Hey there 👋 - Rahil here!

Happy Tuesday to the fellow AI builders

In today's edition, I wanted to share my ultimate tools stack required to build successful Micro SaaS

With so many tools out there, it’s easy to get caught in a spiral of endless comparisons and decision fatigue.

The truth?

Most successful founders don’t waste time reinventing the wheel. They rely on a proven stack of tools that cover everything from idea validation to scaling.

After testing over 50 tools last year, I’ve narrowed it down to the 15 essentials you need to dominate in 2025.

Real-World Insights: Lessons Learned from 50+ Tools

I wasted over $5,000 on unnecessary tools when I started building AI agents last year. If you're anything like me, you've probably spent countless hours comparing different tools, reading reviews, and second-guessing your tech stack decisions.

I made it my mission to test as many tools as possible. Here’s what I learned:

Tools like Fastwaitlist saved me weeks during pre-launch.

BorringStrategy offered marketing insights that doubled sign-ups.

I wasted weeks trying to build a custom changelog until Changelog simplified the process.

PRDGPT offered great product features ideas that our users loved.
