In the three years since Bishop and Button purchased Verengo in a leveraged buyout (LBO), the company had gone through dramatic changes. Initially a residential windows and insulation firm, after the economic recession of 2008 the company switched gears and began offering solar installations to local residential customers. Aided by favorable regulatory changes and a consumer financing partnership, Verengo's solar business took off and became the company's primary focus. By the end of 2010, Verengo had grown to $27 million in revenue and was the largest solar integrator in Southern California. In December 2010, Verengo raised $9.7 million in growth equity funding and was considering its options for future growth. Eager to expand to markets outside of Southern California, Bishop and Button knew that they had to carefully assess the firm's many opportunities and tightly manage its growth.
