3 SaaS that make millions (you can copy this weekend)
3 Micro-Startups You Can Copy This Weekend
Welcome to Ready to Release!
I'm Victor, and every week I share what I discover while building SaaS from scratch.
Today: 3 ultra-simple tools that generate millions of visits without ads.
Think less, do more. Let's go.
🎨 1. Background Removers (Remove.bg)
Source: SimilarWeb, Octubre 2025
What it solves: Designers, e-commerce businesses, and content creators constantly need to remove image backgrounds. Photoshop is expensive and complex. Free alternatives give mediocre results.
How it works: User uploads image → AI detects and removes background in 3 seconds → Downloads transparent PNG. That's it. No tutorials, no learning curve.
Real-life use cases:
- Online stores removing backgrounds from 500 product photos
- Designers cleaning up logos for clients
- Content creators preparing YouTube thumbnails
- Freelancers retouching professional CV photos
The numbers:
- 73.3M visits/month
- 51.2% free organic traffic
- 43,100 keywords ranking
The magic keyword: "remove bg" → 3.78M searches/month
The growth hack: They don't just rank for "background remover." They create specific pages for each use case:
/remove-signature-background→ For scanned signatures/remove-logo-background→ For cleaning up logos/transparent-background→ For PNGs/remove-photo-background→ For portraits
Each page ranks independently on Google. Scalable to 100+ pages = 100+ streams of organic traffic.
Stack: Next.js + Remove.bg API or Replicate (open-source models) + Vercel Time: 2-3 days Monetization: Freemium. Free with a watermark (for testing), $9-29/month for unlimited HD
📄 2. Invoice Generators
Source: SimilarWeb, Octubre 2025
What it solves: Freelancers, consultants, and contractors need to send invoices, but:
- Word/Excel is unprofessional and slow
- Full accounting software (QuickBooks, Xero) is overkill and expensive ($30-50/month)
- They need something fast, beautiful, and ready to use now
How it works: User enters → Fills out fields (client, service, price) → Real-time preview → Downloads professional PDF or sends via automatic email. All in 2 minutes.
Real-life use cases:
- Freelance designer invoicing 5 clients/month
- Photographer sending an invoice after each session
- Tech consultant charging per project
- Construction contractor creating estimates + invoices
- VA sending recurring monthly invoices
Why they pay premium:
- Auto-email of invoices (they don't have to remember)
- Automatic recurring invoices (subscriptions)
- Multi-currency (they work with international clients)
- No watermark (more professional)
- History of all their saved invoices
The numbers:
- invoicefly.com → 167K visits/month
- skynova.com → 781K visits/month
- Session duration: 17 minutes (they are actually using it, not just browsing)
Keywords: "invoice generator", "freelancer invoice" (millions of searches)
The growth hack: Don't make a generic one. Create 10 specific versions by profession:
/invoice-template/freelancer→ Specific freelancer language/invoice-template/photographer→ With fields for sessions, editing, extras/invoice-template/graphic-designer→ With breakdown of concepts/revisions/invoice-template/contractor→ With estimates + materials + labor
Each page ranks for niche keywords with less competition than the generic term.
Stack: Next.js + jsPDF (generate PDFs) + Stripe (payments) + Supabase (save invoices) Time: 1 weekend Monetization: $9-15/month for premium features
📝 3. Resume Builders + AI
Source: SimilarWeb, Octubre 2025
What it solves: Everyone needs a resume (CV), but:
- Word templates are ugly and get messed up
- Canva requires design skills
- They don't know what to write or how to stand out
- ATS (Applicant Tracking Systems) reject 75% of resumes due to poor formatting
How it works: User chooses template → Fills out experience → AI suggests improvements ("Use action verbs," "Quantify results") → Real-time preview → Downloads PDF optimized for ATS. The resume passes automatic filters and reaches humans.
