What SureMark Digital does

SureMark Digital is a private, Utah-based cryptographic identity and content verification company founded in 2024 by Drs. Stuart Haber and W. Scott Stornetta, the researchers credited with co-inventing blockchain while at Bell Communications Research. The platform issues device-bound digital credentials (public/private key pairs) and verifies them through a real-time challenge-response protocol that returns an unambiguous verified/not-verified result, bypassing voice, face, or biometric comparison. Its product portfolio comprises SureCircle Identity Assurance (one-click identity verification for live calls, completing in under 20 seconds), Verified Web (a browser extension that authenticates content across YouTube, LinkedIn, X, Instagram, Facebook, and 37+ news publications), SureDoc (document provenance), and the underlying SureMark Credential. The architecture is intentionally edge-based (no third-party oracle) and offers unlimited Identity Challenges across all paid tiers to remove perverse incentives to skip verification.

The company's commercial motion is hybrid: product-led growth via a free browser extension and freemium content signing (10 signatures/month), inside sales for mid-market, and enterprise field sales for larger deployments requiring API/SSO integration and dedicated account management. Pricing is split into two subscription families: SureMark Identity (Starter $250/month up to 10 seats, Business $500/month up to 50 seats, Enterprise custom starting ~$1,500/month with unlimited seats) and SureMark Content (Verify free, Pro $29/month, Team $99/month, Platform starting ~$500/month for white-label and API). Annual billing carries a 17–28% discount. SOC 2 Type 2 compliance is described as underway. The customer base disclosed is thin—anchored by a UNJSPF pilot protecting 230,000 beneficiaries, an NILx sports partnership, and individual athlete signups—while the addressable use cases span executive impersonation, IT helpdesk vishing, BEC fraud, bank pretexting, newsroom provenance, and personal voice-cloning scams.

Revenue model

1. SureMark Identity — Per-Seat Subscription: Subscription licensing for SureCircle identity assurance on a per-seat, per-month basis with annual billing discount (17% savings vs monthly). Three tiers: Starter ($250/mo, up to 10 seats), Business ($500/mo, up to 50 seats), and Enterprise (custom, unlimited seats starting at ~$1,500/mo). All tiers include unlimited Identity Challenges — metering is intentionally avoided to eliminate perverse incentives to skip verification on 'low risk' transactions.
2. SureMark Content — Subscription Tiers: Subscription tiers for content signing: Verify (free, 10 signatures/month), Pro ($29/mo, unlimited signatures), Team ($99/mo, up to 10 signing members), and Platform (starting at ~$500/mo, unlimited members + API/CMS integration + white-label). 14-day free trials on paid plans. Revenue from individual creators and organizations subscribing to signing capabilities.
3. Enterprise Platform Licensing: Enterprise tier includes unlimited seats, API & workflow integration, SSO & directory sync, custom SLAs, and a dedicated account manager. Licensed per organization, not per seat at the top tier. Revenue derived from large organizations requiring broad deployment and integration.

Core offering

SureMark Digital issues cryptographic digital identity credentials (SureMark IDs) and operates a verification platform that lets individuals and organizations prove identity and content authorship using public-key cryptography. Its SureCircle product delivers real-time challenge-response identity verification during calls and messages, while Verified Web authenticates signed digital content across social platforms and news publications. The platform is delivered via browser extensions, iOS/Android apps, and an enterprise API.

Product overview

SureMark Digital is a cryptographic identity and content verification company founded by the co-inventors of blockchain (Drs. Stuart Haber and W. Scott Stornetta). The platform offers a unified portfolio of three interconnected products: SureCircle Identity Assurance for real-time identity verification during live calls and meetings; Verified Web (including SureDoc) for browser-side content authentication across social platforms and publications; and the SureMark Credential system providing cryptographic digital identities. The product architecture includes consumer browser extensions (Chrome/Edge/Brave) and mobile apps (iOS) that enable both verification of others and signing of one's own content. Enterprise tiers provide API access, SSO integration, and workflow automation for organizational deployment.

Products and services

• SureCircle Identity Assurance SureCircle provides one-click cryptographic identity verification during live calls, video meetings, or messages via a challenge-response system using device-bound digital signature key pairs. Designed for executives, finance teams, IT gatekeepers, and high-risk individuals who are targets of deepfake impersonation, BEC attacks, and social-engineering fraud. Verification completes in under 20 seconds and creates a Virtual Private Identity Network of pre-authenticated trusted contacts.
• Verified Web Verified Web is a content authentication system that cryptographically binds a creator's verified identity to specific digital content such as social media posts, news articles, videos, PDFs, and press releases. Targeted at individual content creators, publishers, newsrooms, and organizations that need to prove authorship authenticity and defeat misinformation or impersonation. Includes the SureDoc capability for signing documents.
• SureMark Credential The SureMark Credential is an individual cryptographic digital identity bound to a user's device, providing unforgeable proof of identity that can be challenged in real time. Each credential holder owns a private key on their device, and verification uses a challenge-response mechanism that returns an unambiguous verified or not verified result without voice, face, or biometric comparison. The credential is the foundation underlying SureCircle identity challenges and Verified Web content signing.
