Technology companies can grow at extraordinary speeds, but the artificial intelligence boom, cybersecurity demand, fintech innovation and business-software expansion have pushed some companies into an entirely different league.
The fastest-growing technology companies available to track in 2026 are not necessarily household names such as Apple, Microsoft, Google or Amazon. Many are younger companies building artificial intelligence platforms, cybersecurity tools, financial technology and specialized business software.
In the latest completed Deloitte Technology Fast 500 ranking available in 2026, the No. 1 company recorded an astonishing 29,738% revenue growth over three years.
This ranking looks at the top 10 companies in that dataset, from fintech company Parafin at No. 10 to AI-powered healthcare technology company Impiricus at No. 1.
How We Ranked the Fastest-Growing Tech Companies
For this TopMost10 ranking, we use the latest completed Deloitte Technology Fast 500 results available in 2026.
Deloitte’s Technology Fast 500 ranks rapidly growing technology, media, telecommunications, life sciences, fintech and energy-tech companies headquartered in North America.
Companies are ranked according to percentage fiscal-year revenue growth over a three-year period. The latest completed ranking measures revenue growth from 2021 through 2024.
This provides a much more consistent measurement than attempting to combine company valuations, stock-price increases, employee growth and revenue estimates.
Importantly, Deloitte’s 2026 winners are scheduled to be announced in November 2026. Therefore, this article uses the latest completed ranking available during 2026 rather than inventing a future result.
You can view the original ranking on the Deloitte Technology Fast 500 website.
10. Parafin — 9,594% Revenue Growth
Industry: Fintech
Headquarters: San Francisco, California
Three-Year Revenue Growth: 9,594%
Deloitte Rank: #10
Parafin takes the No. 10 position after recording an extraordinary 9,594% revenue increase over the measurement period.
The San Francisco fintech company builds financial infrastructure that enables online platforms and marketplaces to provide financial products to businesses.
Instead of requiring every digital platform to build lending and financial infrastructure internally, Parafin provides embedded financial technology that can be integrated into other platforms.
This business model reflects one of the most important developments in fintech: financial services increasingly operate inside software platforms that businesses already use.
Why Parafin Is Growing
- Growing demand for embedded finance
- Technology designed for digital platforms and marketplaces
- Expansion of financial services for small businesses
- Scalable fintech infrastructure

Deloitte Rank: #9
Gierd ranks ninth among the fastest-growing companies in Deloitte’s latest Technology Fast 500.
The company achieved 9,651% revenue growth during the three-year measurement period.
That means Gierd expanded its revenue by nearly 100 times relative to its starting point.
Companies at this stage of growth demonstrate how rapidly specialized software businesses can scale when they find a strong market and build technology that can serve customers without requiring physical expansion at the same rate.
Why Gierd Made the Top 10
- 9,651% three-year revenue growth
- Software-focused business model
- Rapid commercial expansion
- Strong position among emerging technology companies
8. Warmly — 10,460% Revenue Growth
Industry: Artificial Intelligence
Headquarters: Denver, Colorado

Deloitte Rank: #8
Warmly is the first company in our ranking to exceed 10,000% three-year revenue growth.
Deloitte classifies Warmly in the artificial-intelligence category and recorded revenue growth of 10,460%.
Warmly develops technology designed to help businesses identify and engage potential customers visiting their websites.
Its platform combines visitor identification, sales intelligence, automation and AI to help revenue teams discover potential buying opportunities.
The company’s growth reflects the wider boom in AI-powered sales and marketing technology.

Deloitte Rank: #7
Cyera ranks seventh after generating 11,823% three-year revenue growth.
The company operates in one of the hottest areas of enterprise technology: data security.
Organizations are storing increasingly large amounts of sensitive information across cloud platforms, software applications and AI systems. Understanding where that data exists and protecting it has therefore become an important cybersecurity challenge.
Cyera provides a data-security platform designed to help organizations discover, classify and protect sensitive information.
What Is Driving Cyera’s Growth?
- Increasing cybersecurity spending
- Rapid cloud adoption
- Enterprise concerns about sensitive data
- AI-related data-security requirements
- Growing regulatory pressure

6. JobTread Software — 11,944% Revenue Growth
Industry: Software & Services
Headquarters: Dallas, Texas
Three-Year Revenue Growth: 11,944%
Deloitte Rank: #6
JobTread Software takes sixth place with 11,944% revenue growth.
JobTread develops construction management software designed to help contractors manage projects, estimates, budgets, scheduling and customer relationships.
Construction has traditionally relied heavily on spreadsheets, paperwork and disconnected systems.
As contractors increasingly digitize their businesses, platforms that combine multiple project-management functions can benefit from strong demand.
Why JobTread Has Expanded Rapidly
- Digitization of the construction industry
- Cloud-based project management
- Integrated estimating and budgeting
- Software designed specifically for contractors

