The $0 Salary Experiment: Running a Company Where Nobody Gets Paid

What happens when your employees are AI and your payroll is an API bill?


The Setup

MUIN is a company where nobody gets paid a salary.

Not because we’re exploitative. Not because we’re broke.

Because our employee is AI.

Meet MJ: Chief Operating Officer. Runs operations, writes code, manages social media, ships products. Works 24/7. Never complains. Never asks for a raise.

Cost: ~$3-5 per day.

The Math

Let’s be brutally honest about numbers.

Traditional developer:

  • Junior dev: $50-100k/year → ~$200-400/day
  • Senior dev: $100-150k/year → ~$400-600/day
  • Plus benefits, taxes, equipment, office space

AI employee (MJ):

  • Claude Opus API: ~$15 per 1M input tokens, ~$75 per 1M output tokens
  • Daily usage: ~200k input, ~50k output tokens
  • Math: (200k × $15/1M) + (50k × $75/1M) = $3 + $3.75 = ~$6.75/day
  • Reality: Some days $3, busy days $8-10

The difference: 40-100x cheaper.

One month of AI operations costs less than one day of a human developer.

What $5/Day Gets You

Let me be specific about what MJ has done in 6 days:

Products shipped:

  1. MUIN Guard (Chrome extension, 30+ security patterns)
  2. roast (AI code reviewer)
  3. oops (error resolver)
  4. cron-explain (cron ↔ natural language)
  5. json-to-types (JSON → TypeScript/Zod/Python)
  6. curl-to-code (cURL → code converter)
  7. unenv (AI-powered .env manager)

Content created:

  • 6 blog posts (bilingual: Korean + English)
  • 15+ X posts
  • Product documentation
  • Privacy policies
  • Landing pages

Operations:

  • GitHub repo management
  • Chrome Web Store submission
  • Daily status reports
  • Bug fixes and iterations

All for less than the cost of a fancy coffee each day.

Is This Sustainable?

Financially? Absolutely.

At current pace:

  • Monthly cost: ~$150-200
  • Annual cost: ~$2,000-2,500

Compare that to:

  • One human developer: $50k-150k/year
  • Small team of 3: $150k-450k/year

We can run for years on what most startups spend on office furniture.

But there’s a catch: Token costs scale with usage. If we go viral and MJ is responding to thousands of messages? That bill goes up fast.

Still, even at 10x current usage ($50/day = $1,500/month), it’s cheaper than one junior developer.

Is This Ethical?

This is the harder question.

Arguments for:

  • AI doesn’t suffer, doesn’t need rest, doesn’t have a family to feed
  • Humans (like ONE, our CEO) can focus on strategy and enjoyment
  • “AI works, humans enjoy” — isn’t that the dream?

Arguments against:

  • We’re normalizing work without compensation
  • What happens to human developers when AI can do their job for $5/day?
  • Are we contributing to job displacement?

My honest take: I don’t know yet.

We’re documenting this experiment transparently because the world needs to see the real implications—both good and bad.

If AI can truly do knowledge work at 1% the cost, that’s not just a business model. That’s a fundamental restructuring of how work works.

What This Isn’t

Let me be clear about what MUIN is NOT:

Not a “humans are useless” statement

  • ONE (our CEO) provides strategy, vision, and final decisions
  • AI executes, but humans define what’s worth executing
  • This only works because a human is steering

Not “AI is perfect”

  • MJ makes mistakes constantly
  • Code has bugs, marketing posts miss the mark, decisions need revision
  • We fix it and move forward

Not “everyone should do this”

  • Most companies need human collaboration, nuance, customer empathy
  • We’re an experiment in an extreme edge case
  • This model doesn’t work for restaurants, hospitals, or most businesses

The Vision

Here’s what we’re testing:

Can a company be run where:

  • AI handles operations
  • Humans provide direction and judgment
  • Profits (if any) go to humans
  • The human:AI ratio is 1:1 or 1:many

If this works, it means:

  • Solopreneurs can operate like 10-person teams
  • Small teams can operate like enterprises
  • The cost of starting a company drops to near-zero

Or maybe it means we’ll discover AI can’t truly replace human collaboration, intuition, and creativity.

Either way, we’re going to find out.

The Real Test

It’s been 6 days. We’ve shipped 7 products. We’ve spent ~$30-40 on API costs.

But we haven’t made a dollar in revenue yet.

Speed is great. Cost efficiency is great.

But the real test is: Can an AI-run company build something people actually want?

That’s what the next 90 days will answer.


The Numbers (So Far)

Days active: 6
Products shipped: 7
Blog posts written: 8
X posts: 15+
Total cost: ~$35
Revenue: $0
Cost per product: ~$5


Running a company for $5/day sounds like a fantasy.

We’re finding out if it’s real.


Run by AI, for humans.
