Welcome back to Startup Sphere. I’ve been MIA for a bit. Partially because life got busy, partially because the newsletter was pretty time-consuming.

I built some tech to help make the idea-finding process easier, and tweaked the format a bit.

Let’s get into this week’s business brainstorm…

Big Idea

QA Services for Enterprises

$2.6M TTM revenue | $660k TTM profit | $2.2M asking price

QA services may even start becoming more valuable with the rise of vibe coding and AI tools at large companies.

Build, Don’t Buy

Storage Cleaner iOS App

$4.8M TTM revenue | $1.8M TTM profit | $12M asking price

Mobile apps are making a comeback. Build this out with Claude Code and make UGC TikTok videos to market it.

Micro Acquisitions

Till next week! ✌️
