About Us

RHUBTM (which stands for Real-Time Collaboration HUB, and is pronounced as R  HUB) is a premier provider of web conferencing, remote support, audio conferencing and video conferencing servers that meet the needs of service providers and any organization. The Company's end users total over 2,000,000 in a variety of market segments including services, manufacturing, healthcare, education, and government.

Unlike competing solutions based on named licenses, every employee can use the RHUB productivity tools without any extra costs thanks to the RHUB floating license model. RHUB's patented breakthrough Guaranteed Attendance technology enables users of any platform to join meetings by using an Internet browser and requiring no download of any additional software.  Connect, collaborate and engage others as often as needed, with ultimate on-premise security, simplicity, speed, integration and branding.

The RHUB technology has been embedded in products from companies such as Hitachi, Zultys, Central Desktop and service providers.

RHUB is privately-owned and headquartered in Silicon Valley, California.



The company was founded in 2005 by Larry Dorie and Dr. John Mao. The product development started in 2003 by Dr. John Mao. Initially the product was to address the difficult firewall traversal issue in web conferencing. Soon the two founders found that the market needed an server solution to facilitate deployment, improve security and eliminate monthly subscription costs to end users. After much testing, they chose an embedded Linux-based server, which is not only reliable and cost effective but also consumed less than 4.5 watts of power. The product was immediately recognized by a leading magazine, CRN, as one of "2007 Tech Innovators Finalists".

Later in 2007, the product evolved to a “4-in-1” by delivering 4 applications in one server: web conferencing, webinar, remote support and remote access. In the same year, RHUB Communications invented the “RHUB WebView” technology which guarantees attendance, as it requires no download of any kind. The technology ensures that anyone using a browser can join a meeting from different platforms, including Microsoft Windows, Mac, Linux, Unix, iPhone and Android, so long as the attendee can browse the Internet. It effectively resolves the most difficult issue in web conferencing --- attendance failure due to firewall blocking, locked down computers not allowing installation of any software, Group Policies, Antivirus, operating system incompatibility, etc.  

In 2008, the company started to offer free audio conferencing services.

In 2009, the company released version 4.0, which rewrote the underlying screen capture engine and introduced new compression algorithms. Version 4.0 significantly improved the system’s performance and image quality.

In 2010, the company released version 4.2, which delivered multipoint desktop video conferencing. It also added enterprise functionalities such as clustered servers, webinar management, and enhanced Microsoft Outlook integration.

In 2011, version 4.3 was released. It introduced the HD VoIP audio conferencing. This further optimized the screen update speed to become one of the fastest products in the industry. In the same year, the RHUB TM-200 server was named as one of 11 Best Products of 2011 by the leading IT magazine for the US government, GCN.

In 2012, the company developed its own audio conferencing bridge to support integrated audio conferencing service, which allows regular telephone calls (PSTN) to converse with computer headset calls (VoIP) in one web meeting session. The entire conversation can be recorded together with the meeting presenter's screen updates. All callers, PSTN or VoIP, can be individually muted or unmuted. The current speakers are displayed.

In 2013, the company continued refining the audio conferencing functions including improved echo cancellation, recording conversion, toll free audio conferencing and integration with users' PBXs and third-party audio conferencing systems. The client GUI was completely rewritten for better user experience and faster cross-platform development. Development for iOS and Android mobile clients was launched.

In 2014, the company released the iOS client, improved echo cancellation, and improved performance to become the fastest solution for web conferencing. The system performs so fast that it can stream video played over a desktop together with audio streaming. Paid toll-free audio conferencing service was offered.
