hint.

Who counts as a B2B creator?

I call the best ones ICP influencers: practitioners who've lived the problem you solve and have a real audience, even a small one.

At Numeral that meant brand owners, heads of ecommerce, CFOs and COOs at direct-to-consumer brands, people who'd been the buyer themselves.

They don't have to call themselves creators.

Plenty post weekly because they like it or because it helps their career, and if they have a captive audience in your niche (a newsletter, a podcast, an active feed), they count.

Roughly, there are three kinds. Practitioners with a small, real audience are the cheapest and the most trusted, and also the hardest to find.

Niche creators with a newsletter, podcast or channel price accordingly and are easier to find on creator platforms. Big names are worth it for a launch and rarely for anything ongoing.

Three sizes of creator, three sizes of horn.

I'd take a head of ecommerce with 2,000 engaged followers over a generic tech influencer with 100,000.

Boring niches work too. Numeral sold sales-tax compliance, about as unglamorous as B2B gets, and creators still brought demos.

What should be true before you start?

You need sharp positioning, because creators repeat what you give them. At Numeral the line was "sales tax is not optional," and every post leaned on it.

You also need an action you can count, whether that's a demo, a resource download or a webinar sign-up.

Likes and comments don't tell you anything, and the product has to hold up once the creator has sent someone over.

Creators amplify demand that's already there, so fix the product first.

I wrote about the opposite problem, startups that raise first and learn who their customers are later, in You raised a round but forgot to build a business.

One reported example: Gamma added micro-creators only after its product was already spreading by word of mouth, according to interviews with its CEO.

How do you find and vet creators?

Finding them

If you know the niche, you probably know a few already. At Numeral I knew most of the ecommerce operators, so my message was close to "want an extra $300 next month?"

If you're new to it, search LinkedIn and X for the words your buyers use about the problem and list who's posting. Ignore follower counts and look for people who sound like the buyer.

Then connect and send a short message saying what you do, for whom, and whether they'd partner.

There's no one button that returns ten perfect creators, so it's manual work. If your niche has almost none (legal, say, or manufacturing), go more generic and settle for one or two.

If you can't find people yourself, start with creators already listed on Passionfroot or Limelight.

They cost more, but you can start this week, and the people commenting on their posts are your next shortlist.

Your own customers can be a source too, since some have audiences and never think of themselves as creators.

One founder paid six customers $100 each to post and reported 122 free trials and 14 paid subscriptions, which is a single self-reported test but a sensible idea.

Vetting them

Run every name through this before you pay.

Scorecard

Is this creator worth paying?

0 of 5

Tick what's true for the creator you're looking at.

A rule of thumb from how I work, not a study.

Pods happen. One founder who paid five LinkedIn creators $1,250 reported that two sent no visits at all and guessed they were engagement pods.

The other three brought 19 paying customers at $99 a month. Both numbers are self-reported.

How much should you pay?

I've paid anywhere from $250 to $5,000 per post, and the price told me less than the fit did. What matters is whether the audience looks like your buyer.

What creators cost, side by side

Hover or tap a bar for the detail.

Sources: Favikon's study of 136 LinkedIn creators, via ContentGrip, and my own spend at Numeral. The retainer is per month, the rest is per post.

In that same article, video, carousels and exclusivity add 20% to 80% to a post.

Newsletters and podcasts price by audience. One publisher's own rate card puts enterprise tech, SaaS and AI newsletters near a $92 CPM, with developer-only audiences far lower.

It's a vendor's own number, so use it as a range.

On YouTube, a channel with about a thousand subscribers and a few hundred views a video can often be hired for around $1,000 for a dedicated video.

You can't predict which video takes off, so skip paying for views and negotiate down from the first quote.

A few habits help. Negotiate, because the founder above reported prices dropping two to three times when he pushed. Pay after the post is live.

Go for several months with the same person over one-off posts, and set a budget per month.

At Numeral I kept a few creators on monthly retainers, from about $1,000 to $5,000 depending on the person.

To model a first month, plug in your own numbers below. The example uses three to five demos per post, which is what I saw at Numeral, with placeholders for the rest.

The three to five demos per post is what I saw at Numeral. The rate and the customer value are examples, so swap in yours. Spend rounds down to whole posts.

How do you pitch and brief a creator?

Keep the pitch under two lines, because a long one gets ignored and on some platforms gets reported as spam. This is what I'd send, adapted from what I used at Numeral.

Pitch builder

Write the two-line message

The defaults are the Numeral version. Replace them with a result your customers would recognise.

It works because it leads with a result for people like their audience and asks for one thing. If you don't have a customer result yet, get one before you pitch anyone.

Two lines and one ask.
Two lines and one ask.

For the brief, be flexible. Some creators want you to write the post, some want an angle, and some write the lot and show you a draft. Whichever they pick, send them:

  1. the one thing you want, a demo, a download or a sign-up
  2. a tracked link for it
  3. the angle, meaning the pain in the buyer's words
  4. one customer result they can quote
  5. anything you can't back up, so they steer clear of it
  6. how many review rounds there are and how fast you'll reply

A dedicated post or video beats a passing mention, since people skip around and a one-line mention is easy to miss and impossible to track.

And don't script every word, because a post that doesn't sound like the creator reads as an ad.

Public sponsored posts for Numeral from operators who were already customers tend to follow one shape:

  1. a story from the creator's own life, such as the day they found out what sales tax really takes
  2. the problem in the buyer's words
  3. the product in one line, with its proof, like a guarantee or a customer count
  4. a plain "this post is sponsored"
  5. one next step, such as a comment prompt or a link

What do you need to know about contracts and disclosure?

