Build in public

Building in public means sharing your startup's journey -- from metrics and milestones to struggles and lessons -- openly with the world. Instead of building in a silo, you create a narrative that attracts followers, builds trust, and turns an audience into your first customers. It's a marketing flywheel that's authentic, powerful, and costs nothing but your time.

Why Building in Public Works

Building in public taps into the 'IKEA effect' and the principle of reciprocity. When people see the effort, the challenges, and the behind-the-scenes work, they feel more connected to the product and the founder. They've seen it being built, so they value it more. By sharing your journey, you are giving value first -- in the form of lessons, entertainment, or inspiration -- which makes your audience want to give back, either through feedback, sharing, or eventually, purchasing.

This strategy also short-circuits the trust deficit new products face. Every post, every metric shared, every challenge overcome is a small deposit in the bank of trust. It serves as continuous social proof. When a potential customer sees a founder openly sharing their revenue, their user feedback, and their product roadmap, it signals confidence and transparency, reducing the perceived risk of trying or buying a new, unknown product.

Three real examples

SaaS TransparencyFrom $0 to $10M ARR sharing everything

Buffer: Pioneering Radical Transparency

Buffer is a classic example. From day one, they shared everything -- revenue, salaries, equity, and even their diversity numbers. This radical transparency created immense trust and a loyal following. It wasn't just a marketing tactic; it became their core identity and a key differentiator in a crowded market, attracting both customers and talent aligned with their values.

Gumroad: Sahil Lavingia's Public Turnaround

After his venture-backed startup failed to reach unicorn status, founder Sahil Lavingia bought back a majority stake and started building Gumroad in public. He shared his financials, his product decisions, and his philosophy on running a sustainable business. This honest and open journey resonated with creators and entrepreneurs, helping to reboot Gumroad's growth and establish Sahil as a leading voice in the indie founder space.

Levels: Building a Company in Public

Levels, a health tech company focused on metabolic health, has a public-by-default culture. They share internal memos, product strategy documents, and even fundraising updates publicly. This creates an incredible feedback loop with their most engaged users and positions them as an open, trustworthy authority in their field. It shows confidence and allows their community to feel like true insiders.

Your first 100 followers are the hardest to get, but they will be your most valuable source of early feedback and support.

The step-by-step playbook

  1. 1

    Step 1: Choose Your 'Public' Square

    Decide where you'll share your journey. Twitter/X and LinkedIn are the most common for founders. Pick one platform to start and be consistent. Don't try to be everywhere at once. Go where your target audience is.

  2. 2

    Step 2: Define Your Content Pillars

    Decide what you'll share. Good pillars are: 1) Metrics (MRR, users, traffic), 2) Wins (features shipped, new hires), 3) Losses & Lessons (bugs, failed experiments), and 4) Behind-the-Scenes (your process, your 'why').

  3. 3

    Step 3: Set a Realistic Cadence

    Consistency is more important than frequency. A weekly update thread is a great start. Daily posts can work if they are small and authentic. Whatever you choose, put it in your calendar and stick to it for at least 30 days.

  4. 4

    Step 4: Post Your Origin Story

    Start by introducing yourself and your project. Why are you building this? What problem are you solving? This first post sets the stage and gives context for everything that follows. Pin it to your profile if you can.

  5. 5

    Step 5: Document, Don't 'Create'

    Don't overthink it. The easiest way to build in public is to document what you're already doing. Fixed a bug? Share how. Designed a new feature? Post a screenshot. The content is your daily work.

  6. 6

    Step 6: Share Numbers, Not Just Stories

    Numbers are the language of building in public. Share your monthly recurring revenue (MRR), number of users, conversion rates, or even just website traffic. This transparency is what makes the process compelling and builds credibility.

  7. 7

    Step 7: Engage With Everyone

    Building in public is a dialogue, not a monologue. Reply to every comment and question. Thank people for their feedback. This engagement is how you build a community, not just an audience.

The 'Weekly Update & Feedback' Template

Here's a simple template for a weekly update on Twitter/X or LinkedIn. It's designed to share progress and actively solicit feedback.

Another week building {My Product}! Here's a quick update:

- 🔥 Shipped: {A feature or fix you launched}
- 📈 Metric: {e.g., Weekly Active Users} is now at {Number}
- 🤔 Learning: {A lesson you learned this week}

I'm currently working on {Next feature/problem}. Here's a sneak peek (see screenshot/video).

What do you think of {Specific question about the new feature}? Feedback is a gift!

Key Questions for Your 'Build in Public' Strategy

  • What is the unique story behind why I'm building this?
  • Which platform do my ideal customers spend the most time on?
  • What are the 3-5 key metrics that truly define my product's progress?
  • What is my 'red line' -- what information is too sensitive to share publicly?
  • How can I turn my updates into a conversation rather than a broadcast?

The most important questions are about your 'why' and your audience. If you know why you're sharing and who you're sharing it for, the 'what' and 'how' become much easier.

Generate weekly update post

Act as a founder building a {SaaS app for marketers} in public. Write a compelling weekly update post for {Twitter/LinkedIn}. This week's key events were: {we got 10 new users, fixed a major bug in the login flow, and had a great feedback call with a customer named Sarah}. Make it sound authentic and engaging.

Brainstorm content ideas

I am building {a mobile app for hikers} in public. Give me 10 content ideas I can share over the next month. The ideas should fall into these categories: Metrics, Wins, Losses/Lessons, and Behind-the-Scenes.

Turn a feature into a story

I just launched a new feature: '{e.g., AI-powered summary for long documents}'. Help me write a short, compelling story for my blog about *why* we built this feature. Include the problem we saw, the process of building it, and who it's for. The goal is to make the update feel human and problem-oriented, not just a list of technical specs.

Mistakes that kill this play

  • Only sharing the wins. People connect with struggles. Sharing your challenges makes you more relatable and trustworthy.
  • Being inconsistent. Building in public is a flywheel; it needs consistent pushes to get going. Sporadic updates won't build momentum.
  • Broadcasting, not engaging. Don't just post and ghost. The real value is in the conversations and relationships you build in the replies.
  • Forgetting the 'build' part. You must make progress on your product. If you're only tweeting and not shipping, your audience will lose interest.
  • Sharing sensitive information. Know where to draw the line. Don't share customer data, critical security info, or personal details that could put you at risk.
  • Chasing vanity metrics. Focusing on follower counts instead of genuine engagement and feedback leads to hollow results.

Your First 7 Days of Building in Public

  • Day 1: Choose your primary platform (e.g., Twitter/X). Write and post your origin story: who you are, what you're building, and why. Pin it to your profile.
  • Day 2: Share a screenshot or a short video of the current state of your product. Talk about what you're working on right now.
  • Day 3: Share a 'learning'. What's something you figured out this week? It could be a technical discovery, a user insight, or a marketing lesson.
  • Day 4: Post one key metric. It doesn't have to be revenue. It could be '0 signups' or '100 landing page visits'. Be honest.
  • Day 5: Ask a direct question to your audience. For example, 'What's the one feature you wish our product had?' Spend 30 minutes engaging with every reply.
  • Day 6: Share a small win. Did you fix a bug, design a new logo, or get a nice comment? Celebrate it publicly.
  • Day 7: Summarize your week in a short thread. What went well? What didn't? What are you focused on next week? Link to your posts from the week.
