Ten of the fastest-growing technology companies in North America are from Austin.

Built In has compiled the fastest-growing Austin companies based on Deloitte’s annual Technology Fast 500 report, which ranks companies based on their revenue growth over the past three years. The 2021 edition of the report was released Wednesday. 

Austin’s showing on the list improved over last year, when eight ATX companies made the cut. The list spans a wide variety of industries, including logistics, fintech, media, biotech and more.

Blue Prism continues to grow, although its pace has slowed slightly as the company dropped from #127 to #269 on this year’s Fast 500 list. Through its robotic process automation, Blue Prism creates a “digital workforce” that automates administrative processes, creating efficiency and freeing up human employees to take on other projects. The company has more than 2,000 customers in 170 countries and 70 industry verticals. In January 2019, the company raised $130 million by issuing new stock.


Rank #172, 773% Growth

AlertMedia’s software allows organizations to send mass notifications to employees during critical events like severe weather, terror attacks or other disruptions. The company, which has doubled its revenue every year since it was founded, has added nearly 1,000 new customers in the past year, boosting its client list to nearly 3,000 organizations. The company raised $15 million in April 2020, boosting its total fundraising to $57 million, according to Crunchbase. The company plans to open a new office on the top two floors of the 15-story RiverSouth building in the spring of 2022.

OJO Labs continues to be a hot startup, maintaining its #29 rank since last year’s Fast 500 list. The company offers an end-to-end platform for buying and selling homes powered by an AI assistant that helps buyers and sellers navigate the process. In June, the company announced it raised a $62.5 million Series D round, bringing the company’s total fundraising to $133.5 million. Part of the funds were used to acquire real estate website Movoto.


Rank #26, 8,288% Growth 

By streamlining scientific processes and data management, L7 Informatics’ automation technology is designed to help life science and healthcare enterprises simplify processes and automate workflows to facilitate breakthrough efficiencies, reduced costs and more. The company last raised a $13 million Series B in March 2021, bringing its total funding to more than $24 million, according to Crunchbase. 


Rank #4, 32,670% Growth

The fourth-fastest-growing technology company in North America is Austin’s very own Shipwell, which has seen staggering revenue growth in recent years. The startup uses artificial intelligence and cloud computing to help businesses automate and optimize their supply chain. The company last raised a $35 million Series B round in October 2019, bringing its total funding to $47 million.
