I build AI systemsthat do the workyou'd rather not.

I work with fast-moving companies that have real technical problems. I build things that run in production, not demos that live in slide decks.

02About

Built by someone who's done it.

Simon Harrysson

I'm Simon, 23. I wrote my first Java program at 13, had my first app on the App Store at 14, and haven't been able to stop since. I study CS and ML in Linköping and build AI systems in the time between lectures. There's always a problem running somewhere in the back of my head. On a run, between lectures, right before sleep.

03Live demos

This is what I actually build.

Real examples of the systems I build for clients. Try them yourself.

01

Scheduling Agent

Reads your inbox, checks your calendar, and drafts a reply. You don't lift a finger.

02

Live Automation Analysis

Enter your website URL. Three Claude agents analyze your business, map the manual workflows, and calculate exactly how many hours and dollars you're leaving on the table.

03

ROI Calculator

See exactly how many hours and kronor your team could recover by automating repetitive work.

These are representative demos. Production systems are customised to your stack, data, and workflows.

04How it works

No pitch. Just a conversation.

We'll spend 30 minutes looking at your work together and figure out what makes sense to automate.

1

Book a slot

Pick a time that works for you. No prep, no forms, no brief to fill out beforehand.

2

Walk me through your work

Tell me what a normal week looks like. We find the tasks that eat time and shouldn't need a human.

3

You decide what happens next

If there's a clear fit, we scope it out together. If there isn't, you've lost 30 minutes and gained a bit of clarity.

05Book a call

Let's find 30 minutes.

Pick a 30-minute discovery call if you have a project in mind, or a 15-minute intro if you just want to get a feel for whether I'm the right fit. No prep needed.
