Horizon3.ai joins the ranks of
Google, Nvidia, Adidas, Walmart, and more 

SAN FRANCISCO (March 24, 2026) — Horizon3.ai is proud to have been named to Fast Company’s prestigious list of the World’s Most Innovative Companies of 2026. This year’s list shines a spotlight on businesses that are shaping industry and culture through their innovations. Alongside the World’s 50 Most Innovative Companies, Fast Company recognizes 720 honorees across 59 sectors and regions.

“NodeZero® is the most experienced AI hacker in the world. It relentlessly seeks ways to compromise your network, break into your applications, steal your data, and lock you out of your systems using the same tactics the bad guys use,” said Snehal Antani, CEO and Co-founder of Horizon3.ai. “It’s no longer acceptable to wait for a breach to know your security worked. You need to proactively and continuously verify your secure posture.“

Horizon3.ai proved that organizations can safely execute real-world cyberattacks against their own production environments, something the industry long believed was too risky to do at scale. Traditional security models rely on identifying vulnerabilities or simulating threats, but they cannot determine what an attacker can actually exploit in a live environment. Through its NodeZero® Proactive Security Platform, Horizon3.ai enables continuous, real-world attack execution, removing that limitation and making it possible to measure risk based on what attackers can actually exploit.

As a result, Horizon3.ai shifts security from assuming defenses will work to proving they do. Security teams can observe how attack paths unfold across identity, cloud, endpoint, and infrastructure systems and validate whether controls detect or stop them. With continuous execution, validation, and retesting, Horizon3.ai enables an operational model where risk is measured through real outcomes and verified over time.

The World’s Most Innovative Companies is Fast Company’s hallmark franchise and one of its most anticipated editorial efforts of the year. To determine honorees, Fast Company’s editors and writers review companies driving progress around the world and across industries, evaluating thousands of submissions through a competitive application process. The result is a globe-spanning guide to innovation today, from early-stage startups to some of the most valuable companies in the world. 

“Our list of the Most Innovative Companies is about spotlighting organizations that don’t just adapt to change—they drive it,” said Brendan Vaughan, editor-in-chief of Fast Company. “The companies we honor this year are redefining what leadership looks like in 2026, pairing bold ideas with measurable impact and turning breakthrough innovation into real-world value. They are setting the pace for their industries and offering a blueprint for what sustained innovation can achieve.”

The full list of Fast Company’s Most Innovative Companies honorees can now be found at fastcompany.com. It will also be available on newsstands beginning March 31, 2026.

Fast Company will host the Most Innovative Companies Summit and Gala for honorees on May 19 in New York City. The summit features a day of inspiring content, followed by a creative black-tie gala including networking, a seated dinner, and an honoree presentation.
