For millions of teams working in dozens of industries, day-to-day business gets done on the phone. So why — despite the huge leaps we've taken in design and usability — does most business phone software still look, feel, and act like it was born in the 90s? OpenPhone is changing that.
We’re a new type of business phone with a mission to help people communicate better and be more productive.
We’re backed by Y Combinator and some of the best venture firms around including Tiger Global, Craft Ventures, Slow Ventures, and others. We take pride in providing an exceptional customer experience and a product people love, which is why we’re excited that our customers have rated us the #1 VoIP Provider on G2.
OpenPhone is the modern, sophisticated answer to the clunky, outdated phone systems that have been slowing down businesses for years. With thousands of happy customers and several rounds of funding in just five years, it's safe to say we're onto something big.
