Contact Us →What kinds of software do you build for Montreal businesses?
Web and mobile applications, client and employee portals, custom APIs, and full SaaS platforms — from UX/UI design through DevOps, built as production-ready systems, not one-off prototypes.
What technologies do you build on?
We choose the technology based on the project, but we commonly deliver on Microsoft Azure, AWS, and Microsoft 365 — the same platforms your Montreal team likely already uses.
Do you handle UX/UI design, or just the code?
Both. Every project includes user research, prototyping, and interface design before development.
We're not a tech company — can you still build our software?
Yes. Most of our Montreal clients aren't technical. We design every project around your real users and existing systems — ERP, CRM, Microsoft 365 — not a system your team has to learn from scratch.
What happens after the project launches?
We don't disappear after go-live. Continuous deployment, monitoring, and support are part of the engagement for every Montreal client.
Is our data secure during development?
Yes — every project follows the same security standards as our managed IT and compliance services, including enterprise-grade authentication through Microsoft Entra ID.
