The team behind LMK Software
Joar Lennermark
Founder · Growth & strategy
Joar has spent a long time inside growing businesses. He helped scale a door-to-door sales operation from €6k to €1M per month, and has been involved in enough organizations to see exactly where time and money leak out.
He's focused on figuring out which workflows actually move the needle — what's worth automating, what's worth rebuilding, and what's fine as a spreadsheet. He cares about ROI, not novelty.

Noah Stahlhacke
Technical lead · Systems & architecture
Noah has deep experience across full-stack software and the infrastructure that keeps modern products running — from the interfaces customers use every day to the systems quietly holding it all together.
Noah contributes to how the product is built — from architectural decisions and tool selection to overall code quality. Clean architecture, boring reliability, no surprises in production.
