The Power of 'Building in Public' for Startup Growth

Let's cut to the chase. You're a founder. You're obsessed with your product, your code is clean, and your architecture is scalable. But you have a nagging fear that keeps you up at night: building a great product is only half the battle. How do you get people to actually find it, use it, and pay for it?

You've probably heard the term 'Building in Public' (BiP). Maybe you've seen founders tweet their MRR graphs and dismissed it as performative vanity. That's a mistake. Building in Public isn't just about sharing your wins; it's one of the most powerful, low-cost growth flywheels available to an early-stage B2B SaaS startup. It’s a strategic framework for building your product, your community, and your brand all at once, using transparency as your fuel.

This isn't a theoretical essay. This is a playbook. We're going to break down what BiP actually is, why it works, and how you can implement it without it becoming a time-sucking distraction from your real job: building a great company.

What 'Building in Public' Actually Means (And What It Isn't)

First, let's clear up the biggest misconception. Building in Public is not just about broadcasting your revenue metrics. While transparency around numbers can be a part of it, it's not the core principle. At its heart, BiP is about sharing the journey—the process, the struggles, the learnings, the pivots, and the victories.

Beyond the Vanity Metrics

Think of your startup's journey as a story. Most companies only show the world the final, polished chapter. Building in Public is about showing the messy first draft, the edits, the parts you crossed out, and the moments of inspiration. It’s about sharing:

• The bug that took your team two days to squash.

• The customer feedback that made you completely rethink a feature.

• The A/B test on your landing page that failed spectacularly.

• The small, unscalable things you're doing to delight your first ten customers.

This isn't a highlight reel. It's the director's cut, complete with commentary. You're not just selling a product; you're inviting people into your world to see how the sausage gets made.

The Four Pillars of Building in Public

To make it actionable, think of BiP as resting on four key pillars:

1. Transparency: This is the foundation. It means sharing the good, the bad, and the ugly. It's about opening up your process, your decision-making, and even your mistakes. This builds trust faster than any marketing campaign ever could.

2. Vulnerability: This is transparency with a human element. It's admitting you don't have all the answers. It's asking your audience for help or advice. This transforms your audience from passive consumers into active participants.

3. Community: You're not broadcasting to a void; you're cultivating a group of people who are invested in your success. They become your earliest adopters, your most vocal evangelists, and your most valuable source of feedback. They are your co-builders.

4. Storytelling: This is how you tie it all together. It's the act of weaving the daily grind—the code commits, the customer calls, the team meetings—into a compelling narrative that people want to follow.

The Tangible Benefits for B2B SaaS Founders

Okay, this all sounds nice. But you're a founder. You care about ROI. You need to know how this translates into tangible business outcomes. Let's talk brass tacks.

De-Risking Your Product Roadmap

As a technical founder, your most valuable resource is engineering time. Every feature you build that nobody wants is a catastrophic waste of that resource. Building in Public is the ultimate antidote. It creates a continuous, real-time feedback loop.

Instead of spending six weeks building a new feature in a vacuum, you can:

• Tweet a problem: "We're noticing our users struggle with X. Is this a real pain point for you?"

• Share a wireframe: "Here's a quick mockup of a potential solution to X. What are we missing?"

• Post a short Loom video: "Walking through the alpha version of our new reporting dashboard. What data would you want to see here?"

You get instant validation or invalidation before a single line of production code is written. This isn't just product research; it's a public co-creation process that ensures you're building what the market actually needs.

Building an Unfair Distribution Advantage

Customer acquisition is the great killer of startups. You can have the best product in the world, but if you can't get it in front of the right people, you're dead. Building in public is a way to build your distribution channel before you even have a product to distribute.

By sharing your journey, you attract an audience of people who are your ideal customer profile (ICP). They follow you because they have the problem you're trying to solve. When you're ready to launch, you're not starting from zero. You have a built-in waitlist of hundreds or thousands of warm leads who already trust you, understand your value proposition, and are eager to try your product. This is your beachhead market, handed to you on a silver platter.

The Ultimate Moat: Community

Let's be blunt: a competitor can copy your features. They can undercut you on price. They can outspend you on Google Ads. But they cannot copy the community you build. A loyal, engaged community that feels a sense of ownership over your product is the most durable competitive moat you can create.

When you build in public, your first users aren't just customers; they're founding members. They report bugs with a sense of shared purpose, not frustration. They defend you on social media. They refer other customers because they are personally invested in your success. This is a level of brand loyalty that money can't buy.

Attracting Talent and Investors

Great engineers and product people don't want to be cogs in a machine. They want to work on interesting problems with authentic, mission-driven leaders. Building in public is your greatest recruiting tool. It's a living resume that showcases your vision, your culture, and your resilience.

Similarly, investors aren't just betting on an idea; they're betting on a founder. Your public journey provides them with months of due diligence material. They can see how you handle adversity, how you listen to customers, and how you build momentum. A founder with a dedicated community and a validated product roadmap is a dramatically de-risked investment.

A Practical Playbook: How to Build in Public Without Wasting Your Time

This is where the rubber meets the road. You're busy. You don't have time for another 'marketing thing.' The key is to integrate BiP into your existing workflow, not add it on top.

Step 1: Choose Your Stage and Your Channel

Don't try to be everywhere at once. Pick one primary channel and own it. For most B2B SaaS founders, the best options are:

• Twitter/X: Best for short-form, real-time updates, quick questions, and engaging with other builders. The tech and startup ecosystem lives here.

