There's a moment most early SaaS founders know well. You've been heads down for weeks, building your product, fixing bugs, second-guessing your pricing page at 1am. And then you realize — nobody outside of your small circle even knows you exist.

That was me about a year into my first SaaS project. I had a product, had paying users, but felt invisible. A friend told me to "just build in public." I honestly thought it was a buzzword. It wasn't. It completely changed how I got users, feedback, and even kept myself accountable.

So let me break this down the way I wish someone had explained it to me.

WHAT IS BUILDING IN PUBLIC?

Building in public means sharing the journey of creating your product openly, in real time. Not just the wins. The failures, the stuck points, the revenue numbers, the bad weeks, the customer conversations that changed your roadmap.

For SaaS founders specifically, building in public is about pulling back the curtain. Instead of shipping quietly and hoping people notice, you document the process as it happens. You share what you're building, why you're building it, what's working, and what's not.

It's less of a marketing strategy and more of a mindset shift. You stop treating your startup like a secret and start treating it like a story worth telling.

WHY DOES IT MATTER FOR SMALL STARTUPS?

Big companies don't need to build in public. They have marketing teams, paid ads budgets, and brand recognition. You probably don't have any of that.

Building in public is one of the few things that levels the playing field. When you share honestly, people root for you. They follow along. They tell their friends. And most importantly, they give you feedback before you build the wrong thing.

I've seen founders get their first 100 users just from a single Twitter / X build in public thread about their journey. No ads, no cold outreach. Just an honest post that resonated with the right people.

The other thing building SaaS in public does is create a content trail. Every post, every update, every milestone thread you write becomes searchable content. That's long-tail SEO happening naturally, without you having to think about it.

The Real Benefits (Not Just the Obvious Ones)

Feedback before you waste months building
When you share what you're working on early, people will tell you what they actually want. Sometimes it confirms what you think. Often it doesn't. Either way, it saves you from building features nobody asked for.

Trust and credibility
Sharing revenue milestones, even small ones, builds trust. When someone sees you went from $0 to $800 MRR and documented every step, they believe in you. It feels real because it is real. Generic marketing copy doesn't do that.

Community before you need it
The mistake most founders make is trying to build an audience after they need users. When you build in public from day one, you're growing a small community of people who are invested in your journey. By the time you launch a new feature or have a promotion, you have people who care.

Accountability
This one's underrated. When you post publicly that you're going to ship a feature by Friday, you're more likely to actually ship it. Public commitments work. I've used this intentionally to push through weeks when motivation was low.

SEO and referral traffic
Every post you write about "building SaaS in public" that gets shared, linked to, or upvoted on Product Hunt is a backlink and a traffic source. Founders have gotten significant organic traffic from a single well-documented journey thread that keeps getting discovered months later.

Common Mistakes Founders Make (And How to Avoid Them)

Sharing too polished
If every update sounds like a press release, people tune out. Real founders have messy weeks. Share those. "We thought this feature would take two days. It took two weeks and we still have a bug" gets more engagement than "Excited to announce our newest feature."

Being inconsistent
Building in public only works if you actually keep doing it. Posting three times in one week and then disappearing for a month breaks the trust you're building. Set a simple schedule and stick to it, even if it's just one update per week.

Only sharing wins
Wins are easy to share. Losses build real connection. Some of my best-performing posts were about a customer churning and what I learned from it, or a launch that flopped. People relate to struggle a lot more than they relate to success.

Not engaging back
Building in public is not broadcasting. When someone comments on your post, reply. When someone asks a question about your journey, answer it genuinely. The relationship is two-way.

How to Build in Public: A Step-by-Step Approach

Step 1: Pick Your Platform (Or Two)
You don't need to be everywhere. Pick one or two platforms and go deep.

Twitter / X is the most common home for building in public in the SaaS world. Short updates, threads, milestone posts. The hashtag #buildinpublic actually has a real community around it.

LinkedIn works well if your SaaS targets businesses or professionals. Longer posts perform better here and the audience tends to be more decision-maker-heavy.

Indie Hackers is built exactly for this. A dedicated platform for founders sharing revenue, learnings, and milestones. Posting here consistently can get you real early users who are founders themselves, often your earliest adopters.

