Everything you need to seal,
verify, and prove.
One platform. Four layers. From cryptographic sealing to live board verification to public QR-based proof — every feature exists to make a single promise believable.
Product areas
Four layers, one unified platform
Each area is a complete product in its own right. Together, they make every seal unimpeachable.
Security
Every seal is mathematically tamper-evident. Multi-factor authentication, field-level encryption of secrets, and a cryptographic audit chain make our security verifiable — not just claimed.
- AES-256-GCM encryption at rest
- TOTP-based MFA for every seal
- Tamper-evident cryptographic audit chain
- X.509 PKI + RFC 3161 timestamps
Documents
Upload, seal, and share tamper-evident PDFs from iPhone or Mac. Immutable versioning ensures every revision is traceable, and enterprise cloud storage keeps your files where your team already works.
- Seal from iPhone on the job site
- Batch sealing on native macOS
- S3, Azure, Google Drive, SharePoint
- Immutable version history
Compliance
SOC 2 Type II ready infrastructure. Every sealed document gets a unique QR code — anyone can verify it without a login. Comprehensive audit logs satisfy even the most demanding regulatory requirements.
- QR verification — no account required
- SOC 2 Type II ready
- Instant public seal verification
- Full compliance audit log export
Identity
Custom professional stamps, verified credentials backed by live board data, and a public directory that puts verified professionals in front of the clients looking for them.
- Live licensing board verification
- Custom professional stamp designer
- Public directory — 14+ professions
- Organization & team management
All capabilities
Every tool in the platform
A complete view of what's included — from cryptographic primitives to public-facing verification.
iOS & macOS native
Built for Apple. Not a web wrapper.
Public verification
QR code on every sealed doc.
Encrypted at rest & in transit
Field-level AES-256-GCM for secrets; TLS 1.3 in transit.
MFA on every seal
A password alone can't produce a valid seal.
Cryptographic audit chain
Tamper with one event, invalidate the chain.
RFC 3161 timestamps
Legally defensible time-of-signing proof.
Board-verified credentials
45+ license types, live board data.
Team & org management
Custom roles, SSO, JIT provisioning.
Enterprise cloud storage
S3, Azure, Google Drive, SharePoint, Box.
GraphQL & gRPC APIs
Programmatic access to everything.
SOC 2 Type II ready
Third-party pentesting, 99.9% SLA.
Public directory
14+ professions across every U.S. state.
How it works
Claim, attest, seal, prove
We're a third-party attestation service. The board publishes who is licensed — we verify identity and attest that what you claim matches.
-
Claim Identity + license number
-
Attest We verify & cross-reference
-
Seal License status checked at seal time
-
Verify Anyone, anywhere
Claim your identity
You claim your professional identity and license number. This is provisional until we attest it.
We attest your credential
We verify your identity and cross-reference your claim against the board's published license data. You become a verified credential holder attested by us.
Seal a document
Upload any PDF and seal it with your verified credential. We check your license status against the board's published data at the moment of sealing.
Verified from anywhere
Anyone can verify the sealed document via the verify subdomain — no login, no account, no friction.
