What Vizidox does

Vizidox Solutions Limited is a privately held UK-based technology company operating the VDX API, a self-serve blockchain verification platform that allows developers and organizations to issue, verify, and revoke digitally signed credentials anchored on public blockchain networks. The platform is positioned as Provenance-as-a-Service, targeting use cases such as document authentication, academic and professional credential verification, supply-chain provenance, legal and compliance audit trails, and electronic document signing. The company is headquartered in Oxford with an additional registered address at Milton Park, Abingdon, Oxfordshire, and was founded in 2017 with a small team of 1–10 employees under founder and CEO Freddy Elturk.

The underlying technology is the Morphotech Blockchain API, a REST interface that accepts file uploads (PDF, photo, video, or metadata), computes cryptographic fingerprints using SHA256 and SHA3-256, signs credentials with ECDSA, and schedules them for batch issuance on selected blockchain engines to optimize transaction costs. Files themselves are not retained — only encrypted hashes are stored — which reduces data liability and supports verification independent of Vizidox's continued operation. Verification is a six-step process checking certificate integrity, blockchain anchoring, issuer authenticity, file integrity, expiry date, and revocation status. The platform is accessed via OAuth 2.0, exposed through a self-serve developer portal at api.vizidox.com, and listed on the Microsoft Azure Marketplace as 'VDX API'. A native Zapier integration and an adjacent Vizidox Signature e-signature service extend the product surface beyond the core API.

Vizidox monetizes through a six-tier subscription model (Sandbox free, Starter £20/month, Premium £55/month, Pro £170/month, Business £495/month, and bespoke Enterprise) with a 20% discount on annual billing and per-request overage charges on paid tiers. The go-to-market is product-led and self-serve for tiers up to Business, with Enterprise contracts initiated via direct contact. The company has not publicly disclosed funding, revenue, or named enterprise customers, and operates as a bootstrapped private limited company under UK jurisdiction.

Revenue model

1. API Subscription (Tiered): Vizidox generates revenue primarily through tiered subscription plans (Sandbox, Starter, Premium, Pro, Business, Enterprise) that grant a monthly allocation of API requests (credential issuance, verification, revocation). Plans range from free (Sandbox/testnet) to £495/month (Business tier with 25,000 monthly requests). Extra requests beyond the monthly allocation are billed at per-request rates (£0.03–£0.09 depending on tier). Annual billing provides a 20% discount.
2. Usage-Based Overage Charges: Each tier includes a base monthly request allowance. Requests exceeding that allowance are charged at a per-unit rate (e.g., £0.09/extra request for Starter, £0.05 for Pro, £0.03 for Business), creating a usage-based revenue component on top of the fixed subscription fee.

Core offering

Vizidox operates a Provenance-as-a-Service platform, anchored by the VDX API, that enables developers and businesses to issue, sign, and verify digital credentials and documents via blockchain-anchored records. The platform exposes a self-serve REST API with cryptographic hashing and digital signature capabilities, allowing integration of tamper-evident provenance into customer applications. A complementary Vizidox Signature add-on provides electronic signature functionality with blockchain proof.

Product overview

Vizidox offers a blockchain-based provenance and document verification platform. The core product is the VDX API, a self-serve blockchain API that allows developers to upload files, create digital credentials with metadata, issue them to various blockchain networks, and verify them perpetually. This is powered by the Morphotech Blockchain API which handles the underlying credential issuance and verification operations. The platform also includes Vizidox Signature, an add-on electronic signature service that provides certified delivery and storage for eDocuments, enabling users to execute agreements electronically with digital audit trails. The ecosystem supports multiple pricing tiers from free Sandbox (testnet) to Enterprise bespoke solutions.

Partnerships

Two partnerships are on record, tiered core.

• Microsoft AzurecoreTechnology or IntegrationVizidox is listed on the Microsoft Azure Marketplace as 'VDX API' (app ID: vizidoxsolutionslimited1662983968460.vdx_api). This integration allows Azure customers to discover, evaluate, and provision the Vizidox blockchain verification API directly from the Azure Marketplace, simplifying procurement and enabling integration with Azure cloud services.
• MorphotechcoreTechnology or IntegrationMorphotech is the underlying blockchain API technology powering Vizidox. The Morphotech Blockchain API (api.morphotech.com for Live, api-demo.morphotech.com for Demo) is the REST API engine that handles file uploads, credential creation, blockchain scheduling, and verification. Vizidox appears to be a branded frontend or partner operating on top of the Morphotech platform.

Emerging players

• OpenTimestamps: Open-source, free blockchain timestamping protocol. While it lacks a managed-API product, it pressures Vizidox's pricing on low-end, high-volume proof-of-existence use cases where customers can self-serve.

Direct peers

• Dock Labs: Decentralized verifiable credential platform offering credential issuance, verification, and revocation via API — substantially overlapping Vizidox's issuance, verification, and revocation feature set.
• Indicio: Open-source decentralized identity and verifiable credentials provider, with hosting and professional services. Targets government and enterprise use cases for tamper-evident credentials similar to Vizidox's positioning.
• Chainpoint: Open-source blockchain anchoring network for issuing verifiable timestamps and proofs of existence. Closely comparable technology stack to Vizidox's Morphotech-backed credential anchoring.
• Notarize: Remote online notarization platform with API access for embedding notarization into digital workflows. Overlaps with Vizidox Signature's certified electronic delivery and audit trail for legal-effect documents.
• OriginStamp: Provides blockchain-anchored timestamping and proof-of-existence for digital documents — directly overlapping Vizidox's credential issuance and verification on blockchain. Offers a free tier plus paid plans, comparable self-serve model.
• Trinsic: Developer-focused verifiable credentials and digital identity platform with a self-serve API. Targets the same developer/enterprise customer for issuing and verifying tamper-evident digital credentials.

Broad incumbents

• Microsoft Entra Verified ID: Microsoft's enterprise verifiable credentials service, integrated into the Entra identity platform. Represents the bundled-incumbent threat: enterprises already in the Microsoft ecosystem can adopt verifiable credentials without a third-party API.
• Alchemy: Major blockchain infrastructure platform serving millions of developers. As it broadens its product surface, adding credentialing or document anchoring features would directly compete with Vizidox while offering vastly superior distribution to existing customers.
• DocuSign: Global leader in electronic signatures and agreement lifecycle management. Vizidox Signature competes in adjacent territory; DocuSign's enterprise distribution and trust infrastructure represent a major competitive threat if it extends into blockchain-anchored audit trails.
