About
ThreadCraft Labs is a Milwaukee studio building local-first hardware and software. The flagship is Linden, an air monitor and purifier with a friendly e-ink face and no cloud. Alongside it is a family of small, honest software tools. The throughline is simple: build things that earn their place in a home and keep working for years, with your data staying on your own devices.
