While the world was debating whether the AI market would crash or accelerate even further, a previously unknown company called Impiricus grew its revenue from fifty thousand dollars to almost fifteen million in just three years. The growth rate reached 29,738 percent. This is not a typo. The company secured first place in the latest Deloitte Technology Fast 500 ranking, which highlights the fastest growing tech companies in North America.

Impiricus focuses on a simple yet transformative idea: it uses AI to connect physicians with pharmaceutical companies without violating ethical standards or legal regulations. Patients receive access to new medications more quickly, physicians gain timely information, and pharmaceutical companies reach the practitioners who truly need the data. In second place, with a similarly extreme growth rate of 29,462 percent, is the opaque Lpt Aperture Holdings from Florida. Little is publicly known about it except that it develops software that dramatically boosts business performance.

Third place went to Horizon3.ai from San Francisco, a company that enables machines to detect vulnerabilities in corporate security systems and fix them autonomously. With a growth rate of 19,939 percent, its technology functions as a life-saving tool in an environment where approximately 2,200 companies are hacked every day.

New Leaders, Old Rules

Only one company in the top ten is not American: Red Rock Regeneration from Canada, which focuses on regenerative medicine and reported 12,166 percent growth. The rest of the top tier is dominated by New York, San Francisco, Dallas, Denver, and even Idaho, represented by Gierd with 9,651 percent growth. The Bay Area continues to hold 17 percent of all winners, but for the first time in many years Canada surpassed every other region with 23 percent of the entire list. Florida, which once ranked among the top three regions, dropped out of the top ten entirely.

Artificial intelligence is the dominant theme of the year. While AI held a modest position in last year’s statistics, it has now risen to fourth place among all sectors and delivered the strongest average growth rate at 407 percent. Fintech and life sciences switched positions: fintech slowed slightly, although Farther from New York still posted 11,968 percent, while biotech surged ahead.

And Where Are the Giants?

They are almost entirely absent. Seventy percent of the companies in the ranking are privately held, and many do not disclose their exact revenue figures. These are not the likes of OpenAI or Nvidia. Instead, they are firms building the tools that support other tools. Cyera secures data with a growth rate of 11,823 percent, Warmly uses AI to optimize lead generation with 10,460 percent, and Parafin offers one click small business lending with 9,594 percent.
