Next-generation card issuing and embedded payment platform. San Francisco CA, raised $100M+, built by former Braintree and PayPal engineers for enterprise-grade card programs.
About
Highnote is a next-generation embedded card and payment platform built by fintech industry veterans from Braintree and PayPal. Founded in 2020 and headquartered in San Francisco, California, the company has raised over $100 million in funding. Highnote targets enterprises and growth-stage companies building sophisticated card programs that require more configurability and commercial terms than first-generation BaaS platforms provide.\n\nHighnote's platform covers card issuance, transaction processing, ledger management, and rewards program infrastructure through a unified API. A key differentiator is its modern ledger architecture, which provides real-time financial position tracking at the account and transaction level — enabling more accurate reconciliation and complex financial product logic than legacy processing platforms support. The platform supports both consumer and commercial card programs, credit and debit structures, and multi-currency deployments.\n\nHighnote has positioned itself as the enterprise-grade option for companies that have outgrown first-generation BaaS tools or need more sophisticated financial product configurations. Its founding team's deep experience in payment infrastructure at scale informs architectural decisions that prioritize reliability, real-time data access, and compliance flexibility. In 2024 and 2025, Highnote expanded its commercial card capabilities and launched tools for managing complex interchange optimization across large card portfolios.
