The comms stack was broken. Nobody had fixed it from the carrier up.
In 2018 our founders were running a 4,000-seat call center operation. Five vendors, three TLDs of dashboards, four separate bills, and an SLA that read like a horoscope. So they started building.
The market told us the answer was a “CPaaS” — an API for the carrier you couldn't see, a contact center you still had to bolt on, an AI layer rented from yet another vendor. Three boxes. Three contracts. Three places where something could break and nobody owned it.
We took the other path. We built our own carrier interconnects first, then the UCaaS layer on top, then the contact center, then the AI. One platform. One bill. One pager who answers the phone at 3am.
Eight years on, that thesis hasn't aged. Rozper powers communications for thousands of teams in 150+ countries — from two-person startups answering their first call with an AI receptionist, to global contact centers placing a quarter of a billion minutes a month.
“We don't want to be the most exciting telecom company on earth. We want to be the one you forget is even there — because every call just works.”
