Ship & Sell Starter Kit
You can build anything.
But nobody's buying.
The engineer's system for getting your first paid customer - even if you've never written a marketing word in your life. Built by a Staff Engineer who spent years shipping great software and zero time selling it.
- ✓Stop Googling "how to launch." A 47-point checklist replaces the 47 contradicting blog posts you have open right now.
- ✓Your AI becomes your co-founder. Set up Claude or ChatGPT as a launch partner that knows YOUR product, audience, and voice.
- ✓Real numbers, real playbook. Built by an engineer who ran a Udemy course to 3,000+ paid students - at 1 hour a day.
Early-access pricing. $29 while the first 50 launches land.
You shipped. They didn't come.
You're a developer. You used Claude or Cursor to vibe-code a full SaaS in three weekends. The code works. The deploy is clean. The landing page has a checkout button.
Then... crickets.
- • Zero users. Zero revenue.
- • You post on Reddit - removed. On X - two likes from bots.
- • You Google "how to launch" and get 47 contradicting blog posts, 40 of them written by people selling $299 courses.
- • You have no idea what to write on a landing page, what to email your 12 subscribers, or where your actual buyers hang out.
The problem isn't your product. It's that nobody taught engineers how to sell.
Why this is possible now
Three things shifted recently.
AI carries the entire marketing-copy layer - if you feed it context.
Headlines, emails, Reddit posts, cold DMs. Most devs skip the "feed it context" part and wonder why the output is generic. The ones who set it up properly ship launches in days.
Platform barriers dropped to zero.
Lemon Squeezy, Gumroad, Stripe Payment Links - you can take a payment in 30 minutes from scratch.
The solo dev playbook is real.
Marc Lou ($94K+/month at ShipFast), Pieter Levels ($5M+ ARR solo), Danny Postma ($300K/month peak) - all publicly self-reported. They're not unicorns - they're devs who learned the 5 things engineering school doesn't teach.
You already know the hard part: how to build. The kit handles the other half.
Case study
Real devs who figured it out
Sebastian Wilgosz - 3,000+ paid students, Rails API course, zero marketing background
3,000+ Udemy course sales · Hanami Mastery 2021-present
I ran a Rails API course to 3,000+ paid students as a side project, at 1 hour a day, after the kids went to bed. I shipped Hanami Mastery as a one-person open-source education site and kept it running for 5+ years, growing it from $0 to $1,700/month.
This kit is the system I wish someone had handed me when I was at $0 with a coded-but-unsold product.
Benefits
What changes after you buy
Stop Googling, start doing.
A single 47-point checklist replaces the 100 tabs you have open about "how to launch." Days 1-3 setup. Days 4-14 launch and distribute. Copy it, check it off.
Your AI becomes your co-founder.
Set up a personal launch agent (Claude or ChatGPT) that knows YOUR product, YOUR audience, and YOUR voice. Every future prompt - landing page copy, Reddit post, cold DM, email - runs with full context. No more "write me a Reddit post about my product" producing generic mush.
Real playbook, real numbers.
Built from real launches, not theory: a Rails API course grown to 3,000+ paid students on Udemy, and Hanami Mastery, grown from $0 to $1,700/month. The wins and the flops are baked into the checklist and prompts.
Launch in 14 days, not "someday."
Day-by-day steps. No ambiguity, no filler. You'll know exactly what to do each morning before you open your IDE.

About
Who made this
Hi, I'm Sebastian Wilgosz. Staff Software Engineer. Wrocław, Poland. Three kids, one side project at a time.
What I've actually shipped:
- Hanami Mastery - open-source education site for the Hanami Ruby framework, 2021-present
- A Rails API course on Udemy with 3,000+ paid students - run entirely as a side project, at 1 hour a day
- automateideasai.com - AI idea-validation tool, live with paid checkout
- Architect of event-driven systems at a Singapore-based data engineering contract for 5+ years
What I'm NOT:
- A YouTube guru
- A "passive income" salesman
- A full-time marketer
I write code for a living and ship products the way engineers ship software - with systems, retros, and real numbers. This kit is my system, extracted and packaged so you don't have to spend 4 years figuring it out solo. This is v1 - I'm the first case study.

FAQ
Questions, answered
Who is this for?+
Developers who built something - a SaaS, a tool, an app - but have zero or near-zero sales. You can code. You need a system for everything that comes after `git push`. It's NOT for someone who hasn't shipped anything yet; go build a 2-week MVP first.
I have no audience and no followers. Will this work?+
Yes. This system was built from zero audience. The checklist includes specific outreach steps (niche subreddits, IH, cold DMs with a template) that don't require an existing following.
What format are the deliverables?+
Markdown files - AI-first by design: paste them into Claude, ChatGPT, or Gemini, or point Cursor / Claude Code at the folder. The launch checklist also comes as a Google Doc you can copy and check off. No logins, no apps, no subscriptions. One shared Google Drive folder, instant access.
How is this different from Marc Lou's ShipFast or Rob Walling's SaaS Launchpad?+
ShipFast is ~$300 and ships CODE (Next.js boilerplate). SaaS Launchpad is ~$500 and is a video course. This kit is $29 and ships the "everything AFTER you've shipped" layer - landing page copy, emails, Reddit posts, the AI context setup. If you want boilerplate code, buy ShipFast. If you want a video course, buy Walling. If you want a no-fluff executable system for $29 - start here.
What if it doesn't work?+
Follow the system. Launch in 14 days or money back. No questions, no hoops. I'd rather refund you than have someone feel ripped off.
Is this another guru course?+
No videos. No webinars. No "masterclass." The kit is complete - not a teaser for a $997 program. Just a checklist, templates, and AI prompts - built by a working engineer. If you've been burned by a wealth guru before, this is the opposite of that.
Do I need to know marketing?+
No. The AI prompts generate your copy, outreach messages, and posts. You provide context about your product; the system does the heavy lifting. You're an engineer - you already know how to fill out a YAML file. Same idea.
Will this work for a SaaS / info product / desktop app / API?+
The kit is product-type-agnostic. The prompts ask what you shipped and adapt accordingly. It won't help you sell enterprise B2B contracts - that's a different game - but for $29/mo SaaS, one-time tools, info products, and indie apps, the playbook holds.
The next 14 days
Your first paying customer, within 14 days.
Two weeks from today, you could have a launched product, a working checkout URL, and a system that runs every future launch on autopilot.
Or you could spend two more months reading contradicting blog posts from people selling $299 courses.
14-day money-back guarantee · Instant download · No account
PS - The guarantee is simple: follow the system, launch in 14 days. If it doesn't happen, email the word "refund" and it's done. No questions, no hoop-jumping. I built this for engineers & builders, not for chargebacks.
