The artificial intelligence sector in Montreal is characterized by a mix of established IT services firms and innovative software development companies. Companies like Logica, Alithya, and Equisoft provide IT and digital transformation services, while Lightspeed Commerce offers a cloud-based platform for retail operations. Hopper is a global travel platform, and Coveo specializes in AI-powered solutions for digital experiences. Mila is a research institute dedicated to deep learning. Most of these companies are mid-sized to large firms.
A notable pattern in this dataset is the strong presence of software development companies, often founded in the 2000s and 2010s, alongside older IT consulting firms. This suggests a mature technology ecosystem that has successfully integrated newer AI-focused ventures. All listed companies are headquartered in Montreal, indicating a localized hub for AI innovation.

Tamtam finds the decision-makers at every company on a list like this one, with verified emails, phone numbers and the buying signals that tell you when to reach out.
How this list is built
Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 12, 2026.
