Venturi Wireless named Bret Sewell as its new president and CEO. Sewell previously served as president of SnapTrack, Inc., a $50 million company that created the high-precision location-based wireless services market. 
Sewell pioneered SnapTrack partnerships with DoCoMo, KDDI, Sprint, Verizon, Alltel, Bell Mobility, SK Telecom, KT Freetel, China Unicom, and other carriers, as well as with wireless equipment manufacturers such as Motorola, Texas Instruments, Samsung, LG, NEC, and Alcatel. Earlier in his career, Sewell was the managing director of the Asia Pacific Divisions of Aspect Telecommunications and Octel Communications.
In addition, Tomas Isaksson, former CEO and chairman of the management board at Vodafone Netherlands, has joined Venturi's board of directors.

- In November 2005, Venturi Wireless, a start-up based in Sunnyvale, California, introduced its optimization suite for consumer applications and wireless devices ranging from feature phones to smartphones and PDAs. Venturi Wireless aims to significantly improve the performance of multimedia services on wireless devices, by providing an optimized media server and client application capable of accelerating downloads up to three times. Video/audio streams would start two to three times faster. The architecture scales to enable mobile operators to meet the demands of the broad consumer market, supporting up to millions of optimized user connections without any degradation in service quality.
The VClient acts as a transparent “media inter-mediator�? to the media server, using bit-rate estimation of network transmission speeds for smoother playback of multimedia applications. Client- and server-side audio/video buffers keep the data stream from freezing during playback.
Venturi's "Adaptive Airlink Optimization" technology transparently replaces Transmission Control Protocol (TCP), including the User Datagram Protocol (UDP) for video, with a patented Venturi Transport Protocol (VTP) that overcomes the high latency and high packet loss issues that plague even next-generation wireless networks. VTP uses rate estimation to transmit data at full network speed, thus eliminating TCP's inefficiencies. VTP avoids TCP's congestion control reactions, which cause high latency and back-offs, leading to faster speeds and fewer dropped sessions, interruptions, and connection time-outs. Venturi said VTP also improves multimedia speed and reliability even in poor radio frequency (RF) conditions.
