A building in public strategy for B2B SaaS founders

Building in public works, but almost everything written about it is aimed at indie hackers chasing an audience on X for a nine dollar tool. If you run a B2B SaaS company with a narrow ICP, maybe 300 to 3,000 real buyers, that playbook does not transfer as is. A building in public strategy for B2B SaaS founders has to optimize for something different: the visibility of your name inside a small, specific buying committee, not follower count. What you share changes. The channel changes. Even the definition of success changes. Here is what that version of the strategy actually looks like.

What building in public means when your buyer list is short

Building in public means sharing the real, ongoing work of building your company instead of only announcing finished launches. For a consumer product with a broad audience, that means posting revenue screenshots and growth charts to a general startup crowd. For B2B SaaS, the audience is not the internet. It is a specific list of a few hundred to a few thousand people who could plausibly buy from you, and most of them do not care about your MRR chart.

The number that actually matters here is not follower count. It is signal density: the percentage of people who see your content who could actually become a buyer. A founder with 800 LinkedIn followers, half of whom are revenue or ops leaders inside your ICP, has more useful reach than a founder with 80,000 followers who are mostly other founders posting about their own startups.

The mistake founders copy from indie hacker playbooks

Buffer and Ghost made transparency famous by publishing revenue dashboards and salary formulas back in 2013 and 2014. It worked, and it built a loyal community around both products. But Buffer and Ghost are self-serve tools with thousands of individual buyers making a fast, low-stakes decision. A B2B SaaS deal usually involves a buying committee, a budget conversation, and a longer evaluation. Radical revenue transparency does very little for that buyer.

Pieter Levels built a following of over 130,000 people by posting revenue numbers for his indie projects, and Justin Welsh grew past 165,000 LinkedIn followers building digital products in public. Both are real, repeatable playbooks for consumer and prosumer products. Neither was built for a founder selling a $30,000 ACV product to a director of revenue operations.

The actual mistake is treating LinkedIn like a smaller Twitter: writing broad, hot-take content optimized for reach instead of specific, operator-level content that only a few hundred people will fully understand, because those few hundred people are the ones who sign the check.

What to share and what to skip as a B2B SaaS founder

The content that works is the content only you could have written, because it came directly from a real sales call, support ticket, or product decision. Generic startup advice is available from a thousand other accounts. Your actual operating detail is not. Worth sharing:

• The exact objection a prospect raised on a call this week, and how you answered it
• A product decision you made because a specific customer asked for it, and why
• A metric your buyer's boss actually cares about, described in their language, not yours
• A mistake in your go-to-market that cost you a deal, and the fix

Skip:

• Revenue screenshots with no context for a B2B audience that cannot benchmark against you
• Generic founder platitudes that could be posted by any account in any industry
• Negative commentary about competitors or unresolved internal disagreements

A 90-day framework for building in public as a B2B founder

A working 90-day building in public plan has four phases: build the list, pick the channel, publish from real operating detail, and start naming names. Skipping the first step is why most founders quit after three weeks with nothing to show for it.

1. Weeks 1 to 2: build your actual list. Pull the roles and company types in your ICP and, where possible, the real names of people who could buy from you. This list, not your follower count, is what you are optimizing for.
2. Weeks 3 to 6: pick the one channel where that list already spends working hours. For most B2B SaaS ICPs this is LinkedIn, not X or TikTok, because buying committees show up there in a professional capacity already.
3. Weeks 7 to 10: publish twice a week, sourced only from that week's sales calls, support tickets, or product decisions. If you cannot point to the real conversation behind a post, do not publish it.
4. Weeks 11 to 12: start tagging and referencing the actual people and companies on your list when it is genuinely relevant. Direct visibility to 50 real buyers outperforms passive reach to 5,000 strangers.

Which channel actually works for B2B SaaS

LinkedIn is the right default channel for most B2B SaaS founders building in public, because it is where buying committees already spend professional time. X and niche communities work as secondary channels depending on how technical your buyer is.

• LinkedIn: best default for most B2B ICPs, moderate time cost, works because the buying committee is already there in a work context
• X (Twitter): best when your ICP is developer or technical-founder heavy, higher time cost due to noise, weaker fit for enterprise buying committees
• Niche communities such as Slack groups, forums, and vertical Discords: lowest reach but highest signal density, best once you know exactly where your buyers already gather
• Newsletter: slowest to build, but the only channel you fully own, best paired with LinkedIn once you have first traction

If your channel choice also needs to cover direct prospecting rather than just content, our guide on LinkedIn outreach for B2B founders walks through the messaging side of the same channel.

Why this works: the data behind thought leadership and buying decisions

This is not just a hunch. The 2024 Edelman-LinkedIn B2B Thought Leadership Impact Report, based on nearly 3,500 management-level professionals, found that 75 percent of B2B decision-makers say thought leadership content prompted them to research a product or vendor they had not previously considered. Fifty-two percent spend an hour or more a week reading it, and nine in ten say they are more receptive to sales outreach from a company that consistently publishes it.

That last point is the mechanism that actually matters for a founder building in public. It does not close the deal by itself. It lowers the wall before your next cold email or demo request ever lands, because the buyer has already seen your name attached to a real, specific insight instead of a cold subject line.

For more on where the line sits between useful transparency and giving away your edge, Arvid Kahl's guide to building in public without revealing too much and Failory's breakdown of building in public are both useful on mechanics, though neither was written with a narrow B2B buying committee in mind, which is the gap this framework is meant to fill.

What to do this week

Do not wait for a content calendar. Write down 50 real names of people in your ICP who could plausibly buy from you this quarter. Pick LinkedIn. Post twice this week, and source both posts directly from your last five sales calls. That is the entire starting move, and it is enough to know within a month whether the channel and the content are working.

Frequently asked questions

Does building in public actually work for B2B SaaS companies?

Yes, but it looks different than the indie hacker version. Success is not follower growth. It is whether the specific people on your buyer list start recognizing your name before your sales team ever contacts them.

What is the best platform to build in public as a B2B founder?

LinkedIn works for most B2B SaaS ICPs because buying committees are already there in a professional context. X works better if your buyers are developers or technical founders.

How much revenue and metrics detail should I share?

Share direction and strategy, not raw statements. Say what changed and why it mattered, rather than posting exact MRR or churn numbers a competitor could use directly against you.

How long before building in public generates pipeline?

Most founders see the first inbound reply tied to a specific post within 60 to 90 days of consistent, twice-a-week posting sourced from real sales and product conversations.

Is building in public risky if competitors are watching?

Share the strategy, not the exact implementation. A competitor learning that personalized outbound doubled your reply rate is fine. The precise script and targeting logic behind it is not.

None of this replaces having an actual distribution or sales system behind the content. Building in public earns you attention from the right 200 people. What you do with that attention once they reply is a separate problem. If you want a second set of eyes on how that part fits together, see how we work with early-stage teams.
