Callsign North is a two-person development studio based in Quebec, Canada. We're senior developers with years of experience in both agencies and product teams, across healthcare, retail, finance, sports and entertainment.
We started the studio to deliver agency-level quality without the agency overhead. No account managers, no juniors: you work directly with the two developers building your product.
What we build:
- Mobile apps for iOS and Android
- Web platforms and SaaS (client portals, back-offices)
- APIs and backends
- Integrations between your existing systems
- Internal tools
- AI integrations and MCP servers connecting your systems to ChatGPT, Claude and other agents
Greenfield or brownfield:
We take new products from scoping and architecture to a production-ready first version built to grow. For existing products, we start with a code and architecture audit, stabilize, then modernize step by step while shipping new features.
How we work:
AI agents speed up the repetitive work, but every change is reviewed by one of us and covered by automated tests, and nothing ships to production without our approval. Every engagement includes tested code, documentation and a clean handoff. The code is yours.
Pricing:
CAD 15,000/month for both developers, taxes extra. No hourly billing, no long-term commitment: pause or stop month to month. After the first call, we estimate how many months your project will take.
We work in English and French, on Eastern Time, with clients across Canada and the US. Canadian hosting options available.
