Start a Micro-SaaS with $0

You can build a profitable micro-SaaS without spending a single dollar upfront. The tools are free. The hosting is free. The payments are free to set up. The only investment is your time — 5 hours per week. Here's the complete $0 stack and how to use it.

What You Can Afford

✓ A landing page on Vercel free tier (100GB bandwidth)
✓ Frontend built with Cursor or Bolt.new free tier
✓ AI features via OpenAI/Anthropic free credits or open-source models
✓ Email via Resend free tier (3,000 emails/month)
✓ Payments via Stripe (no monthly fee, 2.9% + 30¢ per transaction)
✓ Domain via free subdomain (.vercel.app) — upgrade later

What You Cannot (Yet)

✗ Custom domain (costs $12/year — upgrade after first paying customer)
✗ Premium AI API calls at scale (budget $20/month once you have 5+ customers)
✗ Paid advertising (rely on organic: Reddit, SEO, communities)
✗ Paid tools like Notion, Figma (use free alternatives)

FAQ

Can I really start a micro-SaaS with literally $0?

Yes. Vercel, Supabase, Resend, PostHog, and GitHub all have generous free tiers. Stripe charges per transaction, not a monthly fee. The only 'cost' is your time. Many successful micro-SaaS founders started with nothing but a free weekend.

What's the catch with free tiers?

Free tiers have limits: Vercel caps at 100GB bandwidth, Supabase at 500MB database, Resend at 3,000 emails/month. These limits are generous enough to support your first 50-100 customers. You won't hit them until you're generating meaningful revenue.

When should I start paying for tools?

After your first 5 paying customers. At that point, $100-150/month in tool costs is easily covered by $145-$485 MRR. Don't optimize for cost before you have revenue — optimize for speed.

Calculate Your Freedom Number

What Invisible Exit Is

Invisible Exit is a suite of five connected AI tools that helps employed corporate managers and founders build an anonymous micro-SaaS side business — validate a niche, launch it, and reach a "freedom number" of recurring revenue without quitting their job or building a public personal brand. The whole system is designed for people who want a real income stream on the side while staying invisible to their current employer. Plans start at $0.97/month.

The Five Tools

Freedom Number Dashboard

Calculates the monthly side income that would cover your living expenses, so you know the exact target that makes leaving your job optional rather than desperate.

Idea Validation

A library of 500+ micro-SaaS ideas scored by industry fit, time investment, and revenue potential, plus AI-powered validation of your own idea in about 48 hours — so you build something people will pay for.

Compliance & Anonymity

Entity-separation and digital-invisibility guides plus a compliance audit against the clauses that trip up employed founders — non-compete, IP-assignment, and moonlighting terms — so you keep devices, accounts, and domains cleanly separate from your employer.

Launch Automation

Go-live tooling built for a five-hour weekend: Stripe integration, landing-page generation, and a launch-sequence builder that take you from idea to a live paid product.

Faceless Audience Builder

YouTube scripts, Reddit playbooks, and SEO content templates that build demand without ever showing your face or attaching your real name.

What Invisible Exit Is Not

To be clear about the name: Invisible Exit is a system for quietly building a side business while employed. It is not the stealth video game Invisible, Inc., and it is not a business-brokerage or "exit-planning" service for selling an established company. The "exit" here is your personal path out of a 9-to-5, built invisibly.

Frequently Asked Questions

What is Invisible Exit?

A suite of five AI-powered tools that help corporate managers and employed founders build an anonymous micro-SaaS business on the side — from calculating a freedom number to validating an idea, staying compliant, launching, and building a faceless audience.

Can I build a side business while employed without my employer finding out?

Yes. Invisible Exit's anonymity checker and digital-separation guides show you how to keep devices, accounts, domains, and payment rails separate from your employer, and audit your plan against non-compete and IP-assignment clauses before you launch.

What is a freedom number and how do I calculate it?

Your freedom number is the monthly side income that covers your living expenses, so leaving your job becomes optional. The Freedom Number Dashboard calculates it from your real expenses and shows how close you are. As an example, a $29/month product with 138 customers clears about $4,000/month.

How much does Invisible Exit cost?

Invisible Exit starts at $0.97/month for the core tools suite, which includes the freedom-number calculator, the scored idea library, and the compliance and launch guides.

Do I need a personal brand to build a side business?

No. Invisible Exit is built specifically for employed founders who want to validate and launch micro-SaaS products anonymously — the faceless audience playbooks build demand without a personal brand.
