The Vandersloot Family – $3.4B
Frank Vandersloot’s brother-in-law actually founded Oil of Melaleuca, which sold tea tree oil. At the time, it didn’t have enough space on the market to be successful. In addition, the company ran into some issues with the FDA due to accusations of inflating medical stats to make their product more saleable. Frank ended up dissolving the company, later referring to it as “a mess” in interviews. Melaleuca was later rebooted by Frank himself, and now sells nutritional supplements, cleaning supplies and homecare products.

The Kibar Family – $2.8B
Osman Kibar founded the biotech firm Samumed (he also serves as the CEO), which is largely focused on anti-aging meds. Because of the success of the firm, its value is now placed at $12.4 billion. Kibar also founded two more companies, though he didn’t have a management position in the companies. The drug giant Pfizer originally owned Samumed, but after a falling-out, Samumed is now independent.
