High-Tech Gründerfonds Invests in Click-2-Call, the Next Generation of VoIP Technology

C2Call (Click-to-call) GmbH, a developer of a ground-breaking new Voice over Internet Protocol (VoIP) technology has received start up venture capital from High-Tech Gründerfonds and angel investors Michael Brehm – former executive director of StudiVZ – and Tapesh Sinha – Founder of Acctel Group. This investment will fund the internationalization and marketing of, the world’s first Java browser-based VoIP suite and the popular FriendCaller iPhone apps.

Developers of C2Call took a radical new approach in Internet Telephony by developing a Java-based internet telephony solution that starts in any popular browser and operating system without installation of software.

“Our vision was a true Click-to-Call (C2Call) experience where users don’t have to bother with prerequisite software installation and configurations – our aim was instant browser-based VoIP,” explained Michael Knecht, Founder and CTO of C2Call GmbH. “With the launch of and Apple’s approval of our FriendCaller iPhone app, we achieved the proof-of-concept and turned to High-Tech Gründerfonds for help in preparing for the next steps, namely the internationalization and marketing of C2Call.”

“Both the founders and angel investors are very pleased about the successful financing of the company,” said Martin Feuerhahn, Founder and CEO of C2Call GmbH. “Over the past four years of its existence, High-Tech Gründerfonds’ investments have become a desired “seal of approval” for all promising German start-ups focusing on high tech development. The High-Tech Gründerfonds not only provided investment, but opened its impressive network of portfolio companies to us and helped us to prepare our corporate structure and legal framework for the next growth phase,” Feuerhahn continued.

According to Andreas Quauke, Investment Manager with High-Tech Gründerfonds, market surveys show that PC-based VoIP is still only used by a small percentage of all Internet users. “C2Call is poised to change the market. We followed the fast development of this new Click-to-Call technology almost from its inception and were impressed with the speed and efficiency the small C2Call team pushed forward. The market potential of the new technology and the experienced team were the deciding factors for our engagement,” he continued.
