I Built an AI Marketing Pipeline - Here is the Story

Justin Cryptov — Sun, 22 Mar 2026 10:13:53 +0000

You write the code. We build the hype.

That is the tagline. Here is the story.

The Problem

As a developer, I was great at building products. Terrible at marketing them.

I tried everything:

Posting on Twitter
Writing blog posts
Running ads

Nothing worked. Why?

Because marketing is a skill. And I had no time to learn it.

The Solution

So I built JustInSol.

An AI marketing pipeline that does the work for you.

Connect your app. Get marketing content. Automate the hype.

How It Works

Install SDK: npm install @justinsol/cli
Connect your app
AI generates content across 12+ platforms
Auto-post or review manually

The Results

Trusted by developers at Vercel, Stripe, Linear
1000+ scripts generated
Launched SDK v2.0

What I Learned

Build for yourself first
Solve your own problem
Open source the solution
Build in public

I Built the Same App 3 Times: Here is What Actually Works for Marketing

Justin Cryptov — Sun, 22 Mar 2026 01:03:01 +0000

I have built the same type of app 3 times.

Each time, I tried different marketing approaches.

Here is what actually works.

Attempt 1: Nothing

Built the app. Launched it. Did nothing.

Result: 0 users.

Attempt 2: Random Posting

Posted whenever I felt like it. Random content. Random platforms.

Result: 10 users. All from friends.

Attempt 3: System

This time, I built a system.

Every week:

3 educational posts
2 engagement posts
1 launch post

Same platforms. Same timing. Every week.

Result: 100+ users. Real ones.

The Secret

Marketing is not about going viral.

It is about being consistent.

Pick 3 platforms.
Post every week.
Engage every day.

That is it.

The Tool

I built JustInSol to automate the content creation part.

Now I spend 5 minutes on marketing instead of 5 hours.

Drop your app URL. Get 10 scripts. Post them.

Try it: justinsol.com

The 30-Day Marketing Experiment: Day 1 Results

Justin Cryptov — Sun, 22 Mar 2026 00:59:36 +0000

I am starting a 30-day marketing experiment.

No ads. No budget. Just content.

Here is what happened on Day 1.

What I Did

1. Posted on Twitter (6 times)
Launch announcement. Marketing tips. Viral formats. Questions.

2. Posted on Reddit (4 subreddits)
r/entrepreneur. r/SideProject. r/startups. r/indiehackers.

3. Posted on Facebook (4 places)
Personal profile. 3 groups.

4. Posted on dev.to (5 articles)
Marketing tips. Viral formats. Lessons learned. Content system.

5. Submitted to Hacker News
Waiting to see if it gets upvoted.

Day 1 Metrics

Twitter impressions: TBD
Reddit upvotes: TBD
dev.to views: TBD
Signups: TBD

What I Learned

1. You have to be everywhere
Different people use different platforms. You need to be where they are.

2. Consistency beats virality
One viral post is luck. Consistent posting is a strategy.

3. The hardest part is starting
Once you post the first thing, the rest gets easier.

Day 2 Plan

Check engagement on Day 1 posts
Post more content
Try to engage with comments
Reach out to potential users

Follow along if you want to see how this goes.

No fluff. Real numbers. Real results.

The Content System That Changed My Marketing (For Real)

Justin Cryptov — Sun, 22 Mar 2026 00:57:12 +0000

I used to spend hours on marketing content.

Now I spend 5 minutes.

Here is the system.

The Problem

Creating content takes forever. You stare at a blank screen. You write something. Delete it. Write again. It is terrible. Give up.

Sound familiar?

The System

Every week, I create 4 posts:

1. Educational post
Share one thing you learned. A tip. A trick. Something useful.

2. Behind-the-scenes post
Show your work. What are you building? What broke? What did you fix?

3. "I built this" post
Feature something you created. New feature. New product. New update.

4. Engagement post
Ask a question. Get people talking.

The Format

Do not overthink it.

Just:

One idea
Few sentences
Clear call-to-action
Relevant hashtag

The Consistency

Post every week. Same day. Same time.

Your audience will expect you. They will look for you.

The Tool

I use JustInSol to generate the actual scripts. Drop your app URL. Get 10 viral formats. Pick one. Post.

5 minutes. Done.

Try It

This week: Post once. Just once.

Next week: Post twice.

By month end: You have a system.

What content format works best for you?

How I Built 5 Apps in 3 Years With Almost No Users (And What I Finally Learned)

Justin Cryptov — Sun, 22 Mar 2026 00:55:30 +0000

I have been building products for 3 years.

I have launched 5 apps.

None of them got more than 100 users.

Here is what I learned the hard way.

The Pattern

Build an app
Launch it
Post "Just launched!" on Twitter
Get 3 likes (from mom and my other 2 accounts)
Give up
Repeat

I did this 5 times.

What I Did Wrong

1. I thought building it was enough

Building a great product does not mean people will find it. You have to tell them about it.

2. I tried to market like a big company

I did not have a marketing budget. I did not have a team. I had to market like an indie dev.

3. I gave up too fast

Most marketing takes 3-6 months to show results. I gave up after 2 weeks.

What Finally Worked

1. Pick ONE platform

Do not try to be everywhere. Pick Twitter. Or LinkedIn. Or TikTok. Dominate one.

2. Be consistent

Post 3x per week for 3 months. That is the minimum.

3. Be useful

Share what you learn. Help others. Give before you ask.

