Callum Mckeefery built Reviews.io from scratch with his wife—no funding, no equity dilution, and no fluff. In this episode, he shares how they scaled to $12M ARR, outpaced VC-backed competitors, and exited for $82M in an all-cash deal.

He breaks down the exact viral loop that created SEO-fueled growth, how they hit $240K revenue per employee, and why he chose not to give employees equity—but still made many millionaires. Callum also opens up about the emotional driver behind the exit: his son's rare genetic condition, and the cutting-edge research he's now funding.

Finally, Callum talks about his new SaaS startup, Partner.io, where he's rebuilding from zero with the same gritty playbook.
