Notabene

Notabene is the trust layer for global crypto money movement, established in 2020 to address the challenges facing the crypto industry's enormous potential. The company emerged in response to FATF's Crypto Travel Rule, viewing compliance not as a hurdle but as an essential foundation for bringing trust and legitimacy to the crypto space.

Core Products and Services

Notabene provides three interconnected layers of pre-transaction coordination infrastructure:

Notabene Flow - The first open stablecoin payments platform for businesses, introducing new payment capabilities like pull payments, push payments, and recurring subscriptions. Flow enables merchant-initiated payment requests, streamlined disbursements, and automated billing cycles for subscription services.

Notabene Transact - Transaction authorization platform that automates pre-transaction decision-making, turning Travel Rule compliance requirements into faster settlements and fewer blockers to revenue. Transact supports multi-party flows, wallet checks, and jurisdiction-specific rules with real-time policy enforcement.

Transaction Authorization Protocol (TAP) - An open protocol for exchanging pre-transaction messages, standardizing how counterparties discover, validate, and authorize crypto transactions before funds move. TAP uses signed Transfer Requests and encrypted messaging to authorize payments securely across wallets, exchanges, and smart contracts.

Key Strengths

Notabene operates the world's largest Travel Rule-compliant transaction authorization network with over 2,000 verified financial institutions across 100+ jurisdictions. The platform has processed more than $1 trillion in compliant transaction volume, with $600 billion from stablecoin transactions alone. The network achieves an 85% straight-through processing rate for transactions, demonstrating exceptional operational efficiency.

The company's founding team brings extensive experience from ConsenSys, Harvard, Deutsche Bank, and early Bitcoin startups. Two founders, Pelle Braendgaard and Andres Chomczyk, personally experienced regulatory challenges running early Bitcoin startups (Kipochi, Mondome, Yaykuy, and 37coins), which informed their approach to building compliance infrastructure.

Notabene's technology emphasizes security and privacy with end-to-end encryption across the full transaction lifecycle, optional managed PII services, role-based access controls, and fully auditable data custody. The decentralized architecture eliminates single points of failure while meeting global data residency requirements.

The platform is trusted by 240+ institutions including industry leaders such as Copper, Luno, Crypto.com, and Bitstamp. Founding partners for Notabene Flow include major payment orchestrators, custodians, exchanges, banks, wallet providers, and stablecoin issuers. The company is backed by Y Combinator, Green Visor Capital, and Castle Island Ventures.
