Callmy

What Callmy does

Callmy Ltd is a UK-based private technology company founded in 2014 by Tony Watson and headquartered in Lutterworth, Leicestershire. The company provides Callmy Alert, a cloud-based mass notification and lone worker security platform built on Microsoft Azure, approved to NCSC OFFICIAL classification, with ISO 27001-compliant data centres, AES-256 encryption at rest, TLS in transit, and an API-first architecture integrating fire alarms, CCTV, X-ray scanners, and enterprise systems. The platform delivers up to 2,000 encrypted messages per second across iOS, Android, and Windows apps, with geo-targeting, critical-alert override of silent/DND modes, GPS location tracking, man-down detection, live audio streaming, and 24×7 NSI Gold BS8484-certified Alarm Receiving Centre monitoring. Callmy holds BS 8484:2022, ISO 27001, Cyber Essentials Plus, GDPR, and BS9518:2021 certifications, and is a Crown Commercial Service G-Cloud 12 and 13 supplier.

The business operates a hybrid go-to-market combining direct enterprise sales with a multi-tier channel network. Peoplesafe resells the service under the "Peoplesafe Alert" brand (e.g., a 12,000-staff HCA Healthcare UK deployment), Kings Secure Technologies / Cougar Monitoring provide NSI-certified ARC monitoring and resale, and integration partners (Todd Research, Monitor Computer Systems/Sentinel, QuidvisRisk) co-sell into security and risk-management ecosystems. Revenue is generated through annual SaaS subscriptions (often organisation-wide rather than per-seat), managed ARC monitoring add-ons, dedicated lone worker hardware sales, and premium SMS broadcast add-ons. The customer base spans UK central and local government, NHS, education, financial services, healthcare, retail, manufacturing, emergency services, and culture/heritage, with named logos including NHS, HMRC, Nasdaq, Merseyside Fire and Rescue, and multiple UK universities. The company has reported a third consecutive year of growth, driven by rising security risks and regulatory demand from Martyn's Law and the upcoming Cyber Security and Resilience Bill.

Revenue model

1. SaaS Subscription (Mass Notification & Lone Working): Annual or multi-year subscription for access to the Callmy Alert platform including mass notification, SOS/lone worker safety features, management portal, and reporting. Customers can choose between self-managed (in-house control room) or managed service (ARC-provided 24×7 monitoring) options. Pricing is organisation-wide rather than per-seat for some tiers.
2. Managed ARC Monitoring Service: BS8484-certified 24×7 Alarm Receiving Centre triage of SOS activations. Offered as an add-on to the core subscription, delivered in partnership with NSI Gold-certified ARC (Cougar Monitoring). Staff are security-screened to BS7858 and authorised to mobilise emergency services nationally on behalf of third parties.
3. Lone Worker Hardware Device: Dedicated lone worker device sold alongside or separately from the app-based service. Discrete hardware with panic button, man-down, and location tracking capabilities, monitored via the ARC service. Represents a hardware sales revenue stream for customers preferring or requiring a dedicated device over a smartphone app.
4. SMS Broadcast (Premium Add-on): Carrier-class SMS gateway enabling message delivery to users without the app installed (e.g., visitors, temporary contractors). Messages delivered at 1,000 per second with high resilience. Serves as a fallback communication channel and supports Martyn's Law visitor notification requirements. Billed as a premium add-on to the core subscription.
