QuSecure™, Inc., a leader in post-quantum cryptography (PQC) and cryptographic agility, today announced it has been ranked No. 526 on the 2026 Inc. 5000 list, the annual list of the fastest-growing private companies in America. The list is the most prestigious ranking of the nation’s most successful independent and entrepreneurial businesses, recognizing companies that have achieved remarkable growth while driving innovation, creating jobs, and shaping the future of the economy. Past honorees include companies such as Microsoft, Meta, and Oracle.
“Every company on the Inc. 5000 has a story of perseverance, smart decision making, and a refusal to sit still,” says Mike Hofman, editor-in-chief of Inc. “Their growth reflects more than strong financial performance – it reflects creativity, resilience, and the customer focus required to build companies that make a lasting impact. We congratulate all honorees on this significant achievement.”
This year’s Inc. 5000 recognizes a new class of companies redefining what growth looks like. The businesses included are expanding their impact, creating jobs and proving that entrepreneurial ambition continues to fuel the U.S. economy. Among the 5,000 companies on the list, the median three-year revenue growth rate was 130%, and those companies have collectively added more than 627,208 jobs to the U.S. economy over the past three years.
“It is rewarding to be recognized in such a high ranking on Inc.’s list of most successful private companies,” said Rebecca Krauthamer, QuSecure CEO and Co-Founder. “Fueled by the timelines for quantum-safe adoption shrinking to 2030, QuSecure anticipates even greater acceleration this year and next, as organizations hasten to address rapidly approaching compliance deadlines. Among our many growth markets are fed gov, banking, and telecom. 2026 is a very important year for QuSecure as the foundation for aggressive growth in the years to come.”
Companies on the 2026 Inc. 5000 list are ranked according to percentage revenue growth from 2022 to 2025. To qualify, companies must have been founded and generating revenue by March 31, 2022. They must be U.S.-based, privately held, for-profit, and independent – not subsidiaries or divisions of other companies – as of Dec. 31, 2025. (Since then, some on the list may have gone public or been acquired.) The minimum revenue required for 2022 is $100,000; the minimum for 2025 is $2 million. As always, Inc. reserves the right to decline applicants for subjective reasons.
