📋 About Kassmatt Supermarket
Kassmatt Supermarket is a Nairobi-based retail chain best known for its strong presence along the Kasarani-Mwiki-Githurai corridor and Thika Road, an area that has grown rapidly as a residential and commuter hub over the past decade. The supermarket has built a loyal local following, particularly around its original Kasarani Mwiki Road store, offering groceries, household essentials, and everyday goods “under one roof” for the surrounding neighbourhoods.
Kassmatt has expanded from its Kasarani roots to operate 5 branches across Nairobi and Thika, including its Main Branch at Jumbo, Githurai, and continues to serve the fast-growing Mwiki area. Beyond in-store shopping, the supermarket offers additional convenience services including M-Pesa transactions, gas cylinder refills, and ATM access at select branches, alongside an online shop for customers who prefer to order ahead. The company maintains an active social media presence and a dedicated customer contact channel for feedback and inquiries.

⭐ Reviews & Ratings
Kassmatt is a familiar, convenient neighbourhood option for the Kasarani-Mwiki-Githurai corridor, valued for its bakery and product variety, though independent directory reviews have raised concerns in the past around customer service consistency and communication during changes like till/paybill updates, which prospective shoppers may wish to be aware of.
“Convenient supermarket for us in Mwiki — have everything you need under one roof and the bakery pancakes are genuinely good. Prices are fair for the area.”
“The Jumbo Main Branch is well stocked and being able to do M-Pesa transactions and gas refills in the same trip saves me a lot of time during the week.”
“Had an issue with a till/paybill change that wasn’t communicated clearly and it caused confusion with a payment. Would encourage the branch to give customers a heads-up before switching payment numbers in future.”
“Good to have Kassmatt now in Thika town too — decent variety and the online shop option has been handy on weeks when I can’t get to the store in person.”
