Teams build with
Remember LAN parties?
A room full of people who hauled their machines across town to build something together. Nobody had to be there. They wanted to be. Being in the same room was the whole point.
That sense of community is back. Building is something you do with other people again.
Because the best code, like the best raids, gets shipped at 3am next to your friends.
Bring
Your laptop. We bring the rest.

Example challenges
The real problems are revealed on the day. Here's what they might look like.
An app that tracks promotional performance in real time
A beverage company runs promotions across 200+ stores but can't see what's working until the campaign is over. Build an app that ingests sales data and uses AI to surface which promos are driving volume while they're still running.
An automated process that unifies fragmented operations data
A facilities company manages thousands of contracts across spreadsheets and legacy systems. Build an automated pipeline that pulls it all together into one dashboard so operations managers stop digging through email chains.
An AI tool that predicts equipment failures before they happen
A logistics company has sensor data but no way to act on it. Build a tool that analyzes patterns and flags equipment likely to fail in the next 72 hours, turning raw data into a maintenance schedule.
What you win
Mac Mini + 10.000 kr + 3-month pilot
Cash prize, hardware, and your solution goes into production at the sponsoring company. Tandem supports the deployment for 3 months.
Mac Mini + 5.000 kr
