What we build for you
Five ways to put AI to work in your business. Each one scoped, built and shipped with a smile.
AI Development
Custom AI applications built for your workflows: LLM products, internal tools, document intelligence, search and retrieval. Production grade, not prototypes.
AI Automation
Workflows that run themselves: invoicing, reporting, support triage, data entry. Hours back every week.
AI Agents
Autonomous agents that research, decide and act, with guardrails, observability and human oversight built in.
AI Strategy
Honest, vendor neutral advice on where AI actually helps, and a roadmap you can execute with or without me.
Integrations
AI wired into the systems you already run: CRM, ERP, email, APIs. No rip and replace.
Process
Four easy steps
Small scopes, fast feedback, working software early. No six month discovery phases.
Find the leverage
A short discovery call and workflow audit. We find where AI saves the most time or unlocks the most value.
Working prototype
Within one or two weeks you test a real prototype on your real data, before committing to a full build.
Ship to production
Hardened, tested and integrated with your systems. Security, cost controls and monitoring included.
Improve continuously
Optional retainer: monitoring, model updates and new automation as your needs grow.
Products
My own products and tools
What I build outside client work. Some are in development; the cards say which.

FAQ
Common questions
How do we get started?
A free 30 minute call. You describe the problem, I tell you honestly whether AI helps, and what the smallest useful first step looks like.
What does a project cost?
Sprints are fixed price. Builds are quoted after scoping, typically in the range of a mid-size development project. You always know the number before we start.
Is our data safe?
Yes. EU hosted options, data processing agreements, and architectures where sensitive data never leaves your infrastructure when that is a requirement.
Do you work with agencies?
Yes, as a white label AI partner or embedded specialist on client projects. Swedish speaking clients are served through Bergsten.net.
What if the prototype shows AI is not worth it?
Then I tell you that, and you have spent two weeks finding out instead of six months. The sprint report is yours either way.
