The Build in Public Playbook: How to Turn Followers Into Customers
90% of your build-in-public audience will never buy from you. Here's the data-backed playbook founders like Pieter Levels and Marc Lou use to turn the other 10% into real revenue.

You’ve been building in public for six months. You’ve got 3,000 followers. Your “Day 47: shipped the settings page” tweet got 89 likes.
And your MRR is still $0.
This is the dirty secret of the build in public movement. Most founders who do it end up with an audience of other founders who will never buy their product. They confuse applause for demand. Likes for revenue. Followers for customers.
The data backs this up. According to a 2024 analysis by Blazly, a typical build-in-public audience breaks down like this: 40% other entrepreneurs, 30% startup enthusiasts and students, 20% general business audience, and only 10% actual potential customers. That means 90% of your engagement comes from people who will never convert.
But here’s the thing — the founders who do build in public right are printing money. And they have the receipts.
The 90/10 Problem
If 10,000 people follow your build-in-public journey, roughly 1,000 are realistic customers. If 2–5% of those trial your product, that's 20–50 trials. At a 10–25% trial-to-paid rate, you're looking at 2–12 paying customers from 10,000 followers. This is why follower count is a vanity metric.
The Founders Who Actually Made It Work
Before we get into the playbook, let’s look at real numbers from founders who turned transparency into revenue. Not theory — receipts.
Pieter Levels built Photo AI to $138K MRR by late 2025, primarily through his 600K+ follower X audience built over a decade of shipping in public. Photo AI accounts for roughly 70% of his total income. His portfolio hit $3.1M ARR as a solo founder with zero employees. (Sources: Fast-SaaS, SoftwareSeni)
Marc Lou crossed $1M cumulative solo-founder revenue by August 2024, with 85% profit margins. At the time, 7 active products generated ~$62K/month combined — all fueled by his build-in-public presence on X. He tried 27 businesses before hitting that number.

Rob Hallum scaled SuperX from zero to $13K MRR in just four months, with 95% of users coming directly from X. A single high-performing post added ~$1K MRR in 24 hours. (Source: Rob Hallum YouTube, December 2025)
Arvid Kahl grew FeedbackPanda to $55K MRR in two years with zero ad spend, then sold the company. His build-in-public approach on Twitter grew his audience from 400 to 8,000 followers in 11 months. (Source: Indie Hackers Podcast #140)

