Vibe Coder Startup — Build Micro-SaaS Apps. Sell Them on Repeat.
Now accepting founding members

Build micro-SaaS apps for businesses.
Sell them on repeat.

Small businesses are overpaying for bloated SaaS tools and only using 30–40% of the features. You need a niche, a laptop, and the system we'll hand you.

28 daysto your first deployed app
Zerocoding experience needed
$2K–$10K+monthly per niche app

Businesses are paying for software they barely use.

Most small businesses are locked into $200–$500/month SaaS subscriptions and only getting real value from about a third of the features. That gap is where you come in.

Overpaying for 30% of value

They're paying for a bloated platform built for everyone. You build only what matters.

Features they want don't exist

Every niche has 3–5 features that big SaaS companies will never build. That's your product.

You're the expert

You understand the niche because you've lived it. That means you build something more useful than what's out there.

Lean apps that replace bloated software.

Every one of these niches has businesses paying too much for tools that don't fit.

Class Revenue Optimizer

Fill rates, instructor cost vs. revenue, alerts

Fitness studios

Studios pay $200+/mo for platforms they barely use.

Service Agreement Tracker

Recurring contracts, seasonal scheduling, reminders

HVAC companies

Field service software costs a fortune.

Crew & Job Profitability

Daily crew assignment, job-level costs, profitability

Landscape businesses

Generic tools can't tell them which accounts make money.

Membership & Upsell Manager

Subscription tiers, package tracking, upsell prompts

Auto detailing

Generic booking tools don't support memberships.

Cash Flow Forecaster

13-week projections, AR/AP aging, scenarios

Fractional CFOs

Enterprise tools cost thousands and are overkill.

And your niche?

Every industry has businesses overpaying for software that wasn't built for them.

From zero to shipping apps in 28 days flat.

We don't teach you to code. We teach you to build and sell.

Entrepreneur, your guide through this

I've built and sold a startup with a seven-figure exit, sold millions in SaaS software, and spent years as a CPA and CFO. Now I help people take what they know about a niche and build a real lifestyle business around it.

7-figure exit Millions sold in SaaS Former CFO Vibe coding builder

Built for builders who want a real business, not a hobby.

Great fit

  • Business experience or domain knowledge in a niche with terrible software
  • Freelancer, consultant, or coach who wants recurring revenue
  • You've thought "I could build something better"
  • You want a lifestyle business with real margins

Not the right fit

  • Looking for a get-rich-quick scheme
  • Want to learn coding as a career skill
  • Not willing to put in 5–10 hours a week
  • No interest in working with small businesses

Stack niches. Stack revenue.

Build one app for a niche, price it below the bloated tool, and sell it to every business like it.

I'm not a tech guy teaching you AI.
I'm a business guy who figured this out.

I've exited companies, sold millions in SaaS, and spent years as a CPA and CFO. Most AI advice comes from people who've never run a business. This challenge is different — it's built by someone who has.

Chris Jarski — Why I built this challenge

Here's exactly what you'll do each day.

Each day is a self-contained lesson + action step. By the end, you'll have a working app and a plan to sell it.

Day 1

Find your niche & validate the pain

I'll give you the same niche selection framework I use with my private clients. You'll identify a business type where owners are bleeding money on bloated software — and confirm the demand before you build anything.

~30 min
Day 2

Spec it like a product person

You don't need to be technical. You need to think clearly. I'll hand you the exact PRD template I've used to spec apps that generated real revenue — and show you how to fill it out for your niche.

~30 min
Day 3

Build the core app with AI

This is where it gets fun. Using tested prompt workflows and AI tools, you'll build a real, working app. If you can copy and paste, you can do this. I'll walk you through every keystroke.

~45 min
Day 4

Deploy it live

Your app goes from your laptop to a real URL that anyone can visit. One-click deploy. I'll show you the exact setup I use — no DevOps, no server management, no headaches.

~30 min
Day 5

Land your first paying clients

This is where most people get stuck, and it's where my background actually matters. I'll give you the outreach playbook I've used to sell millions in SaaS — adapted for solo builders going after their first 3–5 businesses. You'll know exactly what to say, where to find them, and how to set up recurring billing.

~30 min

Most AI advice comes from people who've never made payroll.

Founder, Vibe Coder Startup

I've built and sold a startup with a seven-figure exit. I've sold millions in SaaS software. I spent years as a CPA and CFO helping businesses figure out what's actually working and what's just burning cash. I'm not a tech influencer — I'm a business operator who figured out how to use AI coding tools to build real software that businesses pay for monthly. This challenge is me pulling back the curtain on exactly how I do it.

Got questions? Good.

Is this actually free?

Yes. 100% free, no credit card. I do have something for people who want to go deeper after the challenge, but the 5 days cost you nothing except your time.

Do I need any coding experience?

Not even a little. If you can copy and paste, you can do this. I designed the challenge for business operators, not developers.

Do I have to show up live?

No. You'll get an email each morning with your challenge. Go at your own pace. Everything stays available throughout the challenge window.

How much time per day?

About 30 minutes. Day 3 might take a bit longer if you get into it, but 30 minutes is enough to complete each challenge.

Will I actually have a working app?

Yes. A real, deployed app with a live URL. Not a mockup — a working piece of software you can demo to potential clients on Day 5.

What tools do I need?

A laptop and internet. I'll walk you through setting up every tool on Day 1. Most have free tiers that are more than enough.

5 days. 30 minutes each.
Your first app, shipped.

I've spent 15 years building and selling software. Let me save you the trial and error.
