For millions of teams working in dozens of industries, day-to-day business gets done on the phone. So why — despite the huge leaps weve 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.

OpenPhone is the modern, sophisticated answer to the clunky, outdated phone systems that have been slowing down businesses for years.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, its safe to say were onto something big.
