I really don't intend this to sound condescending or arrogant in any way but a number the top 50 in Inc's 5000 are not businesses I would expect to be on the list. Yet, clearly they're doing something right. My question is, what are the key things they did right/different to achieve such growth?

Let's take a few specific companies as examples:

#11 - Small Business Owners of America provides short-term financing to businesses and offers services to startups, including incorporations, business plans, and pitch decks. SBOA has a 3-year growth rate of 12,060%

#13 - Suju Juice makes organic, cold-pressured, non-GMO juice beverages and has a 3-year growth rate of 10,511%

#21 - C&H Financial Services provides capital for small businesses, including loans, merchant cash advances, residual based lending, and e-commerce, mobile, and retail payment processing services. Its clients include nonprofits, municipalities, and restaurants. C&H has a 3-year growth rate of 8,053%

#22 - Paykings provides debit and credit card based payment processing services and has a 3-year growth rate of 7,905%

Again really don't mean to sound condescending but if you provided me nothing but the descriptions above, I would never guess these companies are in the Top 50 of Inc’s list. Clearly my knowledge is limited and I’m missing something here. Thoughts?
