Artificial Intelligence and Domestic Sovereignty for the Modern Era
xstrat is a Canadian AI consultancy. We design, build and support AI and IT solutions for small businesses, and we help them keep their data and technology under Canadian control.
Transform your data. Empower your strategy. Drive your growth.
One consultant who has run mission-critical systems
xstrat is led by David Signoretti, a product manager and solutions architect with more than twenty years in Ontario emergency healthcare technology. The same discipline around uptime, privacy and requirements goes into every small business project.
Domestic Sovereignty
Keep your data, tools and decisions under Canadian jurisdiction, and reduce reliance on US technology.
02 TrainingAI Training
Hands-on training so your team uses AI and large language models in their daily work with confidence.
03 IntelligenceAI-Powered Intelligence
Custom AI agents and retrieval systems that answer questions from your own data.
Move away from US technology
Where your data lives and who can reach it is a business decision. We help you make it on purpose.
Know what you depend on
We map the software, hosting and AI services your business relies on and show where your data is stored and who controls it.
Plan the move
We recommend Canadian-hosted or self-managed alternatives that fit your budget, then plan the migration so daily work is not interrupted.
Govern the data
Database administration on SQL Server, MySQL and PostgreSQL, with data governance practices that protect security and integrity.
Your team, working confidently with AI
Tools only pay off when people use them well. We teach practical habits, not theory.
Customized learning paths
Training built around your tasks and your workflows, so staff learn on the work they already do.
Proven training methodology
David created and ran formal certification curricula for Ontario's air ambulance communications officers, and applies the same structured approach to business teams.
Safe use of LLMs
Clear guidance on what to put into an AI tool and what to keep out, based on real privacy and cybersecurity practice.
AI that works from your data
From first concept to deployment, we design, implement and support AI solutions made for your business.
Retrieval-Augmented Generation
xstrat built a RAG framework on healthcare FHIR data to improve the accuracy and relevance of LLM answers. The same approach lets an agent answer from your documents and records.
Integrated with your systems
Experience with FHIR and HL7 integrations, APIs and SQL means agents connect to the systems you already run.
Supported after launch
We monitor cybersecurity trends and evaluate new technology so your solution stays secure and current.
