Tsahi Levent-Levi
Tsahi Levent-Levi
Spearline, Israel
I am Tsahi Levent-Levi. The person behind BlogGeek.me and Chief Product Officer at Spearline. My blog focuses on rumblings about technology usually boiling down to WebRTC, CPaaS, Messaging, Disruption and other topics (Science Fiction anyone?) To put food on the table, I also consult in these domains, publish my own reports and run a WebRTC training. During the past decade (and then some) I have taken part in the development of various telecommunication projects - mainly those related to VoIP and 3G. I've done so as a programmer, manager, marketer and CTO. This included developing the 3G-324M protocol stack from scratch, as well as managing the team that was in charge of developing and maintaining the H.323 protocol stack, along with other interesting projects. I was the cofounder and CEO of testRTC, a self service SaaS company focused on testing, monitoring and support for WebRTC applications. In 2021, we sold the company to Spearline. These days I am working as a consultant, analyst and entrepreneur on anything related to VoIP, but it mainly focuses on CPaaS, WebRTC and their potential for disruption. I have an MSc in Computer Science and an MBA degree with a focus in Entrepreneurship and Strategy. Included in my resume are a few patents and being the chairman of different activity groups in the IMTC – an organization focused on interoperability of multimedia standards. You can use the social media links to reach me or learn more about what I do and where.
