Questions & Answers

As answered by people managing SubLien and CertShield.app.

What makes your product unique?

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.

Why should a person choose your product over its competitors?

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.

How would you describe the primary audience of your product?

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.

What's the story behind your product?

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.

Which are the primary technologies used for building your product?

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.
