Founding and Growing ABC Supply

- Seeing an Industry Need:

“We felt like roofers weren’t being treated with respect. That was part of our goal: to build a company that would help the guy in the pickup truck…” – Diane Hendricks, as quoted by Simon Jack [12:16]
- 1982: During another recession, they risked everything as collateral for a $900,000 loan to buy three struggling supply businesses, founding ABC Supply.
“The bank explained to Ken [that entrepreneur] meant risk taker…and they didn’t do business with risk takers.” – Simon Jack [13:35]
- Rapid expansion: 3 locations and $4M sales to 25 locations and $82M in just two years.
“That is extraordinary growth from $4m to $82m in two years.” – Simon Jack [14:46]

- Financial Risks:
