About Poynt

In 2013, our founding team recognized the lack of smart terminals in the market, so we set about reimagining the ubiquitous payment terminal into a connected, multi-purpose device that runs third-party apps.

As smart terminals become mainstream, Poynt OS sets the standard as the open operating system that can power any smart payment terminal worldwide. Combined with our Apps ecosystem we are creating a new app economy for merchants and allowing developers to write once and distribute everywhere.

Fuelling our growth are some of the Valley’s top VC firms and leading global payments and fintech companies including Elavon, Google Ventures, Matrix Partners, National Australia Bank, NYCA Partners, Oak HC/FT Partners, Stanford-StartX Fund, and Webb Investment Network.

Headquartered in the heart of Silicon Valley in Palo Alto, CA, with offices in India and Singapore, we’re growing rapidly on a global scale so that merchants worldwide have the technology to transform their business.

Though we are quickly growing, one thing remains constant: we are a family. We approach challenges and opportunities head on, all the while growing and evolving as individuals and a company.
