History of Muthokinju Paints & Cement
Muthokinju Paints & Cement was founded in 1995 in Kasarani, Nairobi, by business couple Susan Muthoni Kimani and Barnabas Njuguna.
The company’s name was created by combining parts of the founders’ names: “Mutho” from Muthoni, “Ki” from Kimani, and “Nju” from Njuguna.
Before venturing into the hardware business, the family had operated a restaurant at Kenyatta Market, Ngumo Estate.
The family later decided to shift to the construction materials sector, believing it offered more sustainable opportunities than selling perishable goods, after experiencing losses in the Hotel business.

The decision led them to establish a small hardware shop selling paints, cement, and building supplies.
The business steadily grew as demand for construction materials increased in Nairobi and surrounding towns.
Over the years, Muthokinju expanded its product range to include paints, adhesives, cement, and decorative materials, which it supplies through partnerships with major manufacturers, and now employs more than 200 people.
In 2004, the company was incorporated as a limited company, a move that helped formalize operations and support expansion plans. New branches were opened within Nairobi and later in other towns across the country.
When Benjamin Kimani assumed leadership, he built on the foundation established by his parents and accelerated the company’s growth.
“I wanted the business to expand more, but I realized that you need to have a structure to grow at that pace. So I slowed down and went back to creating the right structures to make that happen,” said Kimani.
Through digitization, improved logistics, and expanded retail networks, Muthokinju has grown from a single hardware store into a national distributor of building materials across the country.
