# Chisel Industries > Chisel Industries backs the skilled trades three ways: it invests in and acquires trades businesses, it builds Continuous Software — free, AI-native operating systems that run those businesses — and it reinvests in trade schools, scholarships, and apprenticeships. It is run by operators who own and operate trades businesses themselves. Chisel calls its software category Continuous Software: software that does the work rather than waiting to be filled in. The operating principle is "No Forms" — an operator speaks or texts what happened and the system handles the record, the invoice, and the collection. The software is free to trades businesses, with no per-seat subscription.
