Ghost Cofounder vs Polsia: The Honest Comparison

Polsia launched on Product Hunt recently and got a lot of attention. They're calling themselves an "AI cofounder" too. So let's compare honestly, because founders deserve to know what they're actually signing up for.

The revenue share problem

Polsia charges $99/month. That sounds reasonable. But buried in their pricing is a 20% revenue share on anything the AI helps generate.

Let's say your AI cofounder helps you close $5,000 in new business this month. You pay $99 plus $1,000 to Polsia. Next month it helps you land a $20K client. That's another $4,000.

There's no cap. There's no ceiling. As your business grows, Polsia's cut grows with it.

Ghost Cofounder charges a flat rate. We never take a percentage of your revenue. Not 20%. Not 1%. Zero. Your wins are your wins.

What they actually do

Polsia:
- 1 task per night
- 5 on-demand credits per month
- AI generates the plan, you execute it

At 5 credits a month, that's roughly one useful output every 6 days. For $99 plus a piece of your revenue.

Ghost Cofounder:
- Starter: 30 tasks per month (every day, multiple types)
- Growth: unlimited tasks, priority execution every 2 hours
- Every task is a complete deliverable — competitor brief, content draft, SEO audit, outreach copy

The difference: we execute. Not plan. Execute.

"AI cofounder" — but who does the work?

This is the core question. An AI cofounder should take work off your plate, not add items to your to-do list.

Polsia gives you insights and recommendations. You still have to open the laptop and do the thing.

Ghost Cofounder runs competitor analysis, identifies your gaps, drafts the content, and delivers it to your inbox. You wake up to finished work, not a suggested agenda.

Quality of execution

This is harder to compare because it's subjective. But the Product Hunt comments on Polsia's launch tell a story:

• "The outputs feel a bit generic"
• "Interesting but I'd need to heavily edit everything"
• "More like a starting point than finished work"

We're not perfect either. Every AI output needs a human eye before it goes live. But we use Claude (Anthropic's frontier model) for content work and genuinely tune the prompts to each company's voice and context. If you see "generic" in your outputs, tell us. We fix it.

Who should use Polsia?

Honestly? If you want a structured AI advisor who gives you a daily to-do list and you're comfortable executing it yourself, Polsia might work for you. It's a clean product with a clear interface.

But if you're a solo founder who's already doing everything and needs actual work done — not more work assigned — Ghost Cofounder is built for you.

The real question

Do you want an AI that tells you what to do, or an AI that does it?

That's the choice.
