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 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. I highly recommend Tsahi for any WebRTC consulting engagements!

CP Engineering,

More than a technologist, Tsahi is an incredible coach and mentor. I would recommend him to anyone wanting to learn about this space, challenge their own status quo and help get the push needed to innovate.

We have a very unique video technology for augmented reality and remote assistance. Tsahi's expertise helped us make our product even better. Tsahi is a pleasure to work with and generally knocked it out of the park.

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. He's also extremely well connected and can find you a resource for any deeper dive you need.



Founder and CEO,
