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.
what we do
In 1983, a simple idea to help our founder’s grandmother shop independently sparked the world’s first electric shopping cart. That garage invention became Martcart™, a brand that now helps millions of people keep moving with dignity and independence.
When cleaning challenges demanded something faster and safer, we created Spraymaster™—the first central pressure-washing system. Its smarter design makes industrial and commercial cleaning more efficient, from grocery stores to animal shelters and beyond.
Jotto Desk™ was born from the real needs of first responders, creating vehicle outfitting solutions that improve safety, efficiency, and organization in the field. Today, it’s a trusted partner for law enforcement and emergency services across the country.
Alongside our owned brands, we collaborate with companies to co-assemble and scale their innovations. With decades of experience, we provide the innovation, precision, and care needed to move products to market.
Together, these businesses form an ecosystem of innovation—rooted in empathy, built for impact, and always moving forward.
