About

I'm Tsahi Levent-Levi, the voice behind BlogGeek.me. This is where I share my insights on technology, primarily focusing on WebRTC, CPaaS, Messaging, Disruption, and the occasional musing on Science Fiction.

To put food on the table, I offer consulting in these domains, publish reports, run WebRTC training courses, and operate WebRTC Insights. Oh, and don't forget to check out rtcstats 😉

In a world full of technological hype, confusion, and FUD, I aim to cut through the noise. My mission is to unravel these complexities, simplify, and explain them in the clearest, most direct way possible.

A bit about me

With over two decades in telecommunications, I've played various roles - from programmer and manager to marketer and CTO - in projects centered on VoIP and 3G. This includes developing a 3G-324M protocol stack from scratch and managing the team responsible for the H.323 protocol stack among other projects.

I co-founded and served as CEO of testRTC, a self-service SaaS company dedicated to testing, monitoring, and support for WebRTC applications. After selling the company to Spearline in 2021, I became their Chief Product Officer. Spearline was later acquired by Cyara in 2023, and I returned to focus on my independent consulting practice at the beginning of 2025.

Academically, I hold an MSc in Computer Science and an MBA focused on Entrepreneurship and Strategy. My background also includes several patents and chairing activity groups within the IMTC, an organization committed to multimedia standards interoperability.

Beyond the professional world, I'm a husband and father to two great kids (and a dog). I enjoy cooking, ballroom dancing, juggling, and kettlebell workouts.
