Montreal is one of the easiest places in North America to find a software team. Montréal International counts more than 180,000 tech workers in Greater Montréal and more than 100,000 profiles with software development skills (source). The harder part is choosing: the city has AI research spinoffs, mobile studios, Microsoft and data specialists, and full product development firms, and they all describe themselves as custom software builders.
This guide compares eight custom software development companies in Montreal, each headquartered in the city, using facts you can check on each firm's website and Clutch profile. Every claim links to its source. For the national picture, see our list of custom software development companies in Canada, and for the global market see the top custom software development companies in 2026.
How to choose a custom software company in Montreal
Most Montreal shortlists come down to a few practical questions:
- What you are building. A connected device app, a data platform, an internal management tool, and a SaaS product need different strengths. Ask for case studies that match your type of software.
- French and English. Quebec organizations often need interfaces, documentation, and meetings in French. Ask who on the delivery team works in French, and put French deliverables in the statement of work if you need them.
- Who writes the code. Several Montreal firms stress that all work stays in house and local. If that matters to you, confirm it in the contract.
- Security evidence. SOC 2 and ISO 27001 matter if your customers or auditors will review the vendor. Ask for the current report or certificate, not a logo.
- Project size. Clutch minimum project sizes for the firms below range widely. A firm that prefers large programs may not be the best partner for a focused first release, and the reverse is also true.

The companies
1. Webisoft
Webisoft is a Montreal based software development firm founded in 2016, with a second office in Miami (source). It builds enterprise software, custom products, SaaS platforms, and AI systems with senior North American engineers, and works in English and French (source). Webisoft holds an AICPA SOC 2 Type II attestation, is HIPAA compliant, and is both an AWS Partner and an Odoo Partner (source). Its Clutch profile shows a 4.9 rating across 23 reviews, with custom software development as its largest service line (source). Our product development teams take a project from discovery to launch and then keep integrating it with the ERP, CRM, and identity systems around it. Webisoft is smaller than the largest Montreal teams, so it is not the right choice for a program that needs hundreds of people at once. It tends to fit Montreal and North American organizations that want one senior, bilingual team to own a custom build end to end, with security compliance already in place for procurement.
2. Beslogic
Beslogic lists Montreal as its headquarters on Clutch, with a founding year of 2008 and 50 to 249 employees (source). Its site describes it as a Montreal and Paris based company and groups its expertise into artificial intelligence, software development, and data and digital strategy (source). Beslogic also sells ARI, an on premises AI tool for secure document search across public and private file sources (source). On Clutch, custom software development and AI development are its two largest service lines, followed by IT staff augmentation, and the profile lists a minimum project size of $10,000+ and an hourly rate of $200 to $300 (source). Beslogic has no client reviews on Clutch yet (source), so ask for references directly. It tends to fit organizations whose custom software depends on natural language processing or private, on premises AI.
3. eXolnet
eXolnet is a Montreal firm whose Clutch profile lists a founding year of 2007, 10 to 49 employees, and custom software development as nearly all of its service focus (source). Its site lists custom software, artificial intelligence, web applications, software modernization, custom management tools, and UX/UI design (source). The firm states that its production is local and 100% in house, with no use of freelancers, and that its project managers have technical expertise (source). Clutch lists a minimum project size of $75,000+ and an hourly rate of $100 to $149 (source). eXolnet tends to fit Quebec organizations that want a custom web based management tool built and maintained by a small local team.
4. nventive
nventive is a Montreal headquartered firm founded in 2008, with a team of 250 to 999 and a 4.8 rating across 16 reviews on Clutch (source). Clutch shows its service mix weighted toward mobile app development, followed by web, AI, and custom software, with a minimum project size of $100,000+ (source). Its site groups services into custom solution development, applied AI, UX and design, support, and a modernization practice covering technology, user experience, and system integration, and it describes itself as part of Wepoint (source). nventive tends to fit larger organizations that want a mobile first custom product or a multi year modernization program from one of the bigger Montreal teams.
5. Osedea
Osedea lists Montreal as its headquarters on Clutch, with a founding year of 2011, a team of 50 to 249 people, and a 4.9 rating across 44 reviews (source). It describes itself as an innovation firm specializing in AI and custom software development, with services in digital product design, software development, artificial intelligence, robotics, and data and business intelligence, and it states that it is SOC 2 Type 2 certified (source). Mila, the Quebec AI Institute, announced a strategic partnership with Osedea in 2024 (source). Osedea tends to fit industrial, health, and mining organizations whose custom software involves AI, computer vision, or robotics.
