Its product portfolio comprises four independently positioned offerings: aControl, a module software system for access control, workforce scheduling and production-based wage calculation that integrates with hardware devices from multiple manufacturers; proSmart, an IoT platform including the BBoil Wi-Fi programmable thermostat controller for home, building and industrial automation, with 32,472 connected devices reported; Audit, a web and mobile auditing system for real-time inspection creation, photo capture, signature collection and offline operation; and Supervisor360, a field service management platform launched on January 12, 2026 targeting cleaning, security and facility management operators with real-time visibility, QR/NFC/GPS proof of service delivery, and compliance tracking. The technology stack emphasizes web-based applications with mobile clients on iOS, Android, and Windows Phone, real-time data processing with encrypted transfer, and an IoT platform with cloud-connected relay modules and programmable scheduling.
DSI serves a heterogeneous customer base of 1,927 reported customers and 7,614 active users spanning small, medium and large enterprises across airports (Birmingham, Heathrow, Manchester, Newcastle, Liverpool John Lennon), financial services (Santander), telecommunications (Vodafone), media (Sky, BBC), government (Nottinghamshire Police, Scottish Parliament), automotive (BMW, Rolls-Royce, Michelin), manufacturing (Bayer MaterialScience), consumer goods (Estee Lauder, Kellogg's), and education (Sunderland College). Distribution is via direct software download for self-serve SMB adoption plus contact-based enterprise sales, with a dedicated UK product website (supervisor360.co.uk) for the Supervisor360 product. No external funding rounds, M&A activity, executive team information, certifications or patents are disclosed in the source material.
