Consulting & Advisory
WebRTC expertise on your side
I've spent 15+ years inside the WebRTC ecosystem - building products, running a company, advising teams from startups to Twilio. When your team hits a WebRTC challenge that's bigger than a Stack Overflow or an LLM answer, I can help.
Who this works best for
CTOs and engineering leaders building real-time communication products.
Teams with 5+ engineers and a product past the prototype stage.
Companies making a build-vs-buy decision on WebRTC infrastructure.
Three ways to work together
Tsahi In Your Corner
A WebRTC expert in your decision loop
For: Teams that need a WebRTC expert in their decision loop - not for a single project, but ongoing.
Monthly advisory · month-to-month
You're choosing between SFUs and the vendor comparison doesn't add up. You're about to commit to an architecture and something feels off. A browser update just broke calls in production and your team can't figure out why. These are the moments where having someone who's seen what breaks - across hundreds of WebRTC deployments - changes the outcome.
- Ongoing async access through your preferred channel - questions answered within a business day
- Fire drill response when production is on the line
- Monthly check-ins and quarterly deep-dives with your engineering team
- A monthly note with what I'm seeing across the industry and in your specific deployment
Scoped Consulting
A specific challenge, a defined outcome
For: Teams with a specific challenge, decision, or project.
Most engagements range $5K–$20K · 2-8 weeks
Recent examples
- Connectivity and quality optimization for a production WebRTC application
- Architecture review and roadmap for a real-time voice/video platform
- Third-party comparative review of AI frameworks for a vendor

Every engagement starts with understanding your specific situation. I'll tell you honestly what I can help with and what's outside my scope.
Team Workshops
Structured WebRTC upskilling for your team
For: Teams that need structured WebRTC upskilling beyond self-paced courses.
Starting at $3K · based on scope and team size
Custom workshops on WebRTC architecture, performance tuning, security, media quality, AI, and troubleshooting. Format: 3-session series over 1-3 weeks, recorded, with follow-up materials.
Topics include
- WebRTC architecture and signaling design
- Performance, congestion control, and media quality
- Security, encryption, and threat modelling
- AI in real-time communications
- Troubleshooting and debugging real-world WebRTC issues
Good fit, bad fit
Honest about what works. Honest about what doesn't.
Good fit
- You're building something where communication quality is a competitive advantage.
- Your engineering team is open to external expertise - not just a rubber stamp.
- You want honest, independent guidance - not a vendor pitch.
Not a good fit
- You need someone to write the code for you. I advise, I don't build.
- Your product is pre-MVP and you need a general-purpose developer.
What consulting clients say
As we set out to build a mission-critical real-time voice and video platform for public safety, we needed clarity on architecture, scale, reliability, and behavior under real-world conditions. Tsahi gave us a clear strategic framework for how WebRTC should be deployed, managed, and scaled in a high-stakes environment. His guidance helped us refine our architecture, avoid costly mistakes, and move faster.
We had the challenge of building a generative AI application with WebRTC video and audio broadcast. Thanks to our collaboration, we were able to reach the maintainer of the open-source repository and define an in-depth, sustainable solution. What I appreciated most about working with Tsahi is his proactive and informative approach.
Tsahi is like our WebRTC GPS. He doesn't just tell us where to go, he also warns us about the potholes along the way. He's guided us on how to implement things directly in our code - not just high level advice, but actual practical 'this is how you should build it' recommendations. That has saved us from a bunch of debugging marathons.
I have worked with hundreds of consultants across my Wall Street and startup career. I can categorically say that none have provided as much value as Tsahi Levent-Levi. He takes a very direct approach with his clients and is quick to let you know what falls inside and outside of his wheelhouse. Tsahi is also incredibly efficient with his time.
I met Tsahi when I just started out my company. Within a few days I realized he saved me weeks of work thanks to his expertise. It's now been 3 years and we continued to work together even though my team is much bigger.
