About The Company

We are an early-stage, venture-backed company building modern workplace safety infrastructure, where real-time location, AI-native software, and rugged IoT hardware converge to detect issues and deliver help exactly when and where it is needed. Founded in 2024 by a team drawn from leading consumer hardware, technology, and physical-security companies, we already protect schools, universities, and frontline workplaces nationwide, with 10+ live paying customer sites. We are backed by top VCs and closing our Series A, going after a $30B market growing roughly 20% annually that is still dominated by legacy players.

• Improving core infrastructure to keep the system live and performant.
• Integrating new customers onto the platform.
• Interfacing with customers to understand their needs and translate them into product solutions.
