Norway · Independent software
Software, built small and shipped.
Sombrero Holding AS is the company behind a handful of small, sharp products — strength training, running, golf, padel, music, and party games.
One person, end to end — no outside funding and no roadmap by committee. Each of these exists because something was annoying enough to go and fix, and sticks around because people use it.

Pacer
LiveA pace calculator that doesn't suck.
Splits, grade-adjusted pace, and a personal pace-vs-grade curve fitted from your own Strava history — so the numbers match the hills you actually run.

Americano
LivePadel tournament scoring.
Name the tournament, drop the players in, pick your courts. Rounds generate themselves, the pairing engine remembers who has played with whom, and standings update live over WebSockets.

Lifter
LiveStrength training that follows you out of the gym.
One program, three rooms — gym, home, CrossFit. The coach reads your strength curve, works around your injuries, and talks back.

Queued
LiveThe party queue, without handing over the aux.
Everyone in the room adds to one shared Spotify queue from their own phone. The host keeps control of playback; on web the browser tab itself becomes the speaker.

Scramble
In developmentGolf scoring for the group chat.
Live scorecards for scramble, stableford, and matchplay, on top of course geometry imported from OpenStreetMap — distance to green and hole maps without hand-typing a single slope table.

Parlor
PrototypeAI-hosted parlor games.
Werewolf, hosted by a model that never breaks character and never peeks at the wrong card. Phones are the players, the TV is the table.
02 Who
Jesper Paulsen
Software engineer
I build products end to end — the data model, the API, the app, the landing page, and the pipeline that ships it. I like small teams, short feedback loops, and software that does one thing well enough that you notice.
Most of what is listed here started as a personal annoyance: a pace calculator that got the hills wrong, a padel tournament run on a napkin, a party where someone had to hold the aux cable all night.

03 Day job
The AI GIS for modern teams.
By day I'm a software engineer at Atlas — a browser-based mapping and spatial analysis platform where the map gets built from a conversation rather than from a desktop install and a semester of training.
It's used by energy developers, asset managers, field operations teams, and municipalities — places where the land team, the engineers, and leadership all need to be looking at the same map.
- Describe what you need and Navi, the AI assistant, builds the map
- Spreadsheets, databases, and standard GIS formats side by side
- Analysis, dashboards, and reporting that stay live as the data changes
