From $0 to $10,000/Month
Selling Micro SaaS
The Formula
01 Find a Problem — Search for pain points people pay to solve — recurring, boring, necessary
02 Build with Claude — Describe your SaaS to Claude Code. No coding required. Ship in days.
03 Charge Monthly — Stripe subscription. $20–$99/month. 100 users = $2,000–$9,900 MRR.
The Economics
- $20 Claude/month (your main tool)
- $0–$500 to build V1 (your time only)
- $2,000+ MRR after 100 users @ $20/mo
- 90%+ gross margin (no inventory, no staff)
The barrier to entry is $20/month and the willingness to describe a problem to an AI. The window is open. Most people are still watching.
Step 1 — Find the Right Idea
The mistake most people make: trying to invent something new. The people making money build boring, obvious software that solves a specific problem a specific audience already has.
The Formula That Works
Recurring problem + specific audience + willingness to pay = SaaS idea. You don't need to be creative. You need to be observant.
Where to Find Ideas
| Source | What to Look For | Example Ideas |
|---|---|---|
| Posts starting with 'I hate that...' or 'Why isn't there a tool for...' | Invoice tracker, permit filing helper | |
| Facebook Groups | Questions asked repeatedly in niche groups | Appointment reminder for cleaners |
| Your own job | Tasks you do manually every week | Report generator, data formatter |
| AppSumo | Top-selling lifetime deals — validated by thousands of buyers | Email warm-up, link in bio tool |
| Existing SaaS | Find a $50–$200/mo tool, build the one feature 80% of users actually use for $20/mo | Cut-down CRM, simple invoicer |
The Best Niches Right Now
| Niche | Pain Point | Price Point |
|---|---|---|
| Plumbers / Contractors | No invoicing software that isn't overkill | $29–$49/mo |
| Freelancers | Client portals, contract signing, invoicing | $19–$39/mo |
| Local Restaurants | Reservation + menu + review management | $49–$99/mo |
| Property Managers | Tenant communication, maintenance requests | $29–$79/mo |
| Fitness Coaches | Client check-in, workout delivery, progress tracking | $19–$49/mo |
| Content Creators | Link in bio + analytics + digital product delivery | $9–$29/mo |
| Teachers / Tutors | Assignment tracker, student communication | $9–$19/mo |
Validate Before You Build
- Post in the relevant subreddit: 'Would you pay $X/month for a tool that does Y?'
- DM 10 people in the niche and ask if this problem exists. Don't mention the product yet.
- Search 'I wish there was a tool that...' on Twitter/X. These are free market research.
- Check if the problem has existing competitors. Competitors = validated demand. No competitors = no market.
Step 2 — Build It with Claude
You don't need to know how to code. You need to know how to describe what you want clearly. Claude Code does the rest.
The Stack
| Tool | What It Does | Cost |
|---|---|---|
| Claude Code | Builds and manages your entire codebase from descriptions | $20/mo |
| Cursor | IDE that runs Claude inside your editor | $20/mo |
| Supabase | Database, authentication, and storage | Free tier |
| Stripe | Subscription billing and payments | 2.9% + $0.30 |
| Vercel | Deploy your app live in 60 seconds | Free tier |
| GitHub | Version control — your undo button | Free |
The Build Workflow
- Write a requirements doc — One-page document describing: what the app does, who it's for, the 3 core features, what the data looks like. Give this to Claude before writing a single line of code.
- Build the core first — Start with the single most important feature. Make it work. Don't build onboarding, settings, or dashboards until the core thing works.
- Add auth and database — Tell Claude: 'Implement Supabase auth with email/password login and connect it to the database.' It handles everything.
- Add Stripe subscriptions — Tell Claude: 'Add a Stripe subscription. Users should pay $X/month to access the app.' Claude wires the whole payment flow.
- Deploy to Vercel — Run 'vercel deploy' in your terminal or connect your GitHub repo. Your app is live in under 2 minutes.
- Commit to GitHub after every working feature — Claude can break your app. GitHub is your safety net. Never skip this step.
The Prompt That Builds Your App
You are building a SaaS app for [TARGET USER]. The app does: [CORE FUNCTION IN ONE SENTENCE]
Core features (build in this order):
1. [FEATURE 1 — most important]
2. [FEATURE 2]
3. [FEATURE 3]
Data structure:
{ "user": {...}, "[main_object]": {...} }
Do NOT build onboarding, settings page, or any nice-to-have features yet. Build only the core. Make it work. We'll add features after.
Smaller prompts = better results. Don't try to build everything in one message. One feature per prompt. Review what Claude built before asking for the next thing.
Step 3 — Charge Money (Correctly)
Most vibecoded SaaS products never make money because the builder never sets up billing. Stripe takes 30 minutes with Claude. There's no excuse.
