About us
A family collective with engineering at its core
SPAR Collective LLP is a family-run engineering firm rooted in embedded systems, industrial automation, and IoT. We don't build demo-ware. We engineer for deployment, and every board is built to perform where it matters: the factory floor, the substation, the field.
