About Us

What is Sphere?

Sphere is a payments API and web platform built for the next generation of the internet. By leveraging blockchains as a settlement layer instead of SWIFT, developers, merchants, and enterprises can start accepting and managing their digital payments with best-in-class compliance, accounting, tax reporting, and analytics.

Mission

Our mission is to create a more transparent and equitable payments layer for the world. By processing transactions through decentralized smart contracts, developers and merchants no longer need to spend weeks incorporating, paying legal fees, and providing documentation they might not have to get up-and-running. Enterprises can more efficiently serve customers globally and avoid extractive middlemen. Our success is measured by building a permissionless and credibly neutral payments protocol to give anyone in the world a seat at the table, and participate in global commerce.

Culture

We are obsessed. With our craft, and with providing the best possible customer experience. Our co-founders are both technical, and we pride ourselves on a strong engineering and design culture. We like to work hard. Although our management style is hands-off, and we prefer you set your own hours to maximize output, our team typically enjoys working for most waking hours throughout the week. At this stage, we consider all of our employees as co-founders, and believe in a flat, high performance - high reward structure where you will get out what you put in.
