How He Built a $15k/Month App to Quit His 9-5

"My name is Ben, and I turned my side project into a full-time job... It started out as a side project, but I was actually laid off in 2023, and I had to make the decision to either go full-time on my side project or accept a job offer."

This is the story of Ben, a software developer who, after a series of failed side projects, finally built a business that allowed him to leave the 9-to-5 world behind.

1. The $15k/Month Side Project: `Tech Lockdown`

Tech Lockdown is a platform that helps adults block distracting websites and apps to be more intentional with their internet use. It uses a VPN-based approach to filter a user's internet connection across their devices.

The Business Model:

Revenue: Over $15,000 in Monthly Recurring Revenue (MRR).
Customers: 1,300+ paying customers.
Pricing: A 14-day free trial, then either $15/month or a discounted annual plan ($10/month equivalent).

2. The Journey of Failed Projects

Before Tech Lockdown, Ben had a string of unsuccessful side projects:

A Lead Gen Platform: He got obsessed with the logo and colors and didn't think about the business model.
A Landing Page Builder: He overcomplicated it and burned himself out before even launching.
A Web Agency: He co-founded an agency, but found it to be a difficult and stressful business to run.

These failures taught him valuable lessons that he would apply to his next, successful venture.

3. The Turning Point: Solving His Own Problem

The idea for Tech Lockdown came from a personal need. In 2020, with the rise of work-from-home, Ben wanted to set up guardrails for his own internet use and found it incredibly difficult.

Instead of immediately building a product, he changed his approach:

He documented his solution: He distilled his research and personal system into a YouTube video and a Reddit post.
He built an audience first: The content resonated with a huge number of people. He was flooded with messages and emails. For a year, he didn't monetize at all; he just kept creating free, helpful content and building his audience.

"It was actually really helpful to have an audience who was really focused on that topic... I knew that someone would use it eventually. So, it was really motivating."

This was the key difference: he wasn't just building in a vacuum. He had a pre-qualified audience waiting for a solution.

4. The Growth Strategy: Content & Subtle Promotion

Ben's core strategy was creating well-researched, genuinely helpful content and giving it away for free. This made it easy for people to share.

The "Dumb Phone" Guide: He created a detailed, step-by-step guide on how to turn an iPhone into a "dumb phone" with limited app access. This single article has been read hundreds of thousands of times and is a top driver of organic traffic.
The Reddit Method: He learned that you can't be overly promotional on Reddit. His strategy was to put all the valuable information directly in the Reddit post itself, and then subtly tack on a reference to his full guide or YouTube video at the end. This led to more engagement and a higher chance of hitting the front page.

"A big part of it is authenticity. A lot of my competitors are kind of these faceless apps or companies... It helps to just put your face on it and own what you're building."

5. The Tech Stack for a Solo Founder

Ben's tech choices were based on speed and simplicity, perfect for a side project with limited time.

Database & Auth: Supabase.
Web Framework: SvelteKit (more accessible for JavaScript developers).
Hosting: Vercel ($20/month for peace of mind and CI/CD).
Email: Mailgun and Elastic Email.
Analytics: Plausible Analytics ("probably one of the more important optional things that I pay for").

With this lean stack, he estimates you can easily hit a 70% profit margin.

6. Ben's Advice for Side Hustlers

Solve Customer Acquisition First: Before you quit your job, you must have a reliable way to get customers. You need a plan that you can "throw gasoline on" once you have more time.
Don't Start Just to Escape: "It's really not that glamorous being your own boss." If you hate your job, your first priority should be finding a better job, not starting a business out of desperation.
Work on Something You're Passionate About: You need to be genuinely excited about your project to find the motivation to work on it early in the morning or after a long day at your main job.
Don't Overcomplicate the MVP: "Find the simplest version of the product to prove the concept first. Getting bogged down in the details leads to burnout and not actually shipping."