Notice what these founders have in common. None of them just posted “shipped a feature today” and hoped for the best. They all had a system.
But there’s a more important pattern. A study of 92 founder case studies by Wovly found that a founder with 340 followers generated $18,200 in revenue at a 15.3% conversion rate — outperforming another account with 10,000 followers. Another founder hit $45K/month from just ~700 followers.
The lesson: audience size is irrelevant. Audience fit is everything.
The 90/10 Fix: A 5-Step Playbook
Here’s how to stop attracting fellow builders and start attracting buyers.
The Build-in-Public Revenue Playbook
Step 1
Define Your ICP Before You Post
Before writing a single tweet, ask: who is my actual buyer? If you're building project management software for agencies, your ICP is agency owners — not indie hackers. Blazly's 2024 research found that founders who make product decisions based on build-in-public feedback (instead of ICP research) end up with 'feature bloat, positioning confusion, and a product that appeals to startup enthusiasts but fails to solve real customer problems.' Write for the buyer, not the crowd.
Step 2
Post Problems, Not Progress
Revenue transparency posts get 4–8× higher impressions than generic advice or motivational tweets (Monolit, 2024). But the posts that actually convert aren't 'Day 47' updates — they're posts that describe the specific problem your product solves in your customer's language. 'Spent 3 hours this week on invoicing because my tool sucks' > 'Shipped the invoice feature.' The first attracts people with the problem. The second attracts builders.
Step 3
Use the 60/20/20 Content Mix
60% value content (insights, frameworks, tactical tips your ICP can use today). 20% social proof (customer results, testimonials, before/afters, metric milestones). 20% conversion content (product mentions, CTAs, launch announcements). If your feed is 90% value with zero product mentions, followers literally don't know what you sell. Products with reviews are 270% more likely to be purchased (Northwestern Spiegel Research Center), so work social proof into every week.
Step 4
Reply Your Way to Distribution
Wovly's 92-case analysis found one founder gained 800K impressions in 12 days from a zero-follower account — just by replying to larger accounts. Another went from $0 to $20K in 2 months using a 'first commenter' tactic. On X, replies get distributed 27× more than likes, and conversations 150× more. Find 5–10 accounts your ICP already follows and become a consistent, high-value voice in their replies.
Step 5
Make the Next Step Frictionless
Founders who actively respond to comments convert 2–3× more followers into customers than those who 'post and disappear' (Monolit, 2024). But engagement alone isn't enough — you need a clear conversion path. Link to a free trial, waitlist, or demo in your bio and in 20% of your posts. Rob Hallum found that a single optimized post generated more sign-ups than his initial launch tweet and added ~$1K MRR in 24 hours.
Build in public is a compounding strategy — the payoff comes from consistency, not any single post.
The Timeline You Should Actually Expect
Building in public isn’t a quick hack. It’s a compounding asset. Here’s what realistic growth looks like based on data from Teract AI and BetterLaunch, both tracking indie hacker accounts:
Realistic Build-in-Public Growth Timeline
Months 1–3
0–500 followers
Foundation phase. 1–3 original posts/day, 5–10 thoughtful replies. Growth is slow. You're finding your voice and getting zero engagement. This is normal.
Months 3–6
500–2,000 followers
Consistency phase. Weekly progress threads. Revenue/metric transparency posts start outperforming. Algorithm begins recognizing you. First inbound DMs from potential users.
Months 6–12
2,000–5,000 followers
Momentum phase. Posts start reaching beyond your followers. Collaboration requests increase. With ~4,000 followers, a well-timed launch can generate 300–800 signups.
Months 12–18
5,000–10,000+ followers
Compounding phase. Your content is now a distribution flywheel. Individual posts can spike revenue. One indie hacker documented $322 → $2K MRR in 60 days at this stage.
The compounding effect is real but slow. After six months of consistent, honest sharing, you will have an engaged audience that understands your context, trusts your judgment, and has developed real affinity for what you are building. That is the actual return on building in public. It is not follower count. It is accumulated trust.
The Uncomfortable Truth: When Build in Public Doesn’t Work
Build in public is not a universal strategy. It works best when your ICP overlaps with the audience that follows startup journeys.
Great fit:
Developer tools and APIs
SaaS targeting technical users, indie hackers, or creators
Products where founders are the buyers (design tools, analytics, marketing tools)
Poor fit:
Enterprise software with complex sales cycles
Products for non-technical verticals (healthcare admins, logistics managers)
Anything where your customers aren’t on X
As Blazly puts it: “If your ideal customers are busy healthcare administrators, they’re probably not scrolling Twitter to follow startup journeys.” This is why build in public works amazingly well for someone like Pieter Levels (selling to devs and creators) but would be useless for selling compliance software to hospital systems.
There’s also a growing critique on Hacker News that much of the “build in public” ecosystem is meta — founders building tools for other founders who are building tools for other founders. As one commenter put it: “If you’re building in public there’s a 99% chance you’re going to end up building products for other indiehackers.”
That’s not necessarily bad. If indie hackers are your ICP, lean in. Just be honest about it.
The Real Metric That Matters
Stop tracking follower count. Start tracking ICP follower percentage — what share of your audience actually fits your buyer profile. A 340-follower account generated $18.2K at 15.3% conversion. A 10K-follower account with the wrong audience generated nothing meaningful. Audience fit beats audience size every time.
The Meta-Play: Build in Public + SEO
Here’s what almost nobody talks about: building in public on Twitter is great for short-term distribution, but your tweets have a half-life of about 18 minutes. They don’t compound the way search traffic does.
The founders who build real, durable distribution combine social transparency with content that ranks on Google. They turn their build-in-public insights into blog posts, and those blog posts bring in traffic for years.
Pieter Levels doesn’t just tweet — he’s been writing on levels.io for a decade. Arvid Kahl runs The Bootstrapped Founder newsletter and blog. Marc Lou publishes a Substack.
The pattern is clear: social for reach, SEO for compounding. Your tweets start the conversation. Your blog captures the demand. If you’re already sharing lessons publicly on X, you’ve done the hard part — you have the raw material. Now you need a system to turn those insights into content that ranks and compounds over time.
That’s where most founders hit a wall. You’re already spending time building the product and posting on Twitter. Who has time to also write 2,000-word blog posts, do keyword research, and optimize for search?
The Compounding Math
Only 10% of blog posts compound over time — but they generate 38% of all traffic (HubSpot). If you publish 2 posts a week while building in public, in 6 months you'll have 50+ posts working for you 24/7. Your tweets disappear in hours. Your blog posts rank for years.
The Bottom Line
Build in public is a legitimate $0 distribution channel. The data proves it. But it only works if you’re intentional about who you’re building for.
Stop posting diary entries for other founders. Start posting use cases for your actual buyers. Use the 60/20/20 content mix. Reply your way into the feeds your ICP already follows. And make the jump from social to SEO-driven content before your competitors do.
The founders pulling $10K–$138K MRR from their X audiences aren’t lucky. They’re running a system. Now you have the playbook to build yours.
