Speed, ROI and a team that scales with you
North American teams care about getting to market fast and proving return on investment. We focus on a production launch in weeks and measurable results after it.
Production in 25 to 30 days
A real, launchable first version in about a month, so you can sell, raise or learn sooner.
Senior talent, lower burn
Senior engineers at typical rates of $25 to $49 per hour, without recruiting costs or long notice periods.
Built to scale
Cloud architecture, automated tests and CI/CD from day one, ready for your next growth stage.
Security and compliance ready
HIPAA-trained team, HL7/FHIR experience, and security practices that fit SOC 2-style questionnaires.
What we build with LLMs
Custom LLM applications
Assistants, copilots and internal tools built around your workflows, not a generic chat window.
LLM integration
Add GPT, Claude or Gemini to your existing product through secure, well-tested APIs.
Open-source and private models
Deploy Llama and other open models on your own cloud when data must stay in-house.
Fine-tuning and evaluation
Tune models on your examples and measure accuracy with test sets before and after launch.
Guardrails and safety
Input and output filtering, PII masking, grounding checks and human review where needed.
Cost and latency optimisation
Model routing, caching and prompt design that keep responses fast and bills predictable.
How we approach LLM development
Choosing the right model
There is no single best model. We compare OpenAI, Claude, Gemini and open-source options on your real tasks for accuracy, speed, cost and data handling, and design the app so the model can be swapped later without a rewrite.
Grounded in your data
Most business value comes from connecting the model to your documents, databases and tools. We use retrieval (RAG), function calling and agents so answers come from your information and actions happen in your systems.
Built for production, not demos
We add evaluation test sets, logging, monitoring, rate limits, fallbacks and cost alerts from day one, so the app keeps working well after launch and you can see exactly what it is doing.
Security and compliance
Data minimisation, encryption, access control and providers configured not to train on your data. For healthcare we build to HIPAA requirements with BAAs in place for any service that touches PHI.
Remote, but close to Montreal
Time-zone overlap
Our team overlaps with US Eastern mornings and runs flexible evening shifts for a live daily stand-up, so you get same-day answers and progress waiting each morning.
PIPEDA and provincial privacy laws
We build to PIPEDA principles (consent, limited collection, safeguards and access), keep data in Canadian cloud regions when required, and sign NDAs and data agreements before work starts.
Billing
Invoices in Canadian dollars (CAD) or US dollars. Typical senior rates are $25 to $49 (USD) per hour, or a fixed price for a defined scope.
Industries we work with in Montreal
Montreal companies work with us on AI products and SaaS, including bilingual English and French interfaces, with privacy designed for Canadian requirements.
Natural resources and energy
Mining and oil firms digitise field operations and reporting. We build AI agents, assistants and automation around these workflows.
Financial services
Major banks and fintechs modernise digital banking. AI here usually means faster reporting, fewer manual steps and better customer replies.
AI research and tech
Strong AI ecosystem fuels startups shipping ML products. We start with one costly process and automate it end to end.
Agriculture and food
Farm and food producers adopt supply-chain and traceability tools. We build AI agents, assistants and automation around these workflows.