5. Farther — 11,968% Revenue Growth
Industry: Fintech
Headquarters: New York, New York
Three-Year Revenue Growth: 11,968%
Deloitte Rank: #5
Farther narrowly edges JobTread for fifth place with 11,968% three-year revenue growth.
The company combines financial advisors with technology to provide wealth-management services.
Financial technology has increasingly transformed the wealth-management industry as consumers and advisors expect better digital tools, easier portfolio access and more efficient financial infrastructure.
Farther’s position in the top five shows that fintech remains an important part of the high-growth technology landscape even as artificial intelligence attracts much of the industry’s attention.
Why Farther Is Growing
- Technology-enabled wealth management
- Growing demand for digital financial services
- Scalable advisor technology
- Expansion of the fintech industry
More information is available from Farther.
4. Red Rock Regeneration Inc. — 12,166% Revenue Growth
Industry: Life Sciences
Headquarters: Etobicoke, Ontario, Canada
Three-Year Revenue Growth: 12,166%
Deloitte Rank: #4
Red Rock Regeneration is the highest-ranked Canadian company in the top ten.
The Ontario-based company generated 12,166% three-year revenue growth, putting it fourth across the entire Deloitte Technology Fast 500.
Deloitte categorizes the company under life sciences, demonstrating that rapid technological growth is not limited to conventional software and artificial intelligence businesses.
Red Rock Regeneration also ranked first in Deloitte Canada’s Technology Fast 50, where Deloitte highlighted its exceptional three-year revenue expansion.
Why Red Rock Regeneration Stands Out
- 12,166% three-year revenue growth
- Highest-ranked Canadian company in the Fast 500 top ten
- Life-sciences technology exposure
- Rapid commercialization
3. Horizon3.ai — 19,939% Revenue Growth
Industry: Software & Services / Cybersecurity
Headquarters: San Francisco, California
Three-Year Revenue Growth: 19,939%
Deloitte Rank: #3
Horizon3.ai moves the ranking into another level of growth.
The cybersecurity company recorded an astonishing 19,939% revenue increase over three years.
Horizon3.ai develops the NodeZero autonomous penetration-testing platform.
Penetration testing attempts to identify security weaknesses by testing systems from an attacker’s perspective.
Traditionally, penetration testing can require significant manual work. Horizon3.ai uses automation to help organizations continuously identify exploitable weaknesses in their systems.
The company said its growth has been driven by enterprise adoption of its autonomous security technology.
Why Horizon3.ai Is Growing So Quickly
- Increasing cybersecurity threats
- AI-powered security automation
- Demand for continuous security testing

Deloitte Rank: #2
Lpt Aperture Holdings came extremely close to taking the No. 1 position.
Deloitte recorded 29,462% revenue growth for the company during the three-year measurement period.
That is more than double the growth rate of the fourth-ranked company and only slightly behind Impiricus.
Its performance illustrates just how extreme the growth rates can become among relatively young technology businesses starting from smaller revenue bases.
Why Its Growth Is Remarkable
- 29,462% three-year revenue growth
- Second-highest growth rate in the entire Fast 500
- Software and services business model

What Does 29,738% Revenue Growth Actually Mean?
A growth rate of 29,738% does not mean Impiricus grew by 29,738% every year.
It represents the percentage increase in revenue across Deloitte’s three-year measurement period.
These enormous percentages are also easier for relatively young companies to achieve because they may begin the measurement period with a comparatively small revenue base.
A mature company generating hundreds of billions of dollars in annual revenue would find it virtually impossible to produce the same percentage increase.
Artificial Intelligence Is Creating New Growth Leaders
AI is one of the clearest themes in the ranking.
Impiricus and Warmly are explicitly categorized by Deloitte as artificial-intelligence companies, while AI and automation are also becoming increasingly important across cybersecurity, fintech and enterprise software.
The growth demonstrates how businesses are moving from experimenting with artificial intelligence to paying for AI-powered products that solve specific commercial problems.
Cybersecurity Is Another Major Growth Market
Cyera and Horizon3.ai demonstrate the strength of cybersecurity technology.
Companies are storing more data in cloud platforms, employees are accessing corporate systems from more locations, and artificial intelligence is creating additional security challenges.
Businesses therefore need tools capable of identifying vulnerabilities, protecting sensitive information and continuously monitoring their technology environments.
Why Apple, Microsoft and NVIDIA Aren’t on This List
Some readers may expect to see giants such as Apple, Microsoft, NVIDIA, Amazon or Google.
They are absent because this ranking measures percentage revenue growth, not total revenue, market capitalization or brand value.
Large technology corporations may add tens of billions of dollars in revenue while still producing a much smaller percentage growth rate than a younger company starting from a smaller base.
That is why a fastest-growing-company ranking looks very different from a ranking of the world’s biggest companies.

Final Thoughts
The fastest-growing technology companies available to track in 2026 show that some of the most explosive business growth is occurring far beyond the familiar names dominating the stock market.
Impiricus leads the latest completed Deloitte Technology Fast 500 with 29,738% three-year revenue growth, narrowly ahead of Lpt Aperture Holdings at 29,462%.
Horizon3.ai follows with 19,939%, while Red Rock Regeneration, Farther, JobTread Software and Cyera all achieved growth above 11,000%.
The broader pattern is particularly interesting. Artificial intelligence, cybersecurity, fintech and specialized enterprise software are producing some of the fastest-scaling companies in the technology economy.
As the AI boom continues and businesses spend more on automation, cybersecurity and digital infrastructure, the next generation of technology leaders may emerge from companies that many consumers have barely heard of today.
We will update this ranking when Deloitte publishes the 2026 Technology Fast 500 results.
