HardHat Pulse Closes Seed Round to Expand Construction Safety AI Platform
The funding will support hardware production scale-up, Procore and Autodesk ACC integration depth, and expansion into Gulf Coast industrial markets...

Why Construction Fatality Rates Haven't Improved in 15 Years — And What's Different Now
BLS data from 2010 to 2024 shows the fatal injury rate in construction declining just 11% — far behind improvements in manufacturing and warehousing. The gap is measurement, not effort...
PPE Detection Accuracy on Active Jobsites vs. Controlled Benchmarks: What the Gap Actually Is
Most published computer vision benchmarks for construction PPE detection use curated datasets photographed under controlled lighting. Real jobsite performance is lower — here's the data...
Edge Inference vs. Cloud: Why Sending Video to AWS Isn't a Safety Strategy
A 400ms round-trip to an AWS region sounds fast in web development. On a construction site where a worker is entering a crane swing radius, it's 400ms too slow...
How We Geo-Fence Danger Zones That Change Every Day
Crane swing radii shift as lifts are repositioned. Excavation edges grow. The hard part of dynamic zone management isn't drawing polygons — it's keeping the site model in sync with what's actually happening on the ground...
Wearable Sensors in Construction Safety: What BLE Gets Right That GPS Gets Wrong
GPS accuracy on a dense urban jobsite — surrounded by glass towers causing signal multipath — is between 3 and 8 meters. That's not enough precision to determine if a worker is inside or outside a 2-meter exclusion zone...
OSHA 300 Log Automation Isn't Glamorous — It's What Site Safety Managers Actually Need
Every GC we've spoken to during sales calls mentions the same operational friction: OSHA 300 entries are filled in at the end of the week from memory, incident notes, and whatever the foreman's app captured. That's not a compliance problem, it's a data problem...
Integrating Safety Detection Data Into Procore Without a Custom Dev Project
Procore's API is well-documented, but most construction companies don't have in-house developers to wire it up. Our Procore integration ships as a one-click app marketplace install — here's what it actually syncs and what it doesn't...
Heat Stress Is the Leading Unreported Cause of Construction Incidents in the Gulf Coast
OSHA recordable incident logs capture fractures, lacerations, and struck-by events. They frequently miss the heat stress episode that preceded the fall or the impaired judgment that led to the equipment contact...
What AI Safety Monitoring Can't Do — An Honest List
We sell a computer vision system. We should be clear about what it misses. Camera occlusion, adverse weather, novel PPE variants, and situations that require human judgment are all failure modes we've documented in pilot deployments...
Fall Detection From a Hard Hat Clip: Accuracy vs. False Positive Rate Trade-offs
A 3-axis accelerometer can detect a fall pattern — rapid acceleration spike, orientation change, then stillness. The challenge is distinguishing that from a worker bending down to pick up a tool, setting down a heavy load, or sitting on a bucket...
The 4-Hour Window: Why Spot Inspections Miss Most Construction Hazards
A typical commercial jobsite with 200 workers gets 2-3 safety walk-throughs per day. Each takes 45 minutes. That leaves roughly 22 hours per day where conditions are unobserved by a human safety professional. Machine observation closes that window...
