POK - Proof of Knowledge

What POK - Proof of Knowledge does

POK - Proof of Knowledge (operated by Amelay Corporation S.A.) is a Montevideo-headquartered digital credential platform that issues Open Badges 3.0–compliant verifiable credentials and NFT certificates anchored on public blockchains (Polygon, Ethereum, LacNet/LACChain). The platform implements the W3C Verifiable Credentials Data Model with decentralized identifiers (DID:key), holder-owned digital wallets, and cryptographic proofs that allow third parties to verify credential authenticity via public blockchain explorers independent of POK's operational status. Native LTI-compatible integrations with Moodle, Canvas, Blackboard, and D2L Brightspace, plus CRM connectors (HubSpot, Salesforce) and wallet exports (Google Wallet, Apple Wallet), support API-first automated issuance. The platform holds ISO/IEC 27001:2022, SOC 2, and 1EdTech Open Badges 3.0 certifications, and complies with GDPR, FERPA, CCPA/CPRA, Brazil LGPD, and Argentine data protection law.\n\nThe company serves universities, coding bootcamps, certifying bodies, corporations, and government agencies across 19 countries, with named customers including Trinity College London, Universidad de Guadalajara, Universidad Insurgentes, Politécnico de Lisboa, TOTVS, Mercado Shops, and RECLA/Inqaahe network members. POK uses a tiered pricing architecture: a 100% free unlimited web-based Open Badges 3.0 plan; a Blockchain Verify tier at $0.30/credential or $3,000/year (up to 50,000 credentials); and an NFT Ownership tier with volume-based prepaid packs ($0.80-$1.50 per credential) that includes white-label, custom-domain, and AI-driven Employability Index features.\n\nGo-to-market combines product-led freemium acquisition with enterprise field sales, API-first partner channels through LMS/CRM ecosystems, community-led adoption via education networks, and event-driven demand generation. POK has issued 1.5M+ credentials to 1,100+ institutions, was recognized by HolonIQ as a Top 100 Latin America EdTech in both 2024 and 2025, and maintains a 5.0 average rating across 65 verified reviews on G2, Capterra, GetApp, and Software Advice. The company closed a $12,000,000 funding round on January 15, 2025; investors were undisclosed. Co-founder and Chairman Guido Grinbaum leads the organization.

Direct peers

• Credly: Credly is the market-leading digital credentialing platform owned by Pearson, offering Open Badge-compliant credentials for enterprises, universities, and certifying bodies. It is POK's primary direct competitor across all three of POK's product tiers, including POK's explicit 'POK vs Credly' comparison content.
• Accredible: Accredible is a leading digital credential platform serving universities, professional bodies and enterprises with verifiable certificates, open badges and blockchain-anchored credentials. It is a direct competitor to POK's Blockchain Verify and NFT Ownership tiers, and POK explicitly markets 'up to 3x cheaper than Accredible'.
• Canvas Credentials (Badgr): Canvas Credentials (formerly Badgr) is Instructure's native credentialing solution, deeply embedded inside the Canvas LMS. It competes head-on with POK's Canvas integration and offers free Open Badges issuance to Canvas institutions, making it a direct peer especially within the Canvas ecosystem.
• Acreditta: Acreditta is a digital credentialing platform serving Latin American and European institutions with verifiable certificates and badges. It is one of POK's named comparison targets (POK vs Acreditta), making it a directly comparable competitor in POK's core LATAM market.
• Certifier: Certifier is a digital credential issuance platform targeting businesses, training providers and educational institutions. POK explicitly maintains comparison content (POK vs Certifier), making it a directly comparable peer for SMB and training-provider customer segments.
• Sertifier: Sertifier is a digital credentialing and badge issuance platform for educational institutions, training providers and corporate L&D teams. It offers comparable Open Badges and blockchain-verified credentials, positioning it as a directly competitive alternative to POK.
• Learning Machine / Hyland Credentials: Hyland Credentials (formerly Learning Machine) is a blockchain-anchored digital credential platform issuing verifiable records on distributed ledgers for governments, education and enterprises. Its blockchain-first approach directly parallels POK's NFT Ownership tier and verifiable credential technology stack.

Broad incumbents

• Parchment: Parchment (Instructure) is a broad incumbent in academic credential management, including transcripts, diplomas, and digital badging at scale for universities and learners. As a larger established player with overlapping capabilities in credential verification and learner records, it represents a broader competitive threat to POK in higher education.
• Digitary: Digitary (a Parchment company) is an established European digital credential platform enabling universities and graduates to issue and share verifiable academic documents. It is a broader incumbent with comparable offerings, primarily serving European institutions and competing with POK's ELM/Europass-aligned approach.

Emerging players

• Velocity (blockchain credentials): Velocity Network / Velocity Career Credential is an emerging blockchain-based verifiable credential and labor-market data network. As an emerging player pursuing decentralized career credentials, it represents a thematically adjacent peer whose adoption could validate or compete with POK's blockchain credential thesis.