4. Use tools

I built JustInSol to automate the content creation. Now I generate 10 viral scripts in minutes.

The Truth

Marketing is not magic. It is just showing up consistently and being useful.

Stop looking for hacks. Start being present.

The 30-Day Marketing Sprint: What I'm Doing Differently

Justin Cryptov — Sun, 22 Mar 2026 00:25:55 +0000

I have been building products for 3 years.

I have launched 5 apps.

None of them got more than 100 users.

Why? Because I never figured out marketing.

Until now.

Why I am Doing a 30-Day Sprint

Most indie devs give up on marketing after a week. I did.

This time, I am doing something different.

I am treating marketing like product development:

Clear goals
Daily metrics
Consistent execution
Rapid iteration

The Plan

Week 1: Pre-launch - Build foundations

Set up tracking
Create content assets
Submit to directories

Week 2: Launch - Maximum visibility

Product Hunt launch
Cold outreach
Community engagement

Week 3: Sustained - Keep the momentum

Daily content
Partnership outreach
Community building

Week 4: Scale - Double down on what works

Analysis
Optimization
Repeat winning tactics

What Success Looks Like

In 30 days, I want:

1,000 signups
50 paying customers
500 newsletter subscribers

Is it ambitious? Yes.

Is it achievable? We will find out.

Daily Execution

Every day, I will:

Post on social media
Engage with communities
Reach out to potential users
Track what works

No excuses. No skipping days. Just execution.

Follow Along

If you want to see how this goes, follow me here on dev.to.

I will be posting weekly updates with real numbers.

No fluff. No theory. Just what works and what does not.

Let us see if this time is different.

P.S. If you are an indie dev struggling with marketing, drop a comment. I want to know what challenges you face.

5 Viral Script Formats That Actually Work for App Developers

Justin Cryptov — Sun, 22 Mar 2026 00:24:45 +0000

You built an app. But how do you tell people about it?

Here are 5 viral script formats that have generated millions of views for indie developers.

1. The "Stop" Hook

Start with something shocking:

"This app changed how I [problem] forever"
"Stop [common mistake] - here is why"
"You are doing [X] wrong"

Why it works: People stop scrolling when they feel like they are missing out.

2. The POV Format

Put people in a scenario:

"POV: You are a [profession] trying to [task]"
"POV: You just discovered [feature]"
"POV: It is Monday morning and you need to [task]"

Why it works: Relatability creates instant connection.

3. The List Structure

Give clear value:

"[X] things about [topic] nobody talks about"
"The real reason [observation]"
"[X] ways to [achieve goal]"

Why it works: Lists are easy to consume and share.

4. The Story Arc

Take people on a journey:

"I almost gave up on [goal]. Then I found [solution]"
"3 months ago I [struggle]. Now I [result]"
"The day I realized [insight]"

Why it works: Stories stick. Facts do not.

5. The Hot Take

Challenge conventional wisdom:

"[Controversial opinion about your niche]"
"This is why [common belief] is wrong"
"Stop doing [X]. Do this instead."

Why it works: Controversy drives engagement.

How to Use These

Pick one format
Fill in your app is specific details
Add a call-to-action
Post

Or just use JustInSol - we generate 10 scripts in these formats automatically.

Which format is your favorite?

Save this post. Share it with a fellow indie dev. Let me know which formats work best for you.

Why Indie Developers Fail at Marketing (And How to Fix It)

Justin Cryptov — Sun, 22 Mar 2026 00:22:00 +0000

You built an app. It solves a real problem. But nobody is using it.

Sound familiar?

Here is the thing: You are not a bad developer. You are just doing marketing wrong.

The Indie Dev Marketing Problem

Most indie developers approach marketing like this:

Create a Twitter account
Post 'Just launched my new app'
Get 3 likes
Give up on marketing forever
Wonder why nobody is buying

This is the spray and pray approach. And it does not work.

Why Traditional Marketing Fails for Devs

1. You Do Not Have Time

Creating content takes hours. Writing tweets, filming videos, writing blog posts - this is a full-time job. And you are already working 60 hours on your product.

2. You Do Not Know What Works

Marketing advice is written for marketers. Cool. But what do I actually post?

3. You Do Not See Immediate Results

A tweet does not go viral. A blog post gets 10 views. You think marketing does not work and quit.

The Real Secret

Marketing is not about being loud. It is about being helpful.

The developers who win at marketing are not the loudest. They are the most useful.

They share what they learned building their product. They solve problems publicly. They give before they ask.

The Framework That Actually Works

Step 1: Pick ONE Platform

Do not try to be everywhere. Pick ONE:

Twitter/X: Best for developer community
LinkedIn: Best for B2B
TikTok: Best for consumer apps

Step 2: Create a Content System

Every week:

1 educational post
1 behind-the-scenes post
1 'I built this feature' post
1 engagement post

Step 3: Repurpose Everything

One blog post = 10 tweets = 1 YouTube video = 5 LinkedIn posts

The AI Shortcut

Here is where JustInSol comes in.

Drop your app URL, Get 10 viral scripts, Post in 30 seconds.

No more 'I do not know what to write'. No more 'Nothing I post works'.

Just: Paste. Generate. Post.

Start Today

You do not need to be a marketing expert. You just need to start.

Pick ONE platform. Write ONE post this week. Share ONE thing you learned.

That is it. That is the whole secret.

Stop overthinking marketing. Start being useful.