Pricing That Works
The single most important pricing decision: charge monthly, not one-time. A $20/month subscription is worth $240/year. A one-time $50 sale is worth $50 forever. 100 users @ $20/month = $2,000 MRR. That's the target.
| Tier | Price | Who It's For | What's Included |
|---|---|---|---|
| Free | $0 | Hook them in | Core feature, limited usage, no support |
| Starter | $9–$19/mo | Solo users, freelancers | Full access, email support |
| Pro | $29–$49/mo | Small teams, power users | Everything + more usage + priority support |
| Business | $79–$199/mo | Agencies, companies | Unlimited usage + white-label + API |
How to Add Stripe in 3 Prompts
- Prompt 1: 'Add Stripe to my app. Users should be able to subscribe for $X/month. Create a checkout page.'
- Prompt 2: 'After successful payment, mark the user as subscribed in the database and redirect them to the dashboard.'
- Prompt 3: 'Add a webhook that listens for subscription cancellations and updates the user's status.'
Claude handles the Stripe integration, the webhook, the database update, and the redirect. You test it, commit to GitHub, and ship.
The Revenue Math
- $29/mo Average price for a niche SaaS
- 100 users Realistic target month 3–6
- $2,900 MRR at 100 users @ $29/month
- $34,800 ARR (annual run rate)
You don't need 10,000 users. You need 100 people who pay $29/month. That's 100 people in the entire world who have the specific problem your app solves.
Step 4 — Get Your First 100 Users
Building is easy now. Getting users is still the hard part. Here's what actually works for Micro SaaS in the first 90 days.
Phase 1: The First 10 Users (Days 1–14)
Post in subreddits where your target user already exists. Be honest: 'I built this tool to solve X problem. Here's the link. Roast it.'
- Reddit — post in niche subreddits with a genuine 'I built this' post
- Twitter/X — post daily about what you're building. People follow builders.
- Facebook Groups — find groups of your target user, introduce yourself, offer free access
- Cold DM — find 20 people who match your ideal customer, send them a free trial
- Product Hunt — launch there even with 5 users. The community responds to solo builders.
Your first 10 users are the most valuable. Talk to every single one. Ask what they like, what's broken, what they'd pay for. This feedback is worth more than any analytics.
Phase 2: Scale to 100 (Days 15–90)
| Channel | Strategy | Expected Result |
|---|---|---|
| Twitter/X daily posts | Post about the problem, the build process, wins and failures | 200–500 profile visits/week |
| YouTube shorts | 60-second screen recordings: 'I built X in Y minutes with Claude' | 100–1,000 views per video |
| SEO content | Write 3 blog posts targeting '[niche] tool' or '[niche] software' keywords | Organic traffic month 2–3 |
| Partner with creators | Find YouTube/TikTok creators in your niche, offer revenue share | 1,000–10,000 relevant views |
| Cold email | Find email lists of your target user, offer 30-day free trial | 2–5% conversion rate |
The One Thing That Outperforms Everything
Post about the problem your SaaS solves every day on Twitter/X. Not 'buy my product.' Not 'link in bio.' Just the problem. The insight. The pain point your target user feels. The people who feel that pain will find you. That's how you get users who never churn.
Step 5 — Keep Users (The Real Moat)
Acquiring users is expensive. Retaining them is nearly free. A SaaS that keeps its users compounds every month.
| Tactic | What It Does | Impact |
|---|---|---|
| Onboarding flow | Guide new users to their first win in under 5 minutes | Reduces churn by 40% |
| Weekly email | Send one useful tip or new feature every week | Keeps you top of mind |
| In-app feedback | Ask 'What would make this worth 2x the price?' after 7 days | Reveals upgrade features |
| Annual plan discount | Offer 2 months free on annual — collect cash upfront | Reduces monthly churn to 0% |
| Usage notifications | Notify users when they're close to a limit or hit a milestone | Re-engagement |
| NPS after 30 days | Ask 'Would you recommend this?' Score <7: talk to them immediately | Early churn warning |
The Math of Retention
- 5% monthly churn: 100 users → 54 users after 12 months. Treadmill.
- 1% monthly churn: 100 users → 89 users after 12 months. Growth compounding.
Obsess over retention before you obsess over acquisition.
Your 7-Day Action Plan
Stop reading. Start building. Here's exactly what to do.
Day 1 — Find the Idea
Spend 2 hours on Reddit finding a problem. Write down 3 ideas. Pick the one where people are actively asking for a solution.
Day 2 — Validate
Post in the relevant subreddit. DM 5 people. Ask if they'd pay $20/month for a tool that solves this. Get 3 yeses before building.
Day 3 — Write Requirements
One page: what it does, the 3 core features, the data structure. Give this to Claude before touching code.
Day 4 — Build Core Feature
Use Claude Code + Cursor. Build only the core. Make it work. Don't touch design or onboarding yet.
Day 5 — Add Auth + Payments
Tell Claude to add Supabase auth and Stripe subscriptions. Price: $19/month. Test the checkout flow on your own card.
Day 6 — Deploy + Share
Deploy to Vercel. Share the link in 3 relevant subreddits with a 'built this in 3 days' post. Offer free access to first 10 users.
Day 7 — Talk to Your Users
Message every person who signed up. Ask what's broken and what they'd pay more for. Fix the biggest issue. Push the update.
