Company ranked as the ninth fastest-growing engineering firm in the U.S.

Castillo Engineering’s Inc. 5000 recognition places the company in the top 0.07 percent of all private companies in the U.S. in terms of multi-year growth.

Maitland, FL, August 17, 2022 Castillo Engineering, a leading national design and engineering firm that delivers expertise in full service solar and energy storage design, engineering, and consulting services, announced that they have been named to Inc. 5000’s esteemed list of fastest-growing companies in America for the second consecutive year. The Inc. 5000 recognition puts Castillo Engineering in the top 0.07 percent of all privately-owned companies in America in terms of multi-year growth. Castillo Engineering was also ranked by Inc. as the ninth fastest-growing engineering firm in the United States due to its extraordinary year-over-year revenue growth of 595 percent.

“We are honored to have made the Inc. 5000 list for the second year in a row,” said Christopher Castillo, CEO of Castillo Engineering. “Our immense growth would not be possible without our talented, passionate, and process-driven team, as well as our repeat customers, who continue to have strong confidence in our design and engineering expertise.”

The Inc. 5000 list of the fastest-growing, privately held companies in the United States was first introduced by Inc. in 1982. Since then, the Inc. 5000 list has become a hallmark of entrepreneurial success in the country. Companies on the 2022 Inc. 5000 have been ranked according to percentage revenue growth from 2018 to 2021. Notable companies that were previously named to the Inc. 5000 list include Microsoft, Oracle, Intuit, Zappos, Under Armour, Pandora, and Patagonia.

“The accomplishment of building one of the fastest-growing companies in the U.S., in light of recent economic roadblocks, cannot be overstated,” says Scott Omelianuk, Editor-in-Chief of Inc. “Inc. is thrilled to honor the companies that have established themselves through innovation, hard work, and rising to the challenges of today.”

A conference and gala will be held for the Inc. 5000 list honorees in Phoenix, Arizona, from October 19th through the 21st.
