Build in Public on X: How Indie Hackers Turn Posts Into Users

By CarryFeed10 min readPublished

For an indie product, X becomes useful when posts reach people who might buy, test, or recommend it. The business question starts after the attention: did anyone begin a conversation, sign up, activate, or pay?

This article examines five public founder stories by the mechanism they reveal: community, audience-product fit, multi-channel distribution, failed capture, and growth without a large X audience. The numbers are self-reported unless noted otherwise.

A public post earns business value at the handoff.

The clearest cases combine four things: relevant prior relationships, a product the audience can understand, public proof, and a next step such as a signup, reply, trial, or purchase.

Views, follower growth, and enthusiastic comments sit earlier in the chain. They can signal interest. Attribution requires a trail from the post to the conversation or product action that followed.

Four numbers answer four different questions.

Treat these as four different ledgers. A post can perform well in the first and fail in every stage after it.

Reach
Was the post displayed? Views are not unique people. X says repeat views can count; see its view-count explanation.
Curiosity
Did a relevant person reply, visit, or start a conversation? Replies and DMs can reveal language, objections, and problem urgency. Purchases come later in the trail.
Captured demand
Did the person join a list, request access, or create an account? This is the first stage you can reliably follow beyond the feed. Tag the landing page or ask how they found you.
Paid demand
Did an X-sourced user activate, pay, and stay? Track cohorts or at least source-at-signup. Revenue without source data cannot prove which channel caused it.

Five stories, five different mechanisms

Five stories show where X entered the growth system.

Every case below is a first-person account published on Indie Hackers. The figures are useful clues about a mechanism, but none is a controlled experiment and none independently proves that X caused all reported growth.

Community before conversion

1. Indie Hackers made its X account feel like an extension of the community

Rosie Sherry used the community's existing questions, knowledge, and voices as the raw material for the account.

Editorial illustration: community participation can create a path to users, but it does not prove conversion by itself.

In a 2020 account of running the Indie Hackers Twitter presence, Sherry reported that the account grew from more than 20,000 followers to 39,000, while monthly impressions rose from roughly 600,000 to 3.5 million at one point. She also stated that she did not track clicks, traffic, or conversions. The case therefore documents reach and community participation; it cannot establish customer acquisition.

Her operating idea was to reflect the existing Indie Hackers community on Twitter: ask questions, summarize forum knowledge inside the feed, highlight members, and make the platform useful even when people did not click back. The account had an upstream source of material—the community—and a downstream effect it cared about—participation and recognition.

For a founder, the practical part is the recurring social job. An account can surface useful questions, connect people, or show how customers work. The metric should match that job; Sherry's account leaves the traffic and revenue question unanswered.

Audience-product overlap

2. Replymer shows what build in public looks like when the existing audience is already relevant

The launch began with 11,500 followers and a product aimed at founders using social conversations.

In October 2025, Replymer founder Alex Belogubov reported reaching $3,000 in monthly recurring revenue six days after launch. He wrote that regular posts about progress and problems brought signups and founder DMs, and that some early users became paying customers after follow-up conversations and rapid product changes.

Belogubov already had 11,500 Twitter followers, and three launch-day posts generated a reported 120,000 impressions. Those starting conditions matter. So does the work after each post: people sent DMs or signed up, the founder continued those conversations, the product changed, and some users paid. A new account publishing similar updates would be running a different experiment.

3. INDEXED.pro used X alongside a waitlist, directories, networks, and Product Hunt

Daniel Peris reported that INDEXED.pro approached €2,500 MRR 45 days after its November 2023 launch. The team announced the launch to about 500 pre-launch subscribers and used the founders' Twitter, LinkedIn, newsletter, and professional networks, plus a newer product account with more than 500 Twitter followers.

The launch also included Product Hunt, directory submissions, partnerships, and planned SEO work. Peris described Product Hunt as modest for traffic and sales while crediting it with visibility and backlinks. With so many channels active, the post cannot assign the reported revenue to X alone.

It does identify one X-specific mechanism: customers shared visible indexing results on social media, which Peris said helped acquire new customers. The product produced an outcome people could show, giving customer proof a role in later distribution.

