Their Moja (free public WiFi) platform was launched in June 2018 and already has more than 250,000 users in both Kenya and Rwanda. BRCK is the only company in East Africa that has a full stack of engineering for products, as well as in-house design, user experience, and product management. Since 2013, the company has created the original BRCK v1, the Kio Kit for education, the SupaBRCK for enterprise connectivity, computation, and storage, and the PicoBRCK for rugged IoT needs. Besides designing circuit boards and ruggedized cases, the team also writes the firmware, operating systems, and cloud stack of software that allows all of its devices to be remotely managed.

In 2019, BRCK acquired Surf, another internet provider, becoming the largest public WiFi network in sub-Saharan Africa.
