Inc. Magazine Reveals Annual List of America’s Fastest-Growing Private Companies—the Inc. 5000

For the seventh time, Curriculum Associates ranks among the Inc. 5000, with three-year revenue growth of 79.1 percent

North Billerica, MA, August 25, 2021

Inc. magazine revealed that Curriculum Associates is on its annual Inc. 5000 list, 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.

“We are honored to be recognized among the Inc. 5000 for the seventh consecutive year," said Rob Waldron, CEO of Curriculum Associates. "We have always believed that a long-term, mission-focused business model will drive the best results. As digital learning continues to be a priority for the upcoming school year, we look forward to continued growth and innovation in service of the more than 10 million students and educators we support.”

The companies on the 2021 Inc. 5000 have been not only very competitive with their markets, but also especially resilient and flexible through 2020's unprecedented challenges, which is proven by this year's list. Among the Inc. 5000, 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.

Complete results of the Inc. 5000, including company profiles and an interactive database that can be sorted by industry, region, and other criteria, can be found at The top 500 companies are featured in the September issue of Inc.

“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.”