You're responsible for what creators say on your behalf. In the FTC's words: "Your company is ultimately responsible for what others do on your behalf."

The FTC expects brands to tell creators what they can and can't say, to tell them to disclose, to check what they post and to act on problems.

The FTC's rules for influencers are specific:

  • A free or discounted product counts as a material connection, so disclose it even if nobody asked.
  • The disclosure goes with the post, not on a profile page or behind a "more" click, and in a video it goes in the video itself.
  • Plain words work: "ad," "sponsored" or "paid partnership." Skip "sp," "collab" and "ambassador."

Each platform has its own label. LinkedIn's brand partnership label works on public posts, X's paid partnership label replaces #ad, and YouTube has a paid promotion setting.

For the contract, I'd cover the points below. It's a checklist and not legal advice, so have a lawyer look at your template once.

  • what they deliver, in what format and by when
  • how many revision rounds there are and who signs off
  • whether you can repost the content or run it as an ad
  • which competitors are off limits, and for how long
  • the payment amount and due date, with payment after the post goes live
  • what happens if either side backs out after work starts
  • that they use the platform label and the word "sponsored"
  • the link or code you'll track

Exclusivity costs extra, 25% to 50% more in the Favikon article. One creator who promoted us later moved to a competitor, which is normal unless you've paid to prevent it.

Which channels work for AI and SaaS?

It depends on where your buyer already learns, so pick the tab that matches.

Pick a channel

Where does your buyer already learn?

The default for B2B.

AI and developer products have an extra option, which is to go free first.

Offer free features to a newsletter, a builder community and a creator who needs a demo video, and aim for two or three posts a month.

For scale, Replit went from a $1,000 pilot to a creator program above $300,000, according to a case study published by Passionfroot. That's a vendor's case study, so take it as directional.

How do you run a launch week?

Space the posts out. Ten aligned creators across one week beat the same ten spread over a quarter.

Stagger the posts so the launch gets a full week of attention.
Stagger the posts so the launch gets a full week of attention.

Two days before, creators tease the launch. During launch week one creator posts per day, with customer posts in between.

On launch day every creator reposts and comments on the main announcement. The week after, you put out a press release and each creator posts once more.

Aim for at least ten creators, paid or free. I'd budget $500 to $2,000 per paid post for AI and B2B creators, and lower is better.

How do you measure it?

You're not selling soda on the internet, so views and likes don't matter. Demos and sign-ups do.

There are two ways to count them. The first is to add "How did you hear about us?" to your demo form, with options like LinkedIn, X, YouTube, newsletter, podcast, referral and Google.

The second is to give each creator a unique link or code and put it in the first comment or the bio.

People remember a creator even if they Googled you later, which is why the form question catches what links miss.

I'd skip attribution software for this, because the Refine Labs numbers above show how much it misses.

Ask every buyer how they heard about you, then count.
Ask every buyer how they heard about you, then count.

After a post goes up, reply to every comment (or have the creator do it) and send demo requests straight to a person, not a queue.

Then tell the creator how it went, even if the results were small.

The founder who paid customers $100 a post reported that about 60% of his paid conversions came from re-targeting people who reacted.

Have someone ready to take the demos, too. At Numeral, creator posts filled the calendar fast enough that we added a sales rep within a couple of months.

Read results per creator, demos first and then customers, and drop whoever brought none.

To check whether the brand is working, I ask a friend with a decent audience to post "What do you use for [your problem]?"

If fewer than seven in ten replies name you, the work isn't finished.

Run it from their account. Replies to your own post are polite.

How do you keep it working?

Keep a pool of about ten creators and use three a month, so no audience sees you too often. Multi-month work beats one-off posts, since people know a one-off is paid.

Creators fade. Numeral's biggest creator, signed before I joined, cost about $5,000 a month and worked well for six months, then stopped working because everyone knew the posts were paid.

Creators also bring mid-market and smaller deals. Enterprise deals come from roundtables, conferences, referrals and account-based work.

One analysis reports that fewer than 10% of Gamma's creators produced about 90% of its reach, citing its CEO.

I'd expect your own split to look similar, with a few creators doing most of the work.

If a creator goes quiet, follow up once after a week and move on. If one says no, ask who else they'd recommend, since people who decline often point you to a peer.

If someone goes quiet after you've paid, that's why I pay after the post goes live.

A platform is worth considering if you have more budget than time. Passionfroot also handles contracts, payments and reporting, though creators on a platform cost more than the quiet practitioners you find yourself.

You can also boost the best posts as ads. LinkedIn now lets brands sponsor any member's post as an ad, and the member has to approve it.

I'd try it on the two or three posts that already performed and compare demos against the organic run.

Don't expect direct attribution: one B2B marketer I spoke to measures it by impressions across several touches and sees no direct conversions.

The mistakes I see most are a creator outside your ICP, buying a single post (it reads as an ad), chasing views, paying before the post is live, skipping the label and scripting every word.

What do the first 30 days look like?

In week one, pick one objective, build the tracking (the form field and the links) and write a list of 20 creators.

In week two, vet it down to 10 with the scorecard, send the two-line message to all of them and agree terms with whoever replies.

In week three, run the first three posts with the right labels and links. In week four, read the form answers, check demos per creator and decide which three go into the rotation.

For the form field, I'd use "How did you hear about us?" with the options LinkedIn, X, YouTube, newsletter, podcast, referral, Google and "other (please tell us)."

For the tracker, keep one row per creator with the date posted, platform, cost, link, demos, customers and notes.

If you're stuck on one go-to-market problem while you do this, apply for office hours.