What to record

Keep source-at-signup data across the whole launch mix. If customers share a product result, track the visits and signups that arrive from those shares separately from founder posts.

Attention lost at the handoff

4. Victor's viral post exposed a broken handoff

In a 2022 retrospective on a 30-day build-in-public challenge, Victor reported that the announcement received more than 2,000 comments. He sent interested people directly to a Notion page instead of an email-capture page, then described that choice as a mistake.

The post opens by saying that a 60-person waiting list produced $14 and that the challenge produced $50; later it says the challenge ended with $14. The accounting is internally inconsistent, so it should not be used as a conversion benchmark. The useful evidence is the handoff failure Victor described himself. An open document suited a reach goal. A product waitlist needed an explicit way to request the next update.

5. Some indie products grow with very small founder audiences

A founder can choose X, search, partnerships, referrals, direct sales, or a mix that matches where buyers already look.

In a 2023 Indie Hackers post, Adam K. Stinson said he reviewed hundreds of indie hackers and found only a small minority of successful projects were visibly built in public. He described projects above $15,000 MRR whose founders had roughly 50 to 100 Twitter followers, and pointed to earned media, directories, SEO, referrals, and affiliates as alternative growth paths.

The post omits its sample, selection rules, dataset, and attribution method. That leaves us with a counter-hypothesis from community research rather than a measured base rate. It still widens the comparison set beyond the founders who publicly discuss growth on X.

For a niche B2B tool, direct outreach, integrations, comparison pages, or industry partners may reach buyers faster. A visual creator product may have an obvious social proof loop. The decision depends on where customers already search, compare, and refer.

A useful stop condition

Search for ten recent conversations in the buyer's own language. If you cannot find them, keep X as a small test and spend the main distribution effort elsewhere.

Build-in-public counterpoint

Check the customer, the proof, and the handoff.

Three checks are enough to decide whether X deserves a focused experiment. A weak answer sends the main distribution effort elsewhere.

Can you find current buyer conversations?
Search the customer's exact problem language alongside #buildinpublic. Collect ten recent conversations where the buyer, problem, and context are identifiable.
What proof can you publish safely?
Use a tested decision, an anonymized pattern, a product constraint, a before-and-after process, or a result the customer has approved. Choose material that helps the reader understand the product's work.
What happens after someone cares?
Choose one observable action: a reply with context, list signup, access request, tool run, trial, call, or purchase. Save the language and objections you hear in the product, onboarding, search content, or email list.

Run one small distribution experiment.

Use one customer problem for one or two weeks. The result should show where the trail stops: conversation, signup, activation, or payment.

Listen, then join with evidence
Use public X search to locate recent posts containing the customer's own words. Add a real observation, example, source, or clarifying question where it helps the conversation.
Publish one artifact with one action
Turn a repeated question into a build note, teardown, test result, changelog entry, comparison, or customer-approved outcome. Connect it to the single next step chosen above.
Review what happened downstream
After one or two weeks, record relevant conversations, captured demand, activation, paid conversion, and any product change caused by what you learned.

Frequently asked questions

Does build in public work for indie hackers?

It can work when the audience contains likely customers or trusted introducers, the product creates credible public proof, and every campaign has a measurable next step. It is less useful when most attention comes from other founders who are not buyers.

Do I need a large X audience before launching?

No. A relevant small network can outperform a large unrelated audience, and many indie products grow through search, partnerships, referrals, directories, or direct sales. A large existing audience changes the starting conditions of a launch story, so record it when comparing results.

What should an indie hacker post on X?

Post evidence connected to the customer's problem: tested decisions, useful constraints, product changes caused by feedback, small demonstrations, customer-approved outcomes, and clear questions. Avoid turning private customer work into content without consent.

Are impressions a useful build-in-public metric?

They show distribution, but X states that views are not unique and repeat views can count. Pair impressions with relevant replies, profile or landing-page visits, signups, activation, paid conversion, and retention.

Should build in public be my only growth channel?

Usually not. X is rented distribution with a fast-moving feed. Keep at least one compounding channel you control or can revisit, such as email, search content, referrals, integrations, a community, or customer-generated product proof.