Real-life use cases:
- Recent graduate with no experience (AI fills gaps with skills/projects)
- Professional changing industries (AI adapts experience to the new field)
- Executive applying for C-level (AI emphasizes leadership/results)
- Nurse seeking a better hospital (specific healthcare format)
- Military transitioning to civilian life (translates military jargon to corporate language)
Why they pay:
- ATS check: Tells them if their resume will pass the automatic filter (this is gold)
- AI suggestions: They don't know what to write, AI does it for them
- Unlimited downloads: They will apply to 50+ jobs, they need to adjust the resume every time
- One-click job tailoring: Automatically adapts resume based on the job description
The numbers:
- "resume builder" → 673,000 searches/month
- "ai resume builder" → 90,500 searches/month (growing fast)
- enhancv.com → 10M users, 15M resumes created
The niche within the niche: There are a thousand resume builders, but you can target specific niches with low competition:
- Resume builder for nurses (480 searches, specific healthcare format)
- Resume builder for US government (6,600 searches, specific federal format)
- Resume builder for military (590 searches, translating military jargon)
Less competition = easier to rank = higher conversion because you speak their specific language.
Stack: Next.js + OpenAI API (AI suggestions) + React-PDF (templates) + Clerk (auth) Time: 3-4 days Monetization: $9-19/month for unlimited + AI + ATS checker
📈 Marketing Without Spending a Euro (How to Get Your First 1000 Users)
Building is easy. Getting found is the hard part.
Here is my marketing strategy for these micro-startups with a $0 budget:
SEO: The Free Traffic Machine
Month 1-2: Basic Content SEO
Create 10-15 specific pages per use case (as seen above). Each must have:
- Title with exact keyword: "Remove Background from Signature Online Free"
- H1 naturally repeating the keyword
- 300-500 words explaining the problem + solution
- Clear CTA to your tool
- Optimized images (ALT text with keywords)
Free tools:
- Google Search Console (tracks which keywords bring you traffic)
- Ubersuggest (5 free searches/day for keywords)
- AnswerThePublic (questions people are asking)
Quick SEO hack: Create a page "/vs/[competitor]" comparing yourself to every major competitor. Example: /vs/photoshop, /vs/canva. People constantly search "X vs Y".
Reddit: Your First Real Audience
Where to post depending on your SaaS:
- Background remover → r/ecommerce, r/smallbusiness, r/Entrepreneur, r/graphic_design
- Invoice generator → r/freelance, r/Entrepreneur, r/digitalnomad, r/smallbusiness
- Resume builder → r/resumes, r/jobs, r/careerguidance, r/GetEmployed
How to post without getting banned:
❌ NO: "Hey, I made this tool, try it [link]" ✅ YES: "I was sick of [problem], so I built [solution] this weekend. What do you think? [link + ask for real feedback]"
The key: Build in public, don't sell. 80% of your post should be the story/problem, 20% your solution.
Product Hunt: The Launch That Matters
Timing: Launch on a Tuesday or Wednesday (more traffic).
Preparation 1 week before:
- Teaser post on Twitter/X
- DM 20-30 makers asking for support on launch day
- Prepare 5-7 images/GIFs showing the product in action
On launch day:
- Upload at 00:01 PST (to be up all day)
- Reply to ALL comments in the first 60 minutes
- Post on Twitter every 2-3 hours with the link
Realistic goal: Top 5 of the day = 500-2000 visits + 50-200 signups.
Twitter/X: The Daily Growth Loop
"Build in Public" Strategy:
Post daily about your process (not about the finished product):
- Monday: "Starting to build [idea] today. Goal: launch in 7 days"
- Wednesday: Screenshot of the code/design + "Day 3, the main feature is working"
- Friday: "First 10 users. 3 have already paid. Here's what I learned: [thread]"
Engagement hack: Make threads with real data/numbers. Example: "I analyzed 50 resume builders. Only 3 actually use real AI. Here's what I discovered: [thread with screenshots + data]"
Threads with concrete numbers easily go viral.
My Challenge: I'm Going to Build One in Public
In the coming weeks, I will build one of these micro-startups and share:
- Real code (public GitHub)
- Daily metrics (traffic, conversion, revenue)
- Week-by-week marketing strategy
- Failures and what I learned
- If I achieve the first $100
Which one should I build? Reply to this email with the number:
- AI Background Remover - Fast to build, proven market
- Invoice Generator for Freelancers - A real problem I have myself
- AI Resume Builder - More complex but high potential
The one with the most votes wins. Your opinion counts.
