Latest / Solopreneur Sessions with Fexingo: One-Person Businesses, Freelancing, and Independent Work / How a Solopreneur Built a Six-Figure Newsletter on LinkedIn Alone
Transcript
- Lucas: So you know how every business podcast for the last three years has been telling solopreneurs to start a newsletter, build an email list, own your audience — the whole 'rented land is dangerous' mantra. Luna: Right. Substack, Beehiiv, ConvertKit — pick your platform, grow your list, don't depend on the algorithm. Lucas: Exactly. But today I want to talk about someone who did the exact opposite. A solopreneur who built a six-figure newsletter entirely inside LinkedIn. No external email platform, no website, no landing page. Just LinkedIn posts and LinkedIn's native newsletter feature. Luna: That feels risky. Rented land on steroids. Lucas: It is. And we'll get to the risks. But the numbers are real. This person — let's call her Sarah, she's a marketing consultant in Atlanta — started a LinkedIn newsletter in March of 2024. By December of 2025, she had 14,000 subscribers and was generating about $8,000 a month in subscription revenue. That's just under six figures annualized, from a single content stream on one platform. Luna: Wait — how do you charge for a LinkedIn newsletter? LinkedIn doesn't have a native paywall. Lucas: It doesn't. So she used a workaround. Every week she'd publish a free preview on LinkedIn — about 30 percent of the full newsletter. Then at the bottom of every post, she'd include a link to a paid subscription on a third-party platform — she used Stripe with a simple membership page. But here's the key: she never asked people to leave LinkedIn to read the content. The free preview was substantial enough to demonstrate value. The paid tier was behind a link, but she framed it as 'deep dives and templates' rather than 'paywall.' Luna: So the LinkedIn post itself was the marketing engine. The paid subscription was almost an upsell. Lucas: Exactly. And the growth came from one specific content strategy. Sarah didn't post about newsletter growth. She didn't post about how to build a business. She posted about a very specific niche: how mid-career marketers can transition into product marketing roles. That's it. Every single post was a tactical tip about product marketing — frameworks, case studies, resume advice. Luna: Super narrow. But that makes sense — product marketing managers earn good salaries, so the audience has disposable income. And they're career-motivated, so they'll pay for advancement. Lucas: Right. She understood her audience's willingness to pay before she ever asked for money. She spent six months just posting free content, building trust. Then she launched the newsletter with a single post titled 'I'm Starting a Paid Newsletter — Here's What You'll Get.' And she was transparent about the price: $15 a month or $150 a year. That first post converted 230 subscribers in the first week. Luna: Two hundred thirty from one post. That's impressive. But it also suggests she already had a strong following by then. Lucas: She did. She had about 8,000 followers at that point. But she'd built those followers entirely through commenting on other people's posts, not through her own viral content. She'd spend twenty minutes a day leaving thoughtful comments on posts by product marketing leaders, adding value, not self-promoting. That drove people to her profile, where they'd see her consistent posting. Luna: So the classic 'commenting strategy' — but executed with discipline over months, not weeks. Lucas: Exactly. And once the newsletter launched, she maintained a rhythm: one free LinkedIn post per week, one full newsletter sent to paid subscribers. She never missed a week for eighteen months. That consistency built the habit. Luna: I want to pause on something. The donation segment actually fits here, because this kind of deep-dive case study is exactly the content we're able to make because we don't run ads. If these conversations have moved your work forward in some small way, the way Sarah's content moved her audience — we deliberately keep this show ad-free. If you want to support that choice, the link is buy me a coffee dot com slash fexingo. No pressure, just a way to keep this going. Lucas: Yeah, we mean that. We don't interrupt with ad reads, no sponsors. It's just us digging into a story. So if that matters to you, buy me a coffee dot com slash fexingo. Appreciate it. Luna: Alright. Back to Sarah. So she's got 230 paid subscribers in week one. What happened next? Lucas: Growth slowed, as it always does. By month three she was at 410 subscribers. Month six, 680. The key inflection point came when she introduced a referral program: if you referred a friend, you got a month free. That drove a second wave. By month twelve she was at 1,200 subscribers. Luna: And at $15 a month, that's $18,000 a month — but that's before churn and Stripe fees. Lucas: Right. Her actual monthly revenue was around $12,000 because of churn. She lost about 8 percent of subscribers each month, which is high. But because she kept adding new ones, the base grew. By month 18 she had 1,800 paid subscribers, revenue around $16,000 a month, but then churn started climbing. Luna: Why did churn increase? Lucas: Two reasons. First, the content became repetitive. Product marketing frameworks only go so deep. She was writing three newsletters a month — one deep dive, one template, one case study. After 18 months, she'd covered most of the core topics. Second, LinkedIn's algorithm changed in early 2026. They started suppressing posts that included external links, even in the comments. Her free preview posts got less reach, so fewer new subscribers entered the funnel. Luna: That's the rent coming due. The platform giveth and taketh away. Lucas: Exactly. She adapted by shifting the free preview to a text-only version with no link, and moving the link to her profile and a pinned comment. But reach never fully recovered. She's now at about 1,400 paid subscribers, revenue around $11,000 a month. Still a great business, but not growing. Luna: So what's the lesson for solopreneurs listening? Build on LinkedIn, but with an exit plan? Lucas: I think the lesson is: LinkedIn is an excellent customer acquisition channel, but a risky platform for your entire business model. Sarah succeeded because she started with a highly specific, high-willingness-to-pay audience. She also had a very low operational cost — she spent about five hours a week on the newsletter. So even at $11,000 a month, her time investment was reasonable. But she's now working on a Substack as a backup, slowly migrating her best subscribers. Luna: So the strategy is: use LinkedIn for discovery, but build a parallel email list that you own. Lucas: Exactly. The mistake would be to put all your eggs in one algorithmic basket. Sarah's story is a great example of how to ride a platform wave without getting wiped out. She extracted six figures of value from LinkedIn in 18 months. That's a win. But she's also smart enough to know the wave won't last forever. Luna: And she proved that a solopreneur can build a real business on a single platform — as long as they're ready to pivot when the platform shifts.
