zerohash is the leading crypto and stablecoin infrastructure platform and the operating system for digital money, powering the next generation of financial services. Founded in 2017, zerohash enables banks, brokerages, fintechs, and payment companies to offer crypto trading, stablecoin payments, and tokenized assets without having to build or manage complex blockchain infrastructure on their own.

The zerohash platform supports three core pillars: Trade, Transact, and Tokenize. Through a single integration, customers can launch regulated crypto buy, sell, and custody services; enable 24/7 stablecoin-based funding, payouts, and settlement; and issue and manage tokenized assets with built-in compliance, risk controls, and reporting. By abstracting away technical, regulatory, and operational complexity, zerohash allows partners to treat digital assets as just another financial primitive: fast, programmable, and global.

zerohash is trusted by some of the world’s most recognized financial and consumer brands, including Interactive Brokers, Morgan Stanley, Stripe, Franklin Templeton, BlackRock, DraftKings, Gusto, Worldpay, Kalshi, One Pay, among others. Today, zero infrastructure supports millions of end users across brokerage, wealth, payments, and marketplace platforms globally.

The company is deeply regulated and compliance‑first, operating across the U.S. and internationally with licenses and approvals that allow partners to enter crypto and stablecoins with confidence. zerohash has become a trusted partner for enterprises seeking to modernize financial products while meeting the highest standards for security, risk management, and regulatory oversight.

To date, zerohash has raised over $280 million in funding from a mix of leading venture firms and strategic investors, including Morgan Stanley, Interactive Brokers, SoFi, Point72 Ventures, Bain Capital Crypto, Lightspeed Venture Partners, and more.

zerohash has been featured in top‑tier media outlets such as Bloomberg, CNBC, The Wall Street Journal, Financial Times, Reuters, Forbes, and CoinDesk, and its leadership team regularly contributes to global conversations on the future of payments, investing, and financial infrastructure.

At zerohash, we're building the infrastructure that makes digital money work securely, compliantly, and at global scale.

The zerohash Culture

All zerohash employees are guided by the following characteristics and core principles:

• Independence/Ownership - An ability to work autonomously. Join zerohash, pitch ideas, and shape the work you do.
• Passion - We are innovating quickly and challenging the status quo. We want you to think big, be creative and make a difference every day.
• Collaborative - A good attitude and respect for others. We’re teammates, not co‑workers. Everything we do is a shared success and equally a shared failure - we talk in terms of “we” not “me”.
• Initiative - An ability and passion for learning and asking questions. We will champion you, challenge you and push you to achieve your best - and we expect you to do the same.
• Empathy - An ability to listen, respect, and understand your co‑workers, customers, and everyone you interact with no matter how different they are to you.
• Adaptability - An ability to respond quickly. We are in a fast‑paced industry and so we expect you to be creative when solving a new problem and comfortable under pressure.
• Transparency - We believe that transparency is critical to empowering everyone to make the best decisions, both the company to its people and vice versa.
• Integrity - Integrity creates trust. As both an organization collectively and as individuals, it is our most valuable asset.
