Communication, safety, equipment tracking, workforce compliance, and engineering calculations. From construction sites to hospital wards.
Mesh relay hardware and site dashboard.
Offline mesh messaging for construction. Free.
Workplace communication and safety. Free.
Most workplaces run on a patchwork of tools that were never designed to work together. Gridmark builds the connected layer underneath — communication, safety, tracking, and compliance in one ecosystem.
SiteTalkie creates a Bluetooth mesh on construction sites where nothing else works — through concrete, steel, and basements. WorkTalkie brings the same platform to every other industry over WiFi — hospitals, warehouses, retail, schools, hotels. Both are free. SiteNode extends coverage with permanent relay hardware and a site-level dashboard. SiteChip tracks shared equipment with NFC tags — tap to check out, no app needed. SiteCreds gives every worker a qualification wallet for Building Safety Act compliance. And MEP Desk provides 61 verified engineering calculators sourced against UK standards.
Every product shares a single identity system. Every product is designed for the people who actually do the work.
