About Mitch Hagstrom & Thornline Labs
I built the apps I wanted to use. The kind that do one thing well, look great doing it, and don't waste your time.
Mitch Hagstrom — Founder, Thornline Labs. Built in Ohio.
Precision over excess.
We believe the best software does less, better. Every app starts with a sharp problem and ends with a refined solution. No feature bloat. No visual clutter. Just thoughtful design meeting deliberate engineering.
The pipeline
One thing at a time, done properly.
Thornline builds a small number of products and gives each one full attention. Swappr has ours today. The next one is already underway.
Ohio first
