Radius: From $708 in Year-One Revenue to a 6x-Revenue Exit 13 Years Later — an Insurance CRM Sold With No Broker, in a Two-Front Negotiation

Klipy: COVID Debt, Six Wasted Years — How a 3-Person AI CRM Reached 5-Figure MRR and 4,000 Companies
Jung Hong Kim, who had sold two machine-vision companies, lost his third to COVID and was left in debt.

Jenni AI: From $2K MRR to $6M ARR on 12,000 TikToks a Month — Examining the “Creator Factory” Marketing
AI writing-assistant Jenni AI went from a stalled $2K MRR to $6M ARR and 3 million users by systematically mass-producing short-form videos on TikTok/Reels. At its peak, 200+ creators were posting 12,000 videos a month — a textbook case of modern "industrialized virality."

Diego Roshardt built an MVP in two weeks and started charging from day one. About a year after launch, he passed $10,000 MRR.
