Software Development
Web, mobile, and full-stack product engineering. Clean, maintainable systems built by senior hands and shipped on real timelines.
Software & AI Studio
Find your bearings.
Then ship the summit.
39West is a software development and AI consulting studio. We chart the route, build the product, and get it into the world.
What we do
Three disciplines, one outfit. From the first sketch to a product in production.
AI Consulting
LLM applications, agents, and automation — plus the strategy to know where AI actually earns its keep and where it doesn't.
Product & Platform
Architecture, cloud, and the path from idea to ship. We help you build something durable, not just a demo.
How we work
We're a small, senior studio. That means you talk to the people doing the work, decisions are made quickly, and the focus stays on shipping something real instead of polishing a roadmap forever.
-
Senior by default
Experienced engineers and builders on the work itself — no hand-offs to a junior bench.
-
Ship-focused
We optimize for working software in front of users, not artifacts that sit in a drive.
-
Pragmatic
The right tool for the terrain. We pick boring, reliable choices where it counts and reach for new ones where they pay off.
Built by 39West
Compass
A roadmap tool for organizing issues into epics and shipping across milestones.
WeaveNotes
AI note-taking that connects ideas instead of just storing them.
Let's chart the route.
