Halifax-based Site 20/20 has cracked Deloitte’s prestigious Technology Fast 50 list of Canada’s quickest-growing startups on the back of remarkable 2,392 percent revenue growth from 2019 to 2023.

Led by CEO Mitch Hollohan, Site 20/20’s flagship product is the Guardian SmartFlagger — a piece of equipment designed to replace the human “flaggers” who direct traffic at construction sites. It includes a portable stoplight and a barrier that can be lowered to block traffic flow.

Site 20/20’s inclusion in the Fast 50 marks the first time an Atlantic Canadian company has made the list since Introhive’s hat trick in 2019, 2020 and 2021. In sixth place, Site 20/20 has also posted the best-ever showing from an East Coast startup.

“This recognition underscores our dedication to creating safer job sites and more efficient management of resources,” said Hollohan in a statement. “We're honoured to be a part of this esteemed list and remain committed to setting new benchmarks in the industry.”

The Technology Fast 50 ranks companies based on their revenue growth over a four-year period. The participants are required to give Deloitte access to audited financial statements and must have already had revenue at the beginning of the four years.

Prior to Site 20/20, many of the East Coast companies to crack the Fast 50 have been from Newfoundland and Labrador.

The second year Introhive made the list, Mount Pearl, Newfoundland-based underwater robotics company Kraken also claimed the 36th position, while another Halifax company, Proposify, placed 45th. Earlier still, St. John’s-based cybersecurity software-maker Verafin made the list multiple times last decade, before it was sold to Nasdaq for US$2.75 billion.

This year, Mysa Smart Theromstats, likewise headquartered in St. John’s, also made Deloitte’s list of 15-fastest growing cleantech companies, building on its inclusion in the consultancy’s Companies to Watch list in 2021.

In addition to the Guardian, Site 20/20 also sells traffic cones capable of measuring the speed of passing cars in order to warn construction workers of fast-moving vehicles, as well as billing software for traffic control companies.

Hollohan founded the business in 2015 and launched the Guardian in 2017, under a revenue model whereby Site 20/20 leased the equipment to customers on an hourly basis. A single worker can control up to four of the machines using an iPad and video-monitoring software.
