Digital security management startup ZeroTek is one of three Ottawa-based ventures to secure a spot on a prestigious list of up-and-coming Canadian companies.
The firm posted two-year revenue growth of 355 per cent, good for 13th place on Deloitte’s 2025 ranking of tech companies to watch released Thursday.
Launched in 2020, ZeroTek specializes in software that helps managed service providers protect their customers’ digital identities. The technology allows MSPs to administer multiple clients’ Okta accounts – software from California-based Okta that lets users access a range of software applications with a single, digitally secure sign-in method such as a code sent to their cellphones – in a single platform.
ZeroTek’s products are now used by hundreds of customers, mainly in the United States.
“When we looked at the landscape, we saw that MSPs needed more than what traditional identity platforms could offer,” Neil Arsenault, ZeroTek’s chief executive and chief technology officer, explained in an email to OBJ on Thursday.
“Most solutions were built for single enterprises, not for providers managing dozens to hundreds of clients. This gap became our opportunity to create real value – to empower MSPs to deliver scalable, affordable, enterprise-grade identity security to the SMBs that depend on them.”
The 15 firms on Deloitte’s companies-to-watch list must have been incorporated for at least three years and needed to prove minimum revenues of $50,000 in 2022 and $2.5 million in 2024.
Two other Ottawa companies also made this year’s list. FundMore.ai, a fintech startup that uses artificial intelligence to streamline the mortgage approval process, came in at No. 6 with two-year revenue growth of 708 per cent, while H2 Analytics, which makes training software for defence forces, law enforcement agencies and other customers, finished in 12th spot with two-year growth of 358 per cent.
Meanwhile, another Ottawa company that’s no stranger to such rankings made Deloitte’s list of the 50 fastest-growing tech firms in Canada.
TryCycle Data Systems, which specializes in apps that provide clinical and peer-to-peer mental health support to Indigenous groups, military veterans and other users, came in at No. 21 with three-year revenue growth of 1,508 per cent.
It’s the latest accolade for the fast-rising firm, which took second spot in OBJ’s 2025 list of Ottawa’s fastest-growing companies after finishing third the previous year.
TryCycle was the only local company to crack this year’s Deloitte Technology Fast 50 ranking. Qualifying companies must have been in business for at least four years, have a minimum revenue of $50,000 in 2021 and $5 million in 2024, be headquartered in Canada, own proprietary technology, and invest a minimum of five per cent of gross revenues in R&D activities that are conducted in Canada.
Deloitte also published a list of the country’s fastest-growing enterprise-level companies. Health-tech firm Fullscript was the lone Ottawa company to make the cut this year, generating three-year revenue growth of 246 per cent to place 14th out of 17 entries.
