The leading authority on CPaaS & WebRTC

Keep up and be up to speed on the world of communications, WebRTC and CPaaS

I am Tsahi Levent-Levi

I am a developer by heart. Always have been. The thing is, I found out I love writing and looking at the bigger picture of product and strategy. I joined the world of consulting and entrepreneurship when WebRTC was announced.

For the last 20 years, I’ve been working in the software communications space as an engineer, manager, marketer and CTO; changing my viewpoints so I won’t get bored.

Today I help companies simplify communication technologies, creating elegant and effective solutions. I also serve as Co-founder and CEO of testRTC, a company focusing on testing and monitoring WebRTC applications.

Tsahi is a true WebRTC expert. He and his team provided us with a thorough diagnostic of how we were using WebRTC technologies and provided good, actionable feedback on how we could improve our products.

Tsahi's contribution for our system design is very significant from both professionalism and Time To Market perspectives. I find Tsahi highly professional with great creativity and ability to think outside the box.
Eran Kalmanson
CTO, YouNow
In a short period of time we have found Tsahi's insights and suggestions on where to focus our efforts and which frameworks to use reduced the time it took us to reach our target and removed a lot of the risks involved in the process.
Craig Walker
Founder and CEO, Dialpad
We've been working with Tsahi for months and his insights and understandings of both the technology and the marketplace have been extremely helpful and shortened our development cycles materially.