Reddit can work if you find the right subreddit. r/SaaS, r/startups, r/Entrepreneur. Be careful to add genuine value, not just promote yourself. Redditors have a nose for self-promotion.

Product Hunt is great for launch days, but the community there expects a polished product, so use it at the right moment.

Step 2: Decide What to Share
Here's what actually works:

Monthly or weekly revenue/MRR updates
Feature launches and what problem they solve
Customer conversations and what you learned
Mistakes you made and how you fixed them
Behind-the-scenes on how you built something technical
Roadmap updates and why you're prioritizing what you are
Your first paying customer story (everyone loves this one)

A sample post that a founder might actually write:

"Month 4 update: $1,340 MRR. Added 7 new users this month, lost 2. One churned because we didn't have a Zapier integration. That's on our roadmap now. Also rewrote our onboarding flow after watching 5 session recordings. Conversion from signup to active user went from 22% to 38%. Still a long way to go but we're moving."

That's it. That's a good building in public post. No fluff. Just the numbers, what happened, and what you're doing about it.

Step 3: Document Consistently
Consistency beats intensity every time. One update per week, every week, is worth more than five updates in one week followed by silence.

Build a simple system. I use a Notion doc to jot down things that happened each week. Wins, failures, customer feedback snippets, metrics. Then I turn that into a post on Sunday night. Takes about 20 minutes.

Step 4: Engage Your Audience Like They're Real People
Because they are. Reply to comments. Ask people what they think about a decision you're facing. Share polls. If someone says "I've been struggling with the same thing," that's a conversation starter, take it seriously.

Some of my best feature ideas came from people who commented on a post. One user who wasn't even a customer yet gave me a product insight that shaped our roadmap for the next quarter.

Tools That Help You Build in Public

For analytics and dashboards: Baremetrics and ChartMogul let you create public dashboards that automatically pull your MRR and churn data. You can share a public link to your metrics page, no manual updates needed.

For content creation: Typefully and Hypefury help you schedule and format Twitter threads. Notion or Obsidian for keeping a founder journal you can pull posts from.

For visual updates: Simple tools like Canva or even screenshots from your dashboard work fine. You don't need fancy graphics. Founders trust raw screenshots more than polished graphics anyway.

For community: Indie Hackers, WIP.co, and Makerlog are purpose-built spaces where founders share progress. Worth creating a profile and posting your updates there alongside social media.

Real Examples of Founders Who Did This Well

One founder I know built a simple invoicing tool for freelancers. He posted every single week on Twitter for six months. Not every post went viral. Most got a handful of likes. But by month six, he had 400 followers who were all freelancers, which was exactly his target market. He crossed $5k MRR without running a single ad.

Another founder built a niche project management tool for agencies. She posted on Indie Hackers and LinkedIn regularly, including a brutal post about losing her three biggest clients in one month. That post got shared widely and brought in 40 trial signups in a week. The vulnerability was the marketing.

Neither of these founders had huge audiences before they started. They grew their audience by building in public.

How to Measure If It's Working

Building in public is a long game, so you need to track the right things:

Signups from social: Use UTM parameters on your links to see which platform sends actual signups
Engagement rate: Are people commenting, sharing, saving your posts? That matters more than likes
Follower growth: Slow and steady growth in the right audience is healthy
Backlinks: Use Ahrefs free version or Google Search Console to see if your posts are generating links to your site
Referral traffic: Check your analytics to see how much traffic comes from social platforms and communities
Feedback quality: Are the comments on your posts useful? Are people telling you real things about your product?

If any of these are moving, you're doing it right. Don't expect results in week two. This compounds over months.

Start Small, Start Now

If you're a SaaS founder reading this and haven't started building in public, the best time to start is right now. Not after you hit $1k MRR. Not after you've "figured it out." Now.

Your journey, exactly as messy and uncertain as it is, is valuable to someone else. The founder who's two months behind you needs to hear what you're going through. The potential customer who's on the fence needs to see that you're a real person who cares about what you're building.

You don't need a big audience to begin. You need to begin to build a big audience.

Post your first update this week. Share where you're at. What you're building, why you're building it, and one honest thing about the journey so far. See what happens.

Building in public isn't about going viral. It's about building in the open, one week at a time, and letting people find you as you go.
