UC company ThinkingPhones has rebranded to Fuze (the video conferencing brand it acquired in 2015), and secured $112m in new funding led by Summit Partners, bringing the company's total funding to $200m.
The company is targeting established brands in the market.
Fuze delivers mobility-enabled and analytics-driven business communications. In 2015, the company grew revenue by more than 100%, adding more than 175 new customers and expanding existing customer relationships.
In January 2016, Fuze was positioned by Gartner as a Visionary in the Magic Quadrant for Web Conferencing.
Expansion across Europe is a key part of Fuze's growth strategy for 2016. The company has already experienced substantial growth in Europe, increasing revenue from this market by 150% year-over-year and adding 60 new customers in the last 12 months.
The company's European headcount rose from 15 in January 2015 to more than 120 employees.
In January Fuze opened new offices in Germany and Switzerland to run alongside existing full business operations in the UK, the Netherlands, Denmark and France.
A new office has also opened in Australia.
"The way we communicate at work simply doesn't match up to the experience we expect in our personal lives," said Luca Lazzaron, Senior Vice President of International Operations, Fuze.
"Despite almost two decades of IP telephony and an established UC market, little has fundamentally changed. It's time for a revolution in workplace communication.
"The new generation of professionals expect voice, video, and collaboration to be instantly accessible from any device, and they expect it to simply work."
Steve Kokinos, CEO and co-Founder, Fuze, added: "Voice is only the beginning of our story. Work life is dynamic and unpredictable, and the new Fuze is all about flexible, always-on business communications, video conferencing, messaging, and collaboration. When voice, text, data, and video are 'fuzed' on a single platform, great things can happen."