6. Sidekick Interactive
Sidekick Interactive is a Montreal based team serving businesses across North America (source). Its Clutch profile lists a founding year of 2011, Montreal headquarters, 10 to 49 employees, and a 4.9 rating across 30 reviews, with mobile app development as its largest service line followed by custom software and web development (source). Its site lists native iOS and Android development, web apps, custom software, and UX/UI design, and highlights technically demanding areas such as IoT, Bluetooth and mesh networking, 3D scanning, AR and VR, plus maintenance, app rescue, and AI code migration services (source). Sidekick tends to fit businesses whose custom software runs on connected hardware, or who have an existing app that needs rescue or modernization.
7. Spiria
Spiria began in Montreal in 2003 and has teams in the Gatineau-Ottawa area, Montreal, and the Toronto-Oakville area, with more than 150 professionals across Canada (source). Its services include custom software development, application modernization, artificial intelligence, discovery and UX/UI design, cross-platform development, team extension, quality assurance, and support and maintenance (source). Spiria announced its SOC 2 Type 2 certification in February 2026 (source), and it holds a 4.9 rating across 27 reviews on Clutch (source). Its site describes bilingual experts and reports more than 600 clients and more than 2,000 projects (source). Spiria tends to fit established Quebec and Canadian organizations that want a long running, bilingual partner for a new build or the modernization of an existing application.
8. Uzinakod
Uzinakod was founded in 2015, has its offices in Montreal's Old Port, and says its team grew from three employees in 2018 to more than 70 today (source).

Its services include software development, mobile and web applications, systems modernization, automation, IT systems integration, data science, business intelligence, AI, IoT, embedded systems, and Industry 4.0 (source). Clutch lists a minimum project size of $100,000+ and an hourly rate of $150 to $199, and the firm has no client reviews there yet (source). It offers either full turnkey project delivery or a squad of experts that supports an existing IT team (source). Uzinakod tends to fit industrial, energy, and transport organizations that need custom cloud software and data work from an ISO 27001 certified Montreal team.
What custom software costs in Montreal
Montreal rates sit in a wide band, and the Clutch profiles of the firms above show it. eXolnet lists an hourly rate of $100 to $149 (source), Uzinakod lists $150 to $199 (source), and Beslogic lists $200 to $300 (source). Minimum project sizes are just as varied, from $10,000+ at Beslogic (source) to $100,000+ at nventive (source). These are list figures, not quotes, and the final price depends on scope, integrations, and how much of the work your own team handles.
For a fair comparison, ask each firm to price the same scoped first release and to explain what is included: discovery, design, QA, hosting, and support after launch. Our breakdown of software developer rates in 2026 covers ranges by role and region, and our guide to app development cost in 2026 explains how budgets break down.
Why buyers choose a Montreal team
- Bilingual delivery. Montreal firms can usually run a project in French and English, which matters for Quebec users, staff, and public sector buyers.
- Eastern time zone. A Montreal team works the same hours as Toronto, New York, and Boston, which keeps feedback loops short for Canadian and US East Coast buyers.
- AI depth. Several firms on this list, including Beslogic, Osedea, and Uzinakod, put AI and data science at the centre of their custom work.
- In person access. A local partner makes workshops, user testing, and steering meetings easier during the riskiest phases of a build.
A short buyer guide
- Shortlist three firms whose case studies match your type of software, and call one reference for each.
- Meet the people who will do the work, and confirm whether any of it is subcontracted.
- Check French capability in the statement of work if you need French interfaces or documentation.
- Ask for security documents such as a SOC 2 report or ISO 27001 certificate if your customers will review the vendor.
- Settle ownership early: IP assignment, repository access, and hosting accounts in your name.
- Start with discovery or a first release before signing a long contract.
Methodology note
We built this list from publicly verifiable information: each firm's own website and its Clutch profile, plus Montréal International for the talent figures and Mila's announcement for Osedea. We started from the firms that AI assistants most often name for custom software development in Montreal and kept only firms headquartered in Greater Montreal. Every factual claim links to its source. Ratings, review counts, and rate bands are as shown on Clutch when we checked in October 2026 and change over time; two firms here have no Clutch reviews yet, and we say so rather than guess. We did not invent ratings, scores, or superlatives. Confirm current details with any vendor before you sign.
The right custom software development company in Montreal depends on what you are building: on premises AI, connected hardware, a mobile first product, a custom management tool, or a full platform that has to integrate with the rest of your systems. Shortlist two or three firms, verify the facts, and start with a scoped first release. If you want to talk through a custom build, see our product development and enterprise software services, or talk to our team.
