The Hard Reality
One Lapsed Policy. One Uninsured Sub.
That's All It Takes.
You already know this. A subcontractor shows up to your job site with an expired GL policy and suddenly you're the one holding the bag. The lawsuit names your company. The project owner looks at you. And that spreadsheet you've been "meaning to update"? It won't help.
Liability Exposure
An uninsured sub gets injured on your site. Average construction injury claim: $38,000. Without a valid COI on file, that's coming out of your pocket.
Project Delays
Audit finds a coverage gap mid-project. Work stops. Subs sit idle. Every day of delay costs you money — and reputation.
Manual Chaos
Spreadsheets, email threads, filing cabinets. You're tracking 20+ subs across multiple projects. Something will slip through the cracks.
How It Works
Three Steps to Bulletproof Compliance
No training manuals. No consultants. Just upload, verify, and relax.
Upload or Request
Drop in a certificate of insurance. Our AI reads every field — carrier, limits, endorsements, dates — in seconds. Or send a one-click request to your sub and their agent does the rest.
Auto-Verify
Sentinel checks every policy against your project's specific requirements. GL limits, auto liability, workers' comp, umbrella — all validated instantly. Non-compliant? You'll know before they set foot on site.
Stay Protected
Automated alerts fire 30, 15, and 7 days before any policy expires. Renewal requests go out automatically. You never have to think about it again.
Tools That Get Things Done
Everything You Need. Nothing You Don't.
AI-Powered Extraction
Upload any ACORD 25 certificate. Our AI reads every field — policy numbers, limits, endorsements, carrier info — with zero manual data entry.
Compliance Engine
Set requirements per project. Every certificate is checked against your specific limits, coverage types, and endorsement needs automatically.
Smart Alerts
30-day, 15-day, and 7-day expiration warnings. Automatic renewal requests. Your subs and their agents get notified — not just you.
One-Click Requests
Send COI requests to multiple subs at once. They get a branded email with a secure upload link. Their agent can even be CC'd automatically.
Project Dashboard
See every project, every sub, every certificate status at a glance. Color-coded compliance. Filterable. Sortable. Exportable.
Audit-Ready Reports
Full compliance reports with Excel and CSV export. When the auditor shows up, you're ready in 30 seconds.
Every Day Without Verification
Is a Day You're Exposed.
The contractors who sleep well at night aren't the ones who got lucky.
They're the ones who built a system. This is that system.
