How I Built a Tool for SaaS founders to Grow on Reddit Without Getting Banned — and Make $4K/Month

I wanted to get users for my SaaS on Reddit, but posting manually was a nightmare:

Posts got removed or accounts banned.

Subreddit rules were confusing and inconsistent.

AI-generated posts sounded robotic and often got flagged.

So I decided to build a tool https://www.leadlim.com to fix this. The goal: help SaaS founders grow on Reddit safely.

I built a system that:

Finds high-intent subreddits and analyzes their rules.

Generates AI-written posts that sound human and pass moderation.

Schedules posts at peak engagement times automatically.

It took a few months to tweak the AI and figure out the minimum viable features. But once it worked, I started using it for my own SaaS and then offered it to other founders.

The result?

Reddit growth became predictable and ban-safe.

I started making $4K/month from early users, mostly bootstrapped SaaS founders who needed a safe way to grow.

The lesson: solving a real pain (growing on Reddit safely) with a minimal, working tool can turn into revenue faster than you expect.

Curious: has anyone else built a tool to grow in risky communities like Reddit?
