At The Motley Fool, we've long advocated buying companies, not stocks. That means acting like a business owner and buying slices of companies you would want to own in their entirety. 

One of my favorite businesses is Trader Joe's. The combination of a quirky atmosphere, tremendous food, expanding stores, and high sales per square foot have me captivated. Every time I shop at one of its locations, I admire how it achieves so much (an estimated $1,750 in sales per square foot) in such a small space. 

Unfortunately Trader Joe's remains a private company, owned by the Albrecht family trust in Germany.

That sent me on a mission to find a company that could match Trader Joe's incredible operations that i could own, and I found it.
