BeQuick, a software company run as a family business by two married couples for over 20 years, was sold to Banyan Software, whose policy is to "hold acquired companies forever." Neither hypergrowth nor a quick flip — M&A as "a form of retirement for a long-running business."

Josh Pigford, founder of the SaaS analytics tool Baremetrics, spent 6 months of due diligence and $20K in legal fees on his first acquisition talks — only for the buyer to disappear.

Jon Yongfook's image-generation API Bannerbear reached $10,455 MRR in January 2021 — after 7 failed products in a 12-startups-in-12-months challenge, Previewmojo plateauing at $400, and an API pivot that churned existing customers. He has published the numbers and tactics of every phase.

Pieter Levels's Avatar AI rode the early AI-avatar boom to roughly $150K in one week — the fastest money he had ever made.

Even Air HR, a Small HR Tool with $40K in Annual Revenue, Found a Buyer — the Market Where the "Smallest SaaS" Still Sells
Air HR, a small HR software business with $40K (about ¥6M) in annual revenue, was sold to payroll SaaS company KarbonPay. Even a SaaS at roughly ¥500,000 in monthly revenue can attract a strategic buyer — a case showing that the "too small to sell" line sits far lower than people imagine.
