How it works

Four steps. Then it runs itself.

No training and no insurance know-how. If you can send an email, you can run COI Shield.

  1. STEP 01

    Add your subs

    Import a list or share one link — your whole crew is in.

  2. STEP 02

    They send it in

    Each sub uploads their insurance through a private link — no account.

  3. STEP 03

    AI checks it

    It reads the certificate and confirms the coverage you require.

  4. STEP 04

    You’re covered

    One clear board — and reminders go out before anything expires.

Try it

Scan a certificate. Right now.

This is what happens the moment a certificate lands — watch the AI pull the fields and check them against a GC's requirements.

Upload your list of subcontractors

Drag in the spreadsheet you already keep. Every sub on it becomes a row you can track — nothing to type in.

Upload your list of subcontractors

For your subs

The part your subs will actually do.

The #1 reason compliance tools fail: subs won’t sign up for yet another portal. COI Shield asks for one thing — the certificate — and never a password.

Register + upload

new subs

Send a project link. Your sub enrols their own company in the project and uploads their COI — you never add them by hand.

Upload only

imported subs

Already imported them? Send an upload link and they just drop the certificate — nothing to fill in.

Either way: no account, no password, no app to install.

Why COI Shield

One uninsured sub can become your problem.

If a subcontractor without the right insurance causes a loss on your job, the claim can land on you. COI Shield makes sure that never slips through the cracks — automatically.

Without COI Shield

  • Chasing certificate PDFs over email, one sub at a time
  • A spreadsheet that’s out of date the moment you save it
  • Finding out a policy expired only after something goes wrong
  • Scrambling to prove coverage when an owner or auditor asks

With COI Shield

  • Every certificate read and checked the moment it lands
  • One live board: who’s covered, who’s expiring, who’s short
  • Automatic reminders before any coverage lapses
  • Proof of compliance ready to hand over in one click

Protect yourself from liability

If an uninsured sub causes a loss on your site, the claim can land on you. COI Shield keeps that from slipping through.

Get your week back

No more email ping-pong or manual data entry. Subs upload their own certificates; the AI does the reading.

Be audit-ready, always

Every sub graded against your requirements, with a dated proof-of-coverage report a click away.

Security & trust

Built for the data you're trusting us with.

You're handing us your subcontractors' insurance certificates. We treat them like it.

Encrypted end to end

Every certificate is encrypted in transit and at rest — from the second a sub uploads it.

Your data, walled off

Row-level security means one contractor can never see another’s subs, documents, or projects.

We never sell your data

Your roster and certificates are used only to run your compliance — never sold, never shared.

Export or delete anytime

Take everything with you, or wipe it on request. Your data stays yours, always.

Why we built this

Chasing certificates is nobody's job. So it became ours.

We watched a general contractor discover — after the incident, not before — that a sub's liability policy had lapsed three weeks earlier. Nobody had done anything wrong. The certificate was in an inbox, the renewal notice was in another inbox, and the spreadsheet said everything was fine.

That gap is not a people problem, it's a tooling problem. Reading an ACORD 25, comparing limits against a contract, and remembering ninety days of renewal dates is exactly the work software should be doing — so we taught AI to do it, end to end.

COI Shield is built for the GCs who run lean: no procurement process, no training week, no "implementation partner". Import your subs, set your requirements once, and the chasing stops being your job.
