KUBU SMART LIMITED

What KUBU SMART LIMITED does

Kubu Smart Limited is a UK-based smart home security hardware company founded in 2019 and headquartered in Rugeley, Staffordshire. It designs and manufactures concealed smart sensors, a Home Hub, and a companion mobile app that monitor the real-time security status (open, closed, locked, unlocked, vent mode, under attack) of doors and windows. The proprietary technology integrates sensors into multi-point door locks and window frames, combining micro-switch and wire-coil sensing methods, with patented clip-in fitment for windows. Its product portfolio includes the Kubu Door Sensor, the Anywhere Pro Window Sensor, the Floating Window Sensor (G23 New Product of the Year 2023), and the Kubu Home Hub, supported by the SureShield and SureSecure alert features and family-sharing capabilities via the Kubu iOS/Android app.

The company operates a hybrid go-to-market model spanning direct-to-consumer e-commerce through getkubu.com and a trade channel built on two programmes: the 'Works with Kubu' certified fabricator network (including Emplas, Nationwide Windows, Sheerline, ABS, Solidor, CompDoor, Window Ware, and VBH/GreenteQ) and the Kubu Pro Installer scheme for retrofit installations. Revenue is generated through hardware sales (sensors and hubs at unit pricing), monthly app subscription features (monitoring history, remote controls, extended sharing), insurance referral economics via the Locket partnership, and trade-margin sales to Pro Installers. The platform is integrated with Amazon Alexa, Google Home, IFTTT, SmartThings, Yale, Hive, Tado, and Ring, and Kubu holds the IASME Level 2 IoT Accreditation (a first for smart sensor manufacturers), Secured by Design Secure Connected Device certification, and PSTI/ETSI EN 303 645 compliance.

Kubu is privately held, founder-led (CEO Mark Bromley; Co-Founder Ryan Bromley), and operates as a bootstrapped UK private limited company with no disclosed institutional funding, parent entity, or acquisition activity. Its strategic focus is on scaling the fenestration partner ecosystem (uPVC, aluminium, and hardware brands), extending geographic reach across the UK and Europe, and converting the installed base of Kubu-enabled doors and windows into recurring app subscription and insurance-linked revenue.
