As answered by people managing CertShield.app and SubDoc.
CertShield.app's answer
Most COI tools only read the front page of a certificate. CertShield verifies the parts that actually protect you — additional-insured endorsement forms (CG 20 10 / CG 20 37) and waiver of subrogation wording — and pairs AI speed with human review: every uncertain result is verified by a person before it's published, and the customer always gives the final sign-off. We're also honest about limits: no tool can auto-detect a silent mid-term cancellation, so we mitigate it with agent confirmations instead of overclaiming.
SubDoc's answer:
SubDoc offers a self-service compliance platform with zero setup friction. Instead of forcing subcontractors to register accounts and create logins (the leading cause of collection delays), SubDoc sends a secure, passwordless magic link where vendors can upload certificates in seconds. It also features built-in AI-powered OCR that automatically scans uploaded documents to extract policy numbers, limits, dates, and endorsement compliance status (Additional Insured, Waiver of Subrogation) instantly.
CertShield.app's answer
Enterprise COI platforms like myCOI and TrustLayer cost $8,000–25,000 per year with annual contracts and sales-team onboarding — built for companies with thousands of vendors. CertShield delivers the same category of protection from $99/month, is live in a day, and has no lock-in. If you manage 20–200 vendors and currently track certificates in a spreadsheet, CertShield is built exactly for you. Every plan starts with a free 3-certificate audit so you can see results on your own vendors before paying.
SubDoc's answer:
Traditional compliance tracking platforms (like TrustLayer, myCOI, or Certificial) are sales-led, expensive, and introduce high friction for vendors. Operations teams choose SubDoc because it is fully self-service, publishes flat and affordable pricing transparently, supports international multi-currency tracking out-of-the-box, and eliminates subcontractor login friction entirely.
CertShield.app's answer
US property management companies (20–2,000 units) and small-to-mid general contractors who work with rosters of vendors and subcontractors — plumbers, roofers, HVAC, landscapers — and are responsible for verifying each vendor's insurance. Typically the owner, operations director, or office manager who currently tracks COIs manually.
SubDoc's answer:
SubDoc's primary audience includes commercial general contractors, subcontractors, property managers, compliance administrators, and mid-market operations teams who need to track insurance certificates (COIs), W-9s, and licensing requirements across 5 to 500+ vendors without enterprise complexity or cost.
CertShield.app's answer
CertShield started with a simple observation: a single uninsured vendor can turn into a six-figure lawsuit for a property manager, yet most small firms track insurance certificates in spreadsheets where expirations slip through and endorsements get missed. Enterprise tools existed but priced out everyone below the mid-market. As a solo technical founder, I built CertShield to give smaller firms the same protection — AI does the reading, a human verifies the results, and the price fits an SMB budget.
SubDoc's answer:
Tracking contractor insurance compliance is notoriously painful. Teams are usually stuck between chaotic manual spreadsheets or bloated, expensive enterprise software. SubDoc was created to fill this gap: providing a simple, modern, self-service tracker that automates the chasing via magic links and uses smart AI extraction to speed up verification, giving operations teams their time back.
CertShield.app's answer
Next.js and TypeScript on the frontend, Postgres for data, and Anthropic's Claude for AI document extraction — with per-field confidence scoring and a human review queue on top. US-hosted, encrypted in transit and at rest.
