How a B2B Startup Turned LinkedIn Into Its #1 Lead Source

Most B2B marketing teams know how important LinkedIn is, but don’t necessarily carve out the time necessary to make it work for them. Instead, the platform becomes a place to repost a webinar, announce a product launch, or leave a few comments on industry posts.

But Vector treats LinkedIn like an engine.

In our latest episode of Beyond Social, Vector’s VP of Marketing Jess Cook sat down with our cofounder Reggie Azevedo and ClickUp’s Chris Cunningham and dropped a stat that should make every B2B marketing leader sit up straight: Vector spent roughly $40,000 on ads for all of 2025. 

Their biggest lead source? Organic LinkedIn.

“If we turned that off tomorrow, I think we would die out,” Jess said.

Here’s how she built that engine—and what other B2B teams can take from it.

First things first, optimize for likability

Jess spent 15 years in B2C before crossing over to B2B, and she came in with a clear diagnosis of what her new world was missing.

“We don’t optimize for likeability first,” she said. “So many B2C brands do that first and foremost. They’re like, we just have to be likable. We have to be interesting and different. We have a mascot, or we have some sort of memorable shtick. And I don’t think B2B does that enough.”

That perspective shows up in everything Vector does on LinkedIn. The goal isn’t to push product—it’s to be the brand other marketers point to when someone asks, “tell me a B2B brand that’s doing something cool.” Jess even set a team goal around it for 2025: be your favorite marketing team’s favorite marketing team.

It sounds soft, but it’s not. When likability becomes the strategy, a focus on creating organic content makes sense, and building a network on LinkedIn stops being a chore.

Make posting a habit

Before Vector, before the VP title, Jess made a pact with herself on April 24, 2022: Post on LinkedIn every weekday for a year. She didn’t have a grand strategy (in fact, she often looks back at her old posts and cringes). The point was to just show up.

“The real goal was, I didn’t want to ever have to apply for a job again. I just wanted someone to come find me.”

And it worked. Her CEO Josh hired her in part because she came with a built-in audience—and that same instinct now shapes how Vector hires. A built-in following isn’t required, but it’s a real advantage when a candidate already knows how to think out loud in public.

The takeaway for marketing leaders: An organic LinkedIn strategy doesn’t start with a jam-packed content calendar. It starts with the willingness to be visible and the intent to make posting a habit.

Get your founders involved

Most founders post sporadically, whenever a thought hits them. Jess knew that wouldn’t scale, so she built a repeatable system for Vector’s founders Josh and Nick.

Here’s the workflow:

• A recurring 30-minute interview. Started weekly, now every other week. Jess comes in with timely, relevant questions tied to what’s happening in the business—a product launching in two weeks, a strategic shift, a long-term vision question.
• A Claude project trained on their voice. She gathered all of each founder’s past posts, ranked them top-to-bottom by performance, and fed them into a Claude project as a tone, voice, and structure reference.
• 3 to 5 drafts handed back every two weeks. The founders take it from there—sometimes posting as-is, increasingly remixing into their own voice.

After months of running this loop, the founders have gotten noticeably better at writing their own posts. The system trained them, instead of it being the other way around.

Bring employees into the loop

Vector’s LinkedIn presence isn’t just the founders. The product marketer (Alex Ferdin) came with a built-in audience from her metadata days. The rev ops lead (Sarah McNamara) is one of the most trusted voices in her space. The new demand gen lead (Kelly Arndt) is active in marketing communities and now being coached into posting publicly.

This is where most B2B employee-generated content (EGC) programs stall: getting non-marketers to post. Jess’s answer is less about scripting and more about helping people recognize what’s already a post.

“Kelly will send me stuff and he’ll be like, look at what this campaign is doing. And I’m like, amazing. Go post.”

The blocker, she’s found, isn’t writing skill. It’s noticing. People at Vector are already doing interesting work, having interesting reactions, building interesting things—they just don’t realize those moments are content. Her job is to point at them and say that’s a post.

For engineers, that means talking about what they’re building and why. For customer-facing roles, it’s the interesting fixes they’re finding for customer problems. Nobody has to sell the company. They just have to talk about the cool stuff they’re doing.

Know when to use AI—and when not to

Jess uses Claude daily—for brainstorming, for writing inspiration, even for building a budget tracker she’s now obsessed with. But she’s careful about where she draws the line.

“There’s a level of taste you have to have acquired in order to be really good at knowing where the line is to be drawn with AI. If you don’t have that level of taste or experience yet, err on the side of more human writing.”

Her warning to teams leaning hard on AI: It can never come up with your stories. It doesn’t have your perspective, your experience, the surprising thing that happened in your week. 

That’s exactly why brand and storytelling roles are growing right now. As everything else gets generated, the human stuff becomes so much more valuable.

The version of AI usage that works at Vector sounds like this: AI helps shape, structure, and accelerate. Humans still bring the lived experience, the taste, and the recognition of when a draft is actually good.

The lesson for B2B marketers

If you’re trying to build an organic LinkedIn engine that actually drives pipeline, here’s the Vector playbook in five moves:

1. Set a likability goal, not just a pipeline goal. Decide who you want to be the favorite of, then act like that brand on every post.
2. Get your founders on a posting cadence and build them a system. A recurring interview plus a voice-trained AI project beats waiting for inspiration to strike.
3. Recruit for built-in audiences when you can. Not as a requirement, but as a multiplier on every other thing you’re doing.
4. Coach employees to recognize posts, not write them. The hardest part isn’t the writing, it’s the noticing.
5. Use AI for leverage, not for voice. Let it help you move faster. Don’t let it tell your stories for you.

Vector spent just $40K on ads in 2025 because LinkedIn did everything else for them. They built an audience, a community, and a pipeline channel that they say would tank the business if it went away tomorrow.

The platform is free. The hard part is the commitment to actually show up on it.
