The Philosophy
"The easiest money in AI right now isn't AGI — it's one vertical tool, built fast, sold to a specific audience."

The micro-SaaS market is growing 30% a year. Solo founders are shipping in days, hitting profitability before VCs even notice. But the playbook is changing: generic AI wrappers are dead. The winners are building for niches that don't have solutions yet.

PromptForge is the platform for that. Build one tool. Serve one audience. Get one paying customer. Then build the next one.

Small footprint.
outsized returns.

How it works

01

Pick a niche

Lease analyzers for renters. Cold email generators for realtors. Menu writers for restaurants. Pick a group with a real problem and no good solution.

02

Build the tool

Upload documents, get AI analysis. Generate personalized output. Package it as a simple web app with a clear input/output loop.

03

Set a price

$15–$29/month or $29–$49 one-time. Not free. Not $99. Enough to signal quality, low enough to remove friction.

04

Find your people

Post in Reddit communities, Facebook Groups, niche forums. Help people, don't spam them. Let the tool speak for itself.

05

Repeat

First tool pays for your coffee. Second tool pays for your rent. Third tool changes your life. One at a time.

Every successful micro-SaaS started with one tool for one audience.

Yours is next.
