About Square

We believe the economy is better when everyone has access. When everyone has room to grow. No one should be left out because the cost is too great or the technology too complex. So we’re building easy tools to empower and enrich people. Tools that shorten the distance between having an idea and making a living from it—because we believe in fair and square. We started with a little white card reader but haven’t stopped there. Our new reader helps our sellers accept chip cards and NFC payments, our Cash app lets people send money instantly, and we’re building easy tools for customers, too. We’re empowering the electrician to send invoices, setting up the food truck with a delivery option, helping the clothing boutique pay its employees, and giving the coffee chain capital for a second, third, and fourth location. We’re here to help sellers of all sizes start, run, and grow their business—and helping them grow their business is good business for everyone.
