Kiefer Sage is an innovative ecosystem of our owned brands, client products and manufacturing.

From one invention in a garage to a family of purpose-driven brands, we build solutions that matter.

We create businesses that serve overlooked and undervalued markets. Every brand we grow is purpose-built and people-powered—designed to make life safer, easier, and more independent.
