For decades, startups operated in secrecy.

Founders worked quietly for months—or years—before revealing their product on launch day. Investors saw pitch decks. Users saw marketing pages. The real story of how the company was built remained hidden.

That model is breaking.

A new movement—building in public—is transforming how startups grow, how audiences engage with founders, and how investors discover opportunities.

And it’s happening fast.

The Rapid Rise of “Building in Public”

“Building in public” refers to founders openly sharing their startup journey in real time: product updates, revenue numbers, mistakes, pivots, and lessons learned.

Instead of building silently, founders document the process across platforms like X (Twitter), LinkedIn, blogs, and communities.

The result is a massive shift in how startups grow and launch.

Studies tracking dozens of founders show that startups building in public dramatically outperform traditional stealth launches. One analysis found that startups documenting their progress publicly reached launch audiences and signups far faster, often generating thousands of waitlist users before launch and cutting early customer acquisition costs by roughly 60% compared to traditional marketing approaches.

Another analysis of founders building audiences while developing their product found that about 34% of launch-day users came directly from the audience they built during development, turning content into built-in distribution.

In other words:

Build in public → build an audience → launch into distribution.

This simple loop is why the movement is exploding.

Why People Love Watching Startups Build in Public

At its core, building in public works because it makes startups human.

Traditional startup content looks like polished marketing:
press releases, PR announcements, carefully crafted pitch decks.

But real startup journeys are messy.

Building in public shows the reality:

• Failed product experiments
• Tough hiring decisions
• Feature debates
• Revenue milestones
• Near-death pivots

Transparency builds trust.

Audiences connect with founders who openly share both wins and struggles because the process becomes relatable and authentic rather than corporate.

The psychology is simple:

Humans follow stories.

When a founder documents the journey—from idea to product to traction—followers become emotionally invested in the outcome.

They aren’t just watching a startup.

They’re part of the journey.

This creates powerful network effects:

• Communities form around the product
• Early users become advocates
• Feedback improves the product
• Distribution grows organically

Founder-led storytelling also drives significantly higher engagement than traditional corporate messaging, with some research showing founder content generating up to 8× more engagement than brand accounts.

In short:

People don’t follow companies.

They follow builders.

Investors Are Paying Attention

The rise of building in public has also changed how investors discover startups.

Traditionally, venture capital relied on:

• Warm introductions
• Exclusive networks
• Closed pitch meetings

But today, investors increasingly watch founders online.

Public founder content provides real-time signals about the quality of a startup:

• Speed of product iteration
• Community engagement
• Early traction
• Founder thinking

Transparency around metrics—such as revenue dashboards, user growth, and product updates—can reduce friction during due diligence and give investors early insight into a startup’s momentum.

Instead of relying purely on pitch decks, investors can observe founders actually building.

This shift is creating a new discovery layer for venture capital.

Investors are no longer just sourcing deals through networks.

They are discovering companies through content.

The Problem: The Signal Is Fragmented

Despite the explosive growth of building in public, the ecosystem is fragmented.

Startup progress is scattered across the internet:

• X threads
• LinkedIn posts
• blog updates
• product demos
• random metrics screenshots

Investors who want to follow founders building in public must manually track dozens—or hundreds—of creators across platforms.

Important signals get buried in timelines.

Great founders go unnoticed.

And discovery remains inefficient.

Enter FishTank

FishTank turns building in public into an investing feed.

Instead of scattered posts across social platforms, FishTank aggregates startup progress into a structured environment designed for investors and founders.

Founders can:

• Share progress updates
• post traction metrics
• show product development
• document milestones and pivots

Investors can:

• discover startups early
• watch founders build over time
• evaluate traction signals before fundraising

This creates something that has never really existed before:

A live feed of startups being built.

Not pitch decks.

Not cold outreach.

Actual progress.

Why FishTank Is So Powerful

FishTank works because it aligns with how startups actually evolve today.

Three major shifts are happening simultaneously:

1. Founders are becoming creators

Modern founders produce content constantly.

The founder brand is becoming part of the startup’s distribution strategy.

2. Investors are becoming audiences

VCs increasingly follow founders online to identify emerging companies earlier.

3. Startup discovery is moving to feeds

Just as social media turned information into streams, startup discovery is becoming feed-driven.

FishTank connects these trends.

Instead of passive social content, it creates structured startup discovery.

Investors can scroll and immediately see:

• new startups forming
• traction signals
• founder momentum
• community engagement

It’s the equivalent of a real-time startup market.

The Future of Startup Discovery

Building in public is not a temporary trend.

It’s a structural shift.

Founders want transparency because it builds trust.

Audiences want transparency because it feels real.

Investors want transparency because it reveals traction early.

FishTank sits at the intersection of all three.

It transforms the chaos of public founder content into a single place where startups can build openly and get discovered early.

In a world where founders are already building in public, the logical next step is obvious:

A platform designed for watching startups being built—and investing in them while they grow.

That platform is FishTank.
