- Swift & Kotlin
- App Store & Play Store
Software studio · Montreal
We build mobile and web products, from first sketch to launch.
MAD Concepts is a three-partner software studio in Montreal. Founders and teams hire us when they want senior engineers on the product itself, not a large team with a project manager in between.
- Montreal, Quebec
- Three partners
- 30+ years combined
Services
Mobile, web, and the cloud behind them.
Most projects touch all three. We can own the whole thing, or take one part and work alongside your team.
Web platforms
Marketing sites, dashboards, storefronts, and internal tools. Fast, accessible, and easy for your team to maintain.
- Next.js & React
- Shopify & headless commerce
- Dashboards & admin tools
Cloud & backend
APIs, databases, real-time systems, and infrastructure as code. Auth, billing, and monitoring wired in from the start.
- Node.js & PostgreSQL
- AWS & Vercel
- WebSockets & real-time
We reach for proven tools before new ones. Boring usually ships faster, and it’s easier to hire for later.
Something you can try
Try what we built.
The Arena is a real-time multiplayer party game we built and run ourselves. Friends join with a four-letter code, vote on one of about twenty mini-games, and play a few rounds together. It runs on WebSockets and a single small server, with the same stack we use for client work.
- Real-time over WebSockets
- 2 to 6 players per room
- Runs on one small server

How we work
From a first call to a launch, in weeks.
Most of building software is unglamorous: error states, edge cases, deployment, monitoring. We give those the same care as the parts people see.
- 01Week 1
Discover
One or two calls to understand the problem and what success looks like. You get a scope memo, a timeline, and a budget range.
- 02Weeks 2 to 3
Blueprint
Architecture, data model, key screens, and technology choices, written down so the reasoning outlives the project.
- 03Two-week sprints
Build
Working software at the end of every sprint, deployed to a staging environment you can use.
- 04Plus 30 days
Launch
Production deployment, store submissions, monitoring, and a runbook. We stay on for 30 days after launch.
A typical engagement runs 6 to 14 weeks, in two-week sprints, with a working demo at the end of each one.
Who you’ll work with
Three partners. That’s the whole team.
MAD is the three of us. Every project is staffed by the partners, from the first call through launch. There’s no handoff to a delivery team after you sign, because there isn’t one.
Systems & cloud
APIs, databases, real-time servers, and the infrastructure that runs them.
Product & front-end
Product design and front-end engineering. Rough ideas into prototypes, prototypes into shipped interfaces.
Mobile & real-time
React Native, native iOS and Android, and the WebSocket layer that ties them to a server.
