How to Choose

For US-focused SaaS: Stripe (lowest fees, best API). For global SaaS with zero tax admin: Paddle or LemonSqueezy (they handle VAT/sales tax). For digital products: LemonSqueezy. The 2% fee difference between Stripe and Paddle is worth it if you value 5-10 hours/month saved on admin.

FAQs

Stripe or Paddle for micro-SaaS?

Stripe for lowest fees and maximum control (you handle taxes). Paddle for zero tax compliance (they are Merchant of Record, handling global VAT at 5%+50c per transaction).

What is a Merchant of Record?

A Merchant of Record (MoR) legally sells your product to customers, handling all tax collection, remittance, and compliance. Paddle, LemonSqueezy, and Polar are MoRs. Stripe is not.

Which processor has the lowest fees?

Stripe at 2.9%+30c. But you handle tax compliance yourself. MoR processors (Paddle, LemonSqueezy) charge 5%+50c but save 5-10 hours/month on global tax admin.

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.
