5 Dead Simple Business Ideas You Can Start With A FB Ad | ft. George Mack

George Mack is back for a more tactical episode—five business ideas he believes require no proprietary technology, no large team, and no significant capital to test. The filter is simple: can you validate the idea with one Facebook or Instagram ad before building anything? If yes, it belongs on the list.

The self-awareness test concept comes from Mack's observation that most people dramatically overestimate their own self-awareness while being surrounded by people who see them clearly. A paid assessment product—professionally delivered, uncomfortable but honest—could serve both individuals and companies who want to improve feedback cultures. The psychological insight is that people will pay for hard truths if the delivery mechanism feels authoritative rather than personal.

Iris Galerie is the real-world proof-of-concept for turning eyes into art: a company that photographs the human iris at extreme magnification, prints the result as large-format art, and sells it as a luxury home decor product. The photos are objectively beautiful and deeply personal. Mack's argument is that the underlying concept could be launched in any city with a macro lens, a Shopify store, and one targeted Facebook campaign.

Personal color analysis—the practice of determining which clothing colors flatter a person's skin tone, hair, and eyes—is having a cultural revival, driven partly by TikTok. Mack sees an obvious service business here: a consultant who charges $200-500 for a 90-minute in-person session, books through Instagram, and has zero overhead. The mold removal segment closes with a characteristically Mack observation: mold remediation is a high-margin, recession-proof business that is chronically fragmented and chronically under-marketed.