• LinkedIn: Better for more polished, professional insights, case studies, and reaching decision-makers in specific industries.

• A Personal Blog/Newsletter: Ideal for long-form, deep-dive content where you can explore complex topics and build a direct relationship with your audience via email.

Start with one. Once you've built a habit and a following, you can repurpose content for other channels.

Step 2: Create a Content Cadence (The Founder's "Content API")

Don't wait for inspiration to strike. Systematize it. Think of it as an API for your brain. Create a simple, repeatable weekly schedule. It doesn't need to be complicated. For example:

• Monday: Share your main goal for the week. (e.g., "This week, we're focused on squashing the auth bug and onboarding our next three beta users.")

• Tuesday: Post a screenshot or a short video of something you're working on. Ask for feedback.

• Wednesday: Write a short thread summarizing a key insight from a customer conversation or a book you're reading.

• Thursday: Share a small win or a surprising metric. (e.g., "Wow, our new landing page has a 10% conversion rate! Here's what we changed.")

• Friday: Post a weekly review—what went well, what didn't, and what you learned.

This simple structure removes the daily anxiety of "what should I post?" and turns content creation into a low-friction habit.

Step 3: What to Share? Your "Commit Log" of Progress

Treat your public feed like a

git commit

• Product: Post wireframes, feature debates (

  ), roadmap questions, and bug reports.

• Growth: Share your churn numbers, a cold email template that's working, a failed ad campaign, or your traffic from a specific channel.

• Learnings: Talk about a mistake you made in hiring, a mental model that helped you solve a problem, or a key takeaway from a podcast.

• The Story: Don't forget the human element. Share why you started this company. Talk about a moment of doubt or a conversation that re-energized you.

Step 4: Engage, Don't Just Broadcast

This is the most critical step. Building in Public is a dialogue, not a monologue. Spend 15-30 minutes a day not just posting, but engaging.

• Reply to every single comment. Acknowledge the feedback, thank people for their input, and answer their questions.

• Ask questions. Use your audience as a brain trust.

• Amplify others. Retweet other founders, praise products you admire, and share content from people in your space. A rising tide lifts all boats.

The Hard Parts: Common Pitfalls and How to Avoid Them

Building in Public isn't without its challenges. Here's how to navigate the common roadblocks.

The Fear of "Giving Away Your Ideas"

This is the most common fear and the most misplaced. Your idea is not your moat. A vague idea on Twitter is worthless. Your value is in your unique execution, your team's talent, your insights, and the community you build. The feedback you'll get from sharing your idea publicly is infinitely more valuable than the infinitesimal risk of someone with the exact same skills, passion, and resources deciding to drop everything to copy you.

Dealing with Negativity and Trolls

It will happen. The internet has trolls. The key is to not let it derail you. Use a simple framework: 99% of negative feedback should be ignored and blocked. For the 1% that is good-faith, constructive criticism, engage with it publicly. Thank them for their perspective. It shows you're open-minded and builds even more trust with your real community, who will often come to your defense anyway.

The Time Suck Fallacy

Founders often say, "I don't have time for this." Reframe it. You're not adding a new task; you're documenting the tasks you're already doing. It's product research, marketing, and recruiting rolled into one. It should take you no more than 30 minutes a day if you follow a system. That said, as you scale, documenting and strategizing can feel like a full-time job. Many founders realize that while they can lead the narrative, they need support executing the marketing mechanics. For those who are too deep in product to run this playbook consistently, a done-for-you service that handles the execution while you provide the raw insights is often the highest-leverage investment. That's precisely why we built AgentWeb, to act as that outsourced marketing engine.

The "I Have Nothing to Share" Mindset

This is classic imposter syndrome. You feel like your daily work is boring and no one would care. You're wrong. The bug you just fixed is a lesson in debugging for another engineer. The tough customer call you just had is a lesson in sales for another founder. Your journey, in all its mundane detail, is the content. Your progress is the story. People don't follow you for polished perfection; they follow you for the relatable, authentic struggle and the incremental wins.

Case Studies: Founders Who Nailed It

Still not convinced? Look at the giants who used this playbook to build iconic companies.

Gumroad & Sahil Lavingia

Sahil is arguably the godfather of the modern BiP movement. He shares everything: his company's full financials in public, his board meeting notes, his investment memos. This radical transparency didn't just build a product; it started a movement. Creators flocked to Gumroad because they trusted Sahil and the company's ethos. That trust is a brand asset that is nearly impossible to replicate.

Buffer & Joel Gascoigne

Buffer pioneered transparency in a different way, most famously with their open salaries formula. They shared their revenue, equity structure, and fundraising details long before it was popular. The result? They built an incredible employer brand that attracted top-tier, value-aligned talent from all over the world. Their transparency became their biggest marketing asset and a core part of their product's identity.

Levels & Sam Corcos

Levels, a health-tech company, takes BiP to an operational extreme. They document nearly everything in public-facing Notion documents—from their company culture and hiring process to their product specs and engineering principles. This has created a cult-like following among tech's A-players and has made recruiting their superpower. They attract the best because the best can see exactly how the company thinks and operates before they even apply.

Building in Public is a long-term game. It's a compound-interest strategy for growth. It won't deliver a thousand new users overnight. But it will, slowly and surely, build you a resilient company with a built-in audience, a de-risked product, and a brand that people genuinely care about. It's the most authentic marketing you'll ever do, because it's not marketing—it's just the story of you, building.
