IT consulting · AI engineering
Seasoned IT consulting, now building with AI.
Sustyne has spent years helping organizations design, build, and run the systems their work depends on. Today we bring that same rigor to AI engineering, shipping practical, production-grade intelligence, not hype.
Why Sustyne
A consultancy that ships.
We pair an established IT track record with hands-on AI engineering, so you get judgment and working software.
Senior, hands-on
The people who scope your project are the ones who build it. No layers, no handoff to a junior bench.
Pragmatic AI
We deploy AI where it earns its keep, measured against real outcomes, not demos.
Built to run
Years of operating production systems means we build for the day after launch, not just the launch.
What we do
Two practices, one team.
AI Engineering
LLM applications, agents, and intelligent automation, designed, built, and shipped into production with the same discipline.
- LLM apps & conversational products
- Agents & workflow automation
- RAG, evals & AI infrastructure
