ARLINGTON, VA, August 17, 2021.– Quantitative Scientific Solutions revealed today that for the 2nd consecutive year it has been named to the annual Inc. 5000 list, appearing at No. 1636 on the most prestigious ranking of the nation’s fastest-growing private companies. The list represents a unique look at the most successful companies within the American economy’s most dynamic segment—its independent small businesses. Intuit, Zappos, Under Armour, Microsoft, Patagonia, and many other well-known names gained their first national exposure as honorees on the Inc. 5000.

“To be recognized by the Inc. 5000 in the current climate is a true testament to the incredible team of diverse and talented people that we have here,” said Dr. Thomas Armel, QS-2 Founding Partner and President. “QS-2 has grown into a leading science and technology consulting firm because of our team. Their dedication and talent are what makes QS-2 and our clients so successful, and we look forward to continuing to build upon that success.”

This year’s Inc. 5000 nomination comes after QS-2 recognized a 3-year growth of over 311%, and despite the challenges that 2021 has presented is already on pace to build upon this exceptional growth as the company continues to diversify and expand its clients and services.

Not only have the companies on the 2021 Inc. 5000 been very competitive within their markets, but this year’s list also proved especially resilient and flexible given 2020’s unprecedented challenges. Among the 5,000, the average median three-year growth rate soared to 543 percent, and median revenue reached $11.1 million. Together, those companies added more than 610,000 jobs over the past three years.

“The 2021 Inc. 5000 list feels like one of the most important rosters of companies ever compiled,” says Scott Omelianuk, editor-in-chief of Inc. “Building one of the fastest-growing companies in America in any year is a remarkable achievement. Building one in the crisis we’ve lived through is just plain amazing. This kind of accomplishment comes with hard work, smart pivots, great leadership, and the help of a whole lot of people.”
