Paystand is the world's leading blockchain-enabled B2B payments network, transforming commercial finance into a software-driven, zero-fee, and open ecosystem. Recognized as a CNBC/Statista 2026 World's Top Fintech company, Paystand delivers over a decade of on-chain payments experience to middle and large enterprises.
Paystand's network services more than one million payors that have moved $20+ billion in volume. With its acquisitions of Yaydoo, Teampay and Bitwage, Paystand's full-stack platform includes agentic AI, its USDb stablecoin, and AR/AP solutions on one tightly integrated network. Its non-profit arm, Paystand.org, advances the mission to democratize finance through Bitcoin and blockchain technology.
What We Do
We built the financial system we always thought should exist: zero fees, zero friction, just your money, faster. Blockchain automates receivables and payables, cuts time-to-cash, and turns every transaction into revenue instead of cost.
Why We Do It
The current system takes a cut from the people who build, create, and grow — and calls it the cost of doing business. We don't buy that. Every fee we eliminate compounds into growth. We're here to decentralize finance and hand the power back to the businesses driving the real economy — extended further through Paystand.org's work to democratize finance through Bitcoin and blockchain.
How We Do It
We don't wait for permission or for the industry to catch up — we build the future of finance ourselves, on-chain, in the open. Small moves now, monumental results later.
Join Us
We're not looking for people who want a job in fintech. We're looking for people who want to build what comes after it. Paystand is where you help lead a financial revolution instead of just reading about one. We stand on change. Come stand with us.
