Cube3.ai

What Cube3.ai does

Cube3.ai (legal entity Cube Security Inc., DBA CUBE AI) is a blockchain security company founded in 2022 and headquartered in Palo Alto, California, with a European subsidiary in Kaunas, Lithuania. The company operates an Agentic Crime Prevention Platform that uses AI and machine learning to detect, predict, and prevent fraudulent activity on blockchain networks in real time — before malicious transactions execute rather than after the fact. Its core technology stack includes a proprietary in-chain blocking protocol integrated directly into customer smart contracts, enabling preventive intervention rather than post-incident response.

The platform is structured around three core products: Detect (real-time identification of malicious smart contracts and transactions), Protect (in-chain blocking of threats identified by Detect via a protocol integrated into customer smart contracts), and Manage (security operations and fraud intelligence management). Additional offerings include the Apex Fraud-Prevention Service (an enterprise sub-product within the Cube AI Intelligence Platform) and Phantom Ledger (a private fraud intelligence briefing service for fraud, risk, compliance, and trust & safety professionals). AI capability types include anomaly detection for transaction threats, predictive analytics for crime forecasting, and autonomous agents that engage suspected fraudulent actors to confirm risk indicators. The platform is designed to operate without requiring customers to upload operational or transaction data, relying instead on Cube AI's proprietary intelligence sources and cross-customer analytics.

Cube3.ai sells via an enterprise field sales motion targeting banks, fintechs, centralized/decentralized exchanges, VASPs, smart contract developers, and government/law enforcement agencies. The business model is SaaS subscription with annual billing and quote-based custom pricing, structured around Order Forms under the Cube AI Intelligence Platform Terms of Service. Customer acquisition runs through a "Request a Demo" consultative sales process with no self-service or marketplace distribution. The company holds ISO 27001, SOC 2 Type II, and GDPR certifications, and is a member of the Global Anti-Scam Alliance. To date, Cube3.ai has raised approximately $26M across multiple funding rounds led by Blockchange Ventures and Beacon, supplemented by EUR 4.9M in EU co-funded R&D project awards spanning 2023-2027.

Direct peers

• Chainalysis: The leading blockchain analytics and compliance platform used by banks, fintechs, VASPs, and government agencies. Directly comparable to Cube3.ai on target customer base (financial institutions and crypto businesses) and overlapping use cases in fraud detection, AML, and transaction monitoring, though Chainalysis is more compliance/forensics-focused while Cube3.ai emphasizes real-time prevention.
• TRM Labs: Blockchain intelligence platform providing transaction monitoring, wallet screening, and fraud detection for financial institutions, crypto businesses, and public sector clients. Competes head-to-head with Cube3.ai for bank and fintech fraud-prevention budgets, with similar AI/ML-based risk-scoring methodology.
• Elliptic: Blockchain analytics company offering transaction screening, wallet attribution, and fraud investigation tools to banks, exchanges, and regulators. Closely comparable to Cube3.ai's Detect and Phantom Ledger capabilities across the same financial-services and crypto-ecosystem customer set.
• Crystal Blockchain (Bitfury): Blockchain analytics and compliance platform providing transaction monitoring, risk scoring, and investigation tools for VASPs, banks, and law enforcement. Overlaps with Cube3.ai on fraud intelligence, AML, and crypto-compliance workflows.
• Scorechain: Blockchain analytics and AML platform serving crypto exchanges, banks, and regulators with risk scoring and transaction monitoring. Comparable to Cube3.ai in target customers and VASP compliance focus, with similar geographic emphasis on European markets.
• Solidus Labs: Crypto-native market integrity and fraud surveillance platform serving exchanges, brokers, and regulators with real-time trade and transaction monitoring. Closely comparable to Cube3.ai on real-time, AI-native, crypto-focused fraud prevention for exchanges and VASPs.

Broad incumbents

• CipherTrace (Mastercard): Acquired by Mastercard in 2021, CipherTrace provides blockchain analytics and crypto-asset intelligence to banks, exchanges, and regulators. Comparable to Cube3.ai in fraud and AML use cases but embedded as part of Mastercard's broader payments-and-security portfolio.

Emerging players

• Sardine: AI-driven fraud prevention and compliance platform for fintechs and crypto companies, covering onboarding, payments, and account takeover. Comparable to Cube3.ai's dual traditional-payments + crypto positioning and its focus on real-time AI-based risk decisions.
• Alloy: Identity and fraud decisioning platform for banks and fintechs, including transaction monitoring and AML tooling. Partial overlap with Cube3.ai on fintech fraud-prevention workflows, though Alloy is more identity-centric and less focused on on-chain/crypto coverage.
• Sift: Digital trust and safety SaaS using AI for fraud, abuse, and content-risk decisioning across fintech, e-commerce, and crypto-adjacent verticals. Comparable on AI-driven real-time risk scoring but lacks Cube3.ai's proprietary in-chain blocking protocol.
