Share911

What Share911 does

OnScene Technologies, doing business as Share911, is a privately held, cloud-based emergency communication platform founded in 2013 and headquartered in Ramsey, New Jersey. The company builds software that, in the moment an emergency is reported, simultaneously alerts the people in proximity to the incident and the responding agencies — 911 dispatch, police, fire, and EMS in the United States (Share911) and 999-led emergency services in the United Kingdom (Share999) — with the same critical information. The product architecture runs entirely on existing endpoints (phones, tablets, computers) without hardware installation, panic buttons, or new network buildout, leveraging proximity detection and location sharing to close the timing gap between emergency reporting and notification of people nearby.

The product portfolio has four components: Share911 and Share999 as the regional subscription platforms, Share911 Instant as a no-app, QR-code-based variant enabling frictionless per-event and dormant in-room deployment for crowds at events, hotels, malls, transit, airports, buildings, and construction sites, and ReunifyMe as a sub-product for post-incident reunification workflows. Target verticals span K-12 education (Alyssa's Law compliance for panic buttons and emergency notification), higher education, commercial and enterprise workplaces (California WVPP/SB 553 compliance), venues and events, healthcare, government (Martyn's Law and JESIP interoperability in the UK), faith-based organizations, and public safety.

The business operates a dual go-to-market: enterprise field sales with Calendly-driven demos and annual subscription licensing for Share911/Share999, paired with self-serve product-led growth and usage-based per-event pricing for Share911 Instant. The company is bootstrapped, with no disclosed funding rounds, no M&A activity, and no institutional ownership changes across its 13-year operating history. Marketing is built around a compliance content hub (Alyssa's Law by state, Martyn's Law, JESIP, California WVPP), incident case studies under the brand "The Gap," and a LinkedIn presence operated as OnScene Technologies. US and UK phone support lines are publicly listed, and a 2026 website copyright indicates ongoing operations.

Core offering

Share911 (US) and Share999 (UK) are cloud-based, real-time, multi-agency emergency communication platforms that deliver a single incident report simultaneously to people in harm's way and to responding agencies (911/999 dispatch, police, fire, EMS). Share911 Instant adds a no-app, QR-code-based emergency alert system for crowds at events, hotels, malls, transit, buildings, and construction sites, with ReunifyMe handling post-incident reunification. The entire platform runs on existing phones, tablets, and computers with no hardware installation and is positioned around compliance with Alyssa's Law, Martyn's Law, California SB 553, and JESIP.

Product overview

OnScene Technologies operates a unified emergency communication platform with two regional core products: Share911 for the US market and Share999 for the UK market. Both deliver real-time, multi-agency emergency alerts that simultaneously inform people on-site and dispatching agencies. The Share911 Instant module provides a no-app, QR-code-based variant for rapid site-wide deployment without friction. ReunifyMe, referenced as a platform feature, handles emergency reunification scenarios. All products work on existing devices (phones, tablets, computers) with no hardware installation required, and the platform supports compliance with regulations including Alyssa’s Law, Martyn’s Law, and California SB 553.

Direct peers

• Singlewire Software: Singlewire's InformaCast is a mass notification platform widely deployed in K-12 and higher education for emergency alerts, panic buttons, and IP-speaker integration. It competes head-on with Share911 in the same school and campus segments and represents the legacy on-premise-leaning alternative.
• Regroup Mass Notification: Regroup is a mass notification SaaS targeting higher education, healthcare, government, and enterprise — directly overlapping with Share911's vertical segmentation and the same compliance-driven buying cycles.
• Omnilert: Omnilert (formerly e2Campus) is a long-standing emergency notification platform focused on higher education, K-12, and enterprise. It addresses the same multi-channel alerting and panic-button use cases that drive Share911's K-12 and higher-ed value proposition.
• Rave Mobile Safety (Rave Alert): Rave is one of the most direct comparables — a mass notification and emergency communication platform serving K-12 schools, higher education, workplaces, and 911/ECC centers in the US. It addresses the same core use cases (panic button/notification, multi-agency alerting, Alyssa's Law compliance) and competes for the same institutional buyers.
• AlertMedia: AlertMedia is a closely comparable mass communication and emergency notification SaaS platform targeting the same mid-market and enterprise segments (workplaces, schools, healthcare). It offers two-way mass notification, threat intelligence, and similar mobile-first deployment, making it one of Share911's most direct US peers.

Broad incumbents

• Motorola Solutions: Motorola Solutions is a major incumbent in public safety communications, with CommandCentral, radio, and CAD products used by PSAPs and first responders. It is adjacent rather than direct — it owns much of the downstream 911/999 infrastructure that Share911 integrates with, and could move upstream into citizen-facing alerting.
• Crisis24 (GardaWorld): Crisis24 (and its Send Word Now acquisition) provides enterprise mass notification alongside broader security services, threat intelligence, and executive protection. It competes with Share911 at the high end of the enterprise and government market with a much wider portfolio.
• Everbridge: Everbridge is the dominant public-company incumbent in Critical Event Management and mass notification, with a much broader portfolio spanning IT alerting, travel risk management, and public warning. It overlaps with Share911 on enterprise and government emergency communication but operates at far greater scale and breadth.
• Cisco (Webex, emergency notification integrations): Cisco's collaboration and IoT platforms are increasingly used for facility-wide alerting and notifications in enterprises. While not a dedicated emergency comms vendor, its installed base in workplaces and education represents a bundling threat to standalone platforms like Share911.
• Honeywell (Notifier / Connected Life Safety): Honeywell's life safety portfolio (fire alarm, voice evacuation, mass notification hardware and software) overlaps with the building-side of Share911's use cases. It represents the legacy hardware-heavy incumbent in emergency communications for commercial buildings.
